Which CPU?

post #1 of 67
Thread Starter 

Hello, I could use some help determining which chipset I should get and not having much luck finding information nor getting help in the other forums orvia the stickies. I have roughly $700 (excluding $200 at Best Buy; who will price match just about anywhere). I'm probably going to be getting a watercooling kit if possible. I'm used to the high OC's of my i5 2500k's.

 

I've seen conflicting information about the newer chipsets ranging from Ivy Bridge isn't as good at overclocking than Sandy Bridge in general; to it's better in general. I've also seen people say Ivy Bridge isn't as good, but that Ivy Bridge E is as good if not better (I would expect it to be at least marginally so with the higher wattage) I've also heard Haswell is a "Pin-the-Tail on the Donkey" on a very big Donkey poster as far as chip quality goes.

 

I've also read that the temperatures in Ivy and Haswell can (and usually) are ridiculous to say the least because of poor TIM under the lid and I plan on Overclocking as much as I can before going to a sweet spot for general use, any credence to this? If so I would have to assume the delidding process would irrevocably void any warranty I might possess.

 

For more information on my specific uses I would point you to my sig (the link should be obvious enough) for a much more in depth (seriously) description.

Is the $700 for the MB/CPU & Watercooling stuff only? Do you have GPU's already? If so, how many do you have and how many do you plan to have? thumb.gif

I saw in your sig you have a 780 Classified. I would go with the Z87 chipset. If all your going to be doing is gaming then and i5 will be fine. Any i7 will give you a little bit better benchmarks. Your water cooling is going to add up quickly.

You will need a 780 Block too which is another $120 plus some fittings for it. Depending on your case you may want to change the radiator size or get another one.

These are pretty good boards and should overclock well. It mostly depends on your CPU though.

You're asking which CPU would be better, not which chipset. The chipset is like P67, Z68, Z77, Z87, etc.

 

Right now, I think a video card upgrade is far more worth your money than a CPU upgrade. The 2500K is still quite a formidable force to be reckoned with.

 

I would replace that GTX 460 (which is likely not giving you any performance benefit by having it do PhysX over your 780) and just add another GTX 780. I would also get a very good solid state drive and I would also replace the Deskstar (the "Deathstar").

Oh uh, I explained it in the other thread but I'll be upgrading the motherboard and cpu of the Chiller ReSpec rig in my signature and hopefully get at least an entry level watercooling kit. As I said I have ~$200 at Best Buy in addition to the $600-700 in cash. I'd prefer to keep within a $700 budget (using the $200 @ Best Buy) but I could spend a bit more it seems.

 

I'm having to build a new PC either way since my mom's toasted itself, I have a fair few unused (or very little wear and tear) parts that would be a major upgrade for her lying around in packages. I just figured it'd be better to get a newer chipset (motherboard) and the cpu to go with it since I'm not seeing too much in the way of 1155's.

 

Thanks so much for replying, you don't know how frustrated I was getting.

What other thread?

 

I still stand behind what I said: I don't think it's really worth it to buy a new CPU if you already have a good 2500K. Also, you have a Z77 motherboard, so if anything, you would want to spend less and just get a 3570K or 3770K.

 

Or, don't buy anything except for a top-of-the-line water cooling system. Get the best of the best, y'know?

The other thread is here. I posted here in the CPU subforum to get help choosing the CPU since, I've been waiting for replies for days trying to determine which models are better. Almost a week if you include the thread I made in general when I was on the fence between AMD and Intel. My 2500k isn't in so great of a condition anymore it started BSOD'ing for some reason and I wasn't able to get it stable at stock either so I'm RMA'ing it (as soon as I can find the blasted plastic cpu case; which seems to have fallen out if the cardboard inside the cpu box), if it were in any shape I would test out the P8P67 Pro motherboard I have lying around to see if that board was still viable (don't know I upgraded to a Sabertooth after my H60 took the cpu out when the pump died)

Agree with TwoCables. I thought you need a whole new system for your mom. I thought you were giving your mom your current system which is why I recommended the Z87.

If you are keeping the Z77 Sabertooth then yes, by all means just grab a 3770K. Grab a cheap LGA 1155 board and throw the 2500k in there for your mom.

If you are getting a new motherbaord & CPU for your man rig. I would highly recommend getting the latest 1150 chipset. I see no reason to get the 1155 chipset.

You have to bump your threads on a regular basis (about once per day). You can't just wait for replies. The longer a thread goes without a reply, the further down in the list it goes. Before long, it's 5+ pages back in the thread list and people are no longer seeing it.

 

Anyway, when are you seeing BSODs? Is your 2500K overclocked? If so, then what is it overclocked to? What is its core voltage in CPU-Z when running Prime95? What stress testing have you done? Be specific, including length(s) of time, the exact test(s) you ran, etc.

 

In addition: are you using an Offset voltage?

As I said I couldn't get it stable at stock (offset or manual) I was using an offset for 4.8 GHz at one point then I toned it down to 4.5 GHz offset and it was fine until the middle of last month, then I kept getting kernel power errors (when I looked in event logs) and 0x101 and 0x1E error codes. I was already planning on RMA'ing the chip when my mom's desktop died, so now she needs a new desktop but nothing too powerful so definitely not an i7 and it wouldn't be an upgrade if I got her a dual core. Hence why I was planning on upgrading my CPU and motherboard.

 

I tested it at both 4.8 GHz and 4.5 GHz up to the standards of the Sandy Stable Club;  Prime 95 Blend 12-18 hours, Folding @ Home, plus some benchmarks. It's over two years old at 4.5 GHz after a few months of it being 4.8 GHz I decided it wasn't worth the extra bill because of the electric bill to keep it cool so knocked it down to 4.5 GHz performed the same and it was running like that ever since, on offset. Tried manual and offset to fix it even at stock speeds so no go.

 

As for when it was bluescreening it was mostly random but it was happening during cpu-bound tasks most often such as video encoding or watch video, sometimes even browsing the web. I tested the RAM and PSU which many tests and on each computer I was able to get my hands on that supported DDR3, the GPU had already been tested and was the newest part there. In fact making sure the GPU was stable may have pushed the CPU over the edge with the number of benchmarks I ran.

 

As for bumping threads I did so regularly sometimes after 8 or 12 hours, some 18, and at the very longest 24 hours after no response.

I agree with what everyone else said, you should try fixing your current setup... a 4670k is barely an upgrade over a 2500k.

Have you tried a fresh Windows install, and have you tried the other motherboard? It's really hard to actually kill or damage a CPU, but related components like the motherboard/PSU/RAM or the drivers/OS go bad pretty easily.
