If I were to buy a card around the release of the GTX 350. First I'd wait 2 weeks, then pick up a GTX 260 (216 Core Version) and call it a day.
Seriously who needs the equivalent of the raw power of 2 TWO!!! 2!!!! ****ING 2!!!! GTX 280's?
The 4870X2 is already overkill.
For all you Crysis lovers, **** Crysis.
