Which CPU to Choose for New Test System?

Hey guys,

Not to crush dreams or anything but there's something I have to say, as a guy who already did this for a living for a few years and does it on the side now...

First off, you're opening yourself up to very large liabilities if you're not thorough and meticulous. If you're having to ask for help putting together a rig to test other systems on, this likely isn't the best idea to pursue on your own. If you're reasonably young, I'd suggest picking up a job at an existing computer repair place to start with (even if it's just part time), get your hands dirty when somebody else is liable, before then stepping out on your own. I literally fixed thousands of computers before I started my own place; that's not an exaggeration, I fixed about 40 computers a week for the better part of 3 years.

I'd especially recommend tinkering on your own hardware with Linux first before you start trying to get paying customers. There's a lot of damage that you can unintentionally do to a computer when you're trying to fix it using tools and software that you don't already understand well. Because coming from my perspective, computers that were fixed by "a tech-guy" were generally messed up worse than a computer just coming in off the street with some issues. Also they were ALWAYs still infected (actually getting rid of all the malware on something is much harder than people expect or think) and even though it may be reported as clean on the tools you run, there's still things they miss. Its so big a problem, I actually stopped offering virus removal - I'll back up their stuff and re-do the OS ground-up for the same cost as somebody else's virus removal service because it's better, you KNOW its clean instead of just thinking it, and it'll save you countless hours trying to run down every rabbit-trail of an issue.

With that all said; a tech bench with a nice i3 would be more than enough. Most computer repair work is Hard Drive limited anyways, and even the most basic CPU is capable of running a HDD maxed out without any issues. Faster CPUs and more power will benefit you none, because it'll never be fixed faster than the HDD will allow.

I see...

Well, I guess I'm unqualified then, because I had to ask a question and some random, anonymous person on the Internet said I wasn't. Better pack it in.




Sir, I don't know what is meant by "reasonably young," but I've been in the real world long enough to know it sucks. It's not a dream, and I would say that if it was my dream, you would've thoroughly crushed it. I have no intention nor desire to do this for a living (and in order for me to do so, I would have to rip people off, and I wouldn't be able to sleep at night if I did that). It's just something to get by and make me a more attractive candidate for a job. I got all this training and I'm still having trouble finding work. Oh yeah, like you can just show up at someone's door today, ask for a job, and they'll hire you. Ha! I wish it was that easy. Now that is a dream! Businesses are creeped out if you drop off your resume in person or even mail it (if they're not using an ATS), nowadays.

I'm not just some "tech guy" that thinks, "oh hey, I'm good with computers. I'll start my own business now!" I have my A+ and Network+ certifications. I went to a tech school to learn the knowledge to earn these and learn to fix computers. We didn't just learn from a book; we fixed real people's computers as well (mostly students' from other courses in the school) and messed around with some things on our own. And I fully expect you to scoff at this, as a veteran in the field, or think it's "cute" that somoene thinks they can fix people's computers just because they went and received training).

I understand I would be opening myself up to liability if something went wrong, which is why I plan on going legit as an LLC right away, so someone can't sue me for the shirt off my back if they're dissatisfied with my work or want to take me to the cleaners for some frivolty. I'm not stupid enough to not backup a person's data before performing any work on it. I wouldn't want someone messing with my machine before backing everything up. And just what kinds of tools are being referred to that I might use and irreparably screw up someone's machine? I've used a lot of utilities. And I have a working knowledge of Linux. I'm not as proficient with it as I am with Windows, but I can get around.

If you have so little confidence in my abilities, why even provide a suggestion? Why unleash me unto the world with my assumed subpar technical skills, frakking up other people's computers? I asked about a CPU suggestion on this board because I tend to favor AMD, but I know they've been lagging behind Intel for quite a while now. I wanted to make sure I had a clear focus, and that there wasn't something on the horizon that I should know about. I'm building this system for a very different purpose than what I normally would build one for, and I would never build one for anyone, because then they're going to see me as their personal 24/7 tech support. I figured the bottleneck would be the person's drive, but I had no idea how much computing power I could use before it would just be wasted. Which is exactly what I don't want to do: waste money. I was looking at something like the i3-4130 or the FX-6300, based on some things I read, which seem to be mid-range processors, but I know those can't be the only two options. Maybe I wasn't as clear as I could've been in my the OP, and maybe it warranted the response I got...but it sure as hell doesn't feel like it did.

