Upgrading to SB Strategy from LGA775?

post #1 of 21
Thread Starter 
As a current user of a E8400, I have had a strong urge to upgrade to the i5/i7 series in the past. Now that Sandy Bridge is out, I feel that it is a good time to upgrade (I've also heard of Ivy Bridge cpus being compatible with this new chipset, which would be a plus). As I am currently a student without much in terms of money, the only way I can see this upgrade happening is if I can resell my old parts (cpu, motherboard, ram) and purchase the corresponding sandy bridge parts. I am hesitant about this, however, and need some advice.

Selling
I have a E8400, a Gigabyte GA-EP45-UD3R, and 6GB of DDR2 800 RAM (2x2 xms2, 2x1 some other brand) that I would need to sell. Though I can cope with selling these first(or afterwards, whichever is better), I would be bound to my netbook until the upgrade is made, so the closer the better. My question is what would be the best way to sell these? Bundled, or separate? Through local sites like craiglist, forums, or merchant sites like Amazon/Ebay?

Also, as far as timing goes, would selling now and selling in a few months affect the price? What could I expect for my current parts?

Buying
I will most likely be purchasing an i5 2500K processor, 8GB DDR3 RAM, and a socket compatible motherboard. That's the part that is almost set (unless the 2600k gets cheaper). However, I am not sure about my timing. For the cpu, I've seen Microcenter's ad regarding the i5-2500K, which retails for 249.99 and qualifies for a $70 instant in-store discount (and the 2600K, which is 369.99-$90). I live close enough to the SoCal store, so purchasing from there is not a big hassle. These prices seem very reasonable, but leave me thinking that give or take a few weeks or months, these processors might even be maybe $20-30 lower. Am I correct in assuming this? Ram prices are cheap where I can essentially make a GB to GB exchange of used ddr2 to new ddr3, and it looks like prices are low enough. Motherboards are another area where my knowledge is fairly grey - All I want is the ability to overclock to the supposed easy 4.5ghz-4.7ghz speeds, and to be able to run my gtx460 and current parts without any trouble. Given this, am I safe in purchasing a lower-priced motherboard (such as the Asus P8P67), and what would I lose over a much higher priced motherboard?


I guess that's all the questions for now, as I feel I'm certainly asking much for a first post (though I've stayed a while before that). I would like to thank you guys before hand for even reading this.

Hello and welcome to OCN!

For your first question about when to buy the CPU: I would try to get it from Microcenter. You wont see prices like that online for a long time. I wish there was one closer to me. In the past I have noticed that Intel is VERY reluctant when it comes to dropping prices.

When buying DDR3 make sure you are buying RAM that has a decent balance between timings and speed. Sadly buying RAM works like this: Tight Timings / Fast Speed / Low Price, pick two. The key is to try and find a balance.

IMO the Asus P8P67 PRO looks pretty solid. If you compare it to motherboards that are 2 - 3 years old it is pretty close to the top of the line back then. IMO it is looking to be one of the best mid range P67 boards. (Go with the PRO version if you plan on ever using SLI)

What I've seen from Microcenter is that they are priced very good when bought in store. What I guess I'm saying is, this is at a price point in which I feel is great, but would waiting for the dust to settle cause me to 'lose' this deal? or am I safe to assume that there will continue to be sales at least to the same price range?

This, I need a lot of help with. My knowledge on RAM pretty much extends to socket type, speed, capacity, and ddr(x). Can you please expand on this?

Expected price? In all honesty, I want to spend the least amount possible to get the most performance (don't we all?). My current rig runs on a $100 motherboard that I only dislike because it wasn't capable of crossfire when I had my 4850. What is to gain with the higher models? I should note that because my psu is only 500w, the SLI option might not be available for this current build. This will essentially serve to satisfy my want for faster cs5/gaming/encoding for a year and a half (if everything goes according to plan).

I would also like to ask... how much do RAM timings and speed matter in terms of using a computer(and where does it affect the most)?

You have a really good Dual Core rig though.. P45 Mobo, 6Gb Ram..

Anyways you need serious voltage to achieve them speeds, like 1.5v/1.6v which would be not be best with a 32nm Chip, fine for a Bench but no where near safe for 24/7 usage..

That's not even true for one.

Secondly the SB chips are rated up to 1.52v via the Intel specs.

You will see 4.5/4.7 being the average while staying below 1.52v easy.

I frequently use programs that take advantage of more than two cores, and am constantly hitting the 2 core barrier due to having many active programs running at once (Ram also gets eaten up when working in programs like photoshop, or running one or two virtual machines). I also do a decent bit of photo/video work and would be glad to have some extra power.

As for the voltage, I have read that you needs those voltages for 5ghz+ (5.5? not sure... but I don't need to risk it for the improvements in speed), and that 4.5ghz is certainly reachable at safer voltages.

I recently did something similar... Sold my 775 rig to fund my 1156 rig.

I found that eBay is a great way of selling the 775 stuff. The $$$ it went for was surprising. No bundles, just ala carte.

IMO, the 2600k is the 1155 chip to go for. And Microcenter is *THE* place to get it.

When looking at the tradeoffs, this is how I'm seeing it...

CPU- e8400 $125 sell (maybe?) - approximately 10% - 179.99 2500k - 10% ca tax = -$85
motherboard- $90-$100 sell - 10% - $160 (ASus Mobo) - 10% = -86
ram- sell 6 gb $75 -10% + $80 8 gb ram + 10% = -20.3

This leaves me with a tradeoff of approximately 190$...
