Also, why such a good machine with a crappy/medial video card, 8800gs is like $20 more and 20x better. (exaggeration)
Well, first I'm not a gamer; only like games like car racing and the like. And so far I did not find a game that would kill that card. For example I played "Alarm for Cobra 11" at 1024x768 with no problem. Also one of my friends, who had bought COD 4 and realized he didn't have a rig to play it, installed it in mine and played with no problem at the same resolution.
Second, here in Poland, when I was buying, 8800gs was much more expensive than 8600gt (like $70 more as far as I remember).
So I bought that 8600gt for about $100. Do you know any good car racing games that would choke the card?
