if you wanna kick someone's ass in F@h the gtx 280 will do it, ati cards got the short end of the stick in terms of the way F@h is programmed, and from what i've read the 4870x2 has to mirror the ram between the cores(i can't exactly remember what they said) but essentially you only can use about 1gb of ram, unless you have two of them in crossfire at which point it will show as 2gb's
The X2 has 1gb per core, and like all other MCM and multi-GPU situation, must redundantly mirror the VRAM between the cores in all applications. Its marketing as a 2GB video card is just shlock.
I'd keep in mind that the X2 can realistically expect some real performance boosts from driver optimizations; it really is a driver dependent card from what I've heard. So it might end up even more powerful than it is now.. on the other hand, the GTX280 is irrevocably better in certain games.. I'd still lean further towards the X2.
One other thing to keep in mind, I hear the 4850X2 is supposed to be released in september, and two 4850 in crossfire are very equal to the 4870x2, though I dunno if that will remain the case through transition to MCM. Worth thinking about anyway.
