I7-950 vs i5-2500k build

I've been looking at building a new system for a while now but was holding off until sandy bridge was out. I was originally looking to use the i7-950 with gigabyte's x58a-ud3r board. The other option is to use the new i5-2500k since it is similar in price (the 950 would come from microcenter, ~$230) From what i've read, advantages of the 950 build include: hyper threading, 8mb L3 cache, triple channel ram, and more pcie lanes. What i am liking about the 2500k is the oc capabilities. But is that enough to make up for no hyper threading, and 2 less MB in L3 cache? Which would you choose and why?

thanks guys

I would think it would depend on what you intend to use your system for.

Or read the Tom's review on the main page. To summarize: the x58 mobo will get slightly more out of your xfire setup and in some cases outperform when encoding and doing general media work, but not by a noticeable amount.
The 2500k will overclock much higher, runs much cooler (if you want the 950 running at 4ghz you'll need the BEST air cooler or water cooling. If air - load will still be around 70-80c) and outperforms generally in games.

as others have said, interpret the facts for yourself, but when it comes to choosing between a 2yr old cpu and an efficient new cpu it's a no brainer in my opinion

Read this review. (not a article stating opinions, actual tests.) that compares the two processors mono e mono.

http://www.hardocp.com/article/2011/01/03/intel_sandy_b...


That site doesn't mention the 950 once, which is odd, given that neither the 920 nor the 980X can reasonably be said to be the direct competitors for the 2500K. The 2600K will challenge the 980X, sure, but why does that site not include benchmarks for the 950?

regarding x58's x16/x16 sli config and p67's x8/x8 config, there is less than 5% difference between them.


Actually, LinusTechTips did a test and dual 580s in 16x16x were as little as 0.2% faster than 8x8x

bandwidth has no real impact on performance..perhaps, if using two GTX 580's on the P55 or P67 platform..but, its negligible...as for the two processors listed..regardless of what your using the system for..1155 will give you solid results..

2500k vs i7950
http://www.anandtech.com/bench/Product/288?vs=100

Take a look at how a non-hyper threading cpu like the 2500k laughs at the i7950 in most cases...despite not having the 4 virtual cores, the 2500k holds its own, and much more! Additionally, you have a chip that oc's very well (it doesn't even need a very expensive motherboard to do it) costs less, and can outperform the more expensive chip...I'm a fan of the x58 platform..but it only makes sense to purchase what is cheap, and better...and that, my friend, is with the i5 2500K processor..

Pair that with a modestly priced motherboard like the P8P67 PRO ( http://www.newegg.com/Product/Product.aspx?Item=N82E168... ) and you have a very powerful computer that will handle your games/editing/rendering..etc...The choice is easy :)
