if someone gave me a 4890 to crossfire for free, i wouldn't do it... Hell if someone gave me a 5970 and 100 bucks, yet i could only run in crossfire mode, i would stick with my 4890This is somewhat of a lame thread. Anyone in their right mind would pick the single card over the crossfire solution if the single card gave acceptable framerates. How many of you are gaming at 2560 x 1600? That's the only situation where crossfire/SLI is warranted over a single card, as a single card at anything lower than 2560 x 1600 is plenty fast to give 50-70 FPS in any game, usually with a lot of AA and at max settings. The problem is that 2560 x 1600 is literally twice the number of pixels to push as even 1920 x 1200. .
