Hi, i recently upgraded by rig

Intel core i7 920 2.66ghz
Dfi Lanparty x58 UT
Corsair 1000w

I currently have 1 4870x2, and i was wondering if that would be a bottleneck to my cpu if i added another one.
i havent really put together my parts yet, but i just wanna know if i would HAVE to OC my cpu before getting my second card, TIA :hello:

Well even if it was you have the i7 so there isn't much above that. I would go with 2 4870x2 in crossfire and rape CRYSIS! It might bottle neck but not by much... :sarcastic:

An overclocked i7 can handle a 4870X2 without a sweat. However, two 4870X2s will make it work a little. You definitely need to overclock the CPU with a 4870X2 to get the maximum performance out of each component. Two of these cards seems overkill especially with DX11 cards around the corner. Save your money and buy a next gen GPU instead.

For a pair of 4870x2s, you'll want to overclock a bit for sure.

Hm, I'll probably just sell the 4870x2 and get 2 4890 1gb and crossfire, take less power and gives me more headroom to OC my I7 ;)  Thanks for the help guys :hello:
