Whoa this card is quiet, it feels the same as the HD 2600. I'm so glad that its quiet because I remember on my previous mac pro 2.66ghz that the ati x1900's fan was freakin loud and I had to install an aftermarket fan on the x1900 to make it run quiet. Wow I played a little bit on Crysis and at 1920x1080(highest resolution) it runs fast on everything set to high, but on very high the framerate is kinda choppy. But I'm not a hardcore gamer so high is more than good enough and the graphics look sweet!! Another game I never really finished was doom 3 but with everything set on high, I've never seen the game look so good~ I cant wait till tonight to play one of these games!! I'm not a hardcore gamer and these are the only 2 games that I'm probably going to play but wow the 8800gt is very nice.