I thoroughly expect you to laugh at my retort.
post #4 of 13
No laughing, I'm not here to argue with people, just answer questions and give advice - I don't argue with people on the internet, I've been here long enough, haha!

I didn't intend it to be discouraging or insulting, just a well-warranted warning, because all too often on the internet people will answer a question with no background and unleash somebody on the world - more often than not they have no context for their plan or actions and, as I saw countless times; do more harm than good. I didn't intend for it to sound like I was saying "you're just some guy" - quite the opposite, my intention was to make sure you weren't. That you had experience, that you had practice, that you weren't just going to wake up one day and think "I'm good with computers, therefore I should fix them" which is an absurdly common line of thought. I may sound jaded, and I may very well be, but my points are all very valid, as I've had to clean up messes made by inexperienced people more times than I can count.

One fun thing - if you build a computer well enough, it's actually really easy to not have to be their tech support for life. There's only 1 guy who's computer I've ever had to fix myself, and I've built dozens. It just takes the right mentality and building a solid computer from day 1. If you don't mess around with $500 computers and are clear on the cost of your repairs vs those of others, you won't have to deal with as many entitled people as you would expect.

As far as Linux goes, I can mess up somebody's computer with nothing more than Terminal and a Text editor. The generally overlooked rule is the more powerful the tool, the easier it is to do damage with it. A table saw will cut wood faster, but it'll do more damage to you than a hand-saw if you aren't careful. The most common use of Linux would be G-Parted; it is extremely useful, and very powerful, but if you're not careful, it'll mess up their partition map and it'll be a lot of work to recover, if you can at all. I also used it a couple times to force-flash firmware onto parts that were never meant to have their firmware flashed (primarily wireless cards that were acting up and I couldn't find a reasonably priced replacement)

Most HDDs you'll see are only capable of 50-80MB/s max and are usually running at much lower speed than that because they are handling a lot of small files. i3's will be more than enough power to max out a couple at a time.

My concern with AMD for a computer that will see a lot of up-time is historically (from my mass repair days) is they are more prone to failure. I dealt with dozens of bad AMD chips and only a single bad Intel chip (sadly it was a QX9775 so it was a PITA to hunt down a replacement chip for his Skull Trail rig). This isn't saying AMD is bad, I'm just saying they are more prone to failure - it's still rare, but less-so. I'm sure somebody will dis-agree with me, but you asked opinions and that's mine.

Other things of note: Cheap hot-swap bays are more headache than the money they save you short term. If you do any wire management on the PSU in your trouble-shooting computer, leave a SATA power cable totally loose (eventually you're going to have to plug in a hard drive to your computer, while it's still in it's old case). Buy a good PSU tester (my weapon of choice). Keep a basic PCIx16 graphics card, that does NOT require a PCI power cable handy. Keep an extra gigabit NIC on hand for testing in people's computers. And finally, and I cannot stress this enough, there are three rules for computers to never work on at all (other than to pull a HDD from): 1) Beige, 2) it has a DVD-ROM and/or CD-RW drive only, 3) 1GB or less of RAM.

so you want to run pc fixing company and stuff and yet you ask people how to bulid a rig for it? I wish you best of luck, you will need it.

Just the processor, not the whole damn rig!

Thanks so much for taking the time to post an insult in my direction.

if you want midrange good and stable cpu then look for i3's

I present you with the same question: if this is seen as such a pathetic attempt, why even bother providing a suggestion? The intent was clearly made, so why bother at all? Really, why at all?
post #9 of 13
because helping others is a good deed and it dosent matter if i like the person i help or not. Like i said i3's series are good mid range cpus with hyperthreading, they require less power than adequate amds and less heat also.

If your only going too be using it for

virus/malware scans, testing memory and hard drives, defragging, performing backups,
then you really dont need a powerful system smile.gif
