Will this bottleneck?

post #1 of 12
Thread Starter 
Would an i7 860@3.9/4GHz bottlneck 2x6970s at 1080p? I just want to play BC2, Metro, Crysis, and BF3 when it come out maxed(I know BF3 can't be sure). If I have to, I can sell my DS and get a 2500k, but I'd rather wait for SB-E, and I don't want to sell my DS lite really(But I can), but I'd be getting slower RAM(1600 instead of the 2133 that goes with this combo on TPU).

I've seen 2x GTX 470 in SLI scale when a Sandy 2500K was overclocked from about 4GHz to 5GHz. Your cards are even faster. So they would gain pretty much from a overclocked Sandy VS the i7 870@3.9GHz I would think.

However, it will work fine. Point is you can gain even more with a overclocked Sandy

Well, with a 860 I can get it for 270 with 2133MHz RAM, but for 440 I can get 1600MHz ram and a 2500k. The MoBo for the 860 is a ASrock extreme, the p8p67 with the 2500k. I'd rather not spend that much though, so should I just save my DS and not upgrade?

If you have the money, upgrade and sell your old hardware. I say this because you are going to use two high-end GPU's in crossfire. You need all the CPU power you can get.

No bottleneck there, you're fine..

A Ci7 860 @ 4GHz is more than capable to deal with HD6970 CF..

CHEERS..

But at the same time, the bottleneck shouldn't be enough to warrant an upgrade before SB-E.

Yeah, SB-E is also going to cost alot so I should save.

Once you put AA and AF on, it becomes a GPU bottleneck in most games. Your CPU will not bottleneck 6970 CF. If it was quad-fire, then likely yes.

Yeah, I'll have AA and AF. I'll just save cause I want the 1k SB-E chip.
