Hi there, both cards offer similar performance, but if i recall correctly i think the 2 4890s are slightly better. I have an i7 @ 4ghz and with 2 x 4890 xfx not overclocked and they are brilliant cards, play anything i want to play on highest settings.
Sweet. Thanks for the input.
Also, I read an article that showed how 2x HD 4890's were better when used with a Phenom II 955 BE, vs 2x HD 4890's with a Core i7 920.
Is that because the Phenom II and the 2x HD 4890's are both made by AMD?
Could the opposite be said for 2x GTX 275's when used with a Core i7 920, vs a Phenom II 955 BE? (The Core i7 920 being faster w/ 2x GTX 275's than the Phenom II 955 BE w/ 2x GTX 275's?)
I'm a fan of the 1) overall performance of the Core i7 920, 2) the OC capabilities, and 3) haven't heard as many good things about the Phenom's and Phenom II's.
