i would think they are pretty much the same, think gtx260 is officially been discontinued though probably making way for their dx11 40nm refresh.

hd5870 at the moment is ok ok, catalyst driver kinda blows, 9.9 crash a lot 9.10 beta gives me a mouse cursor thats like 10x bigger if i exit a game or watch a HD movie.

i like window version better y u want so many fans anyways?? adds more noise ; ;

wut resolution u planning to play games?? and r u planning to max everything when playing games?? kind of lots to consider le
