well, thats just because you don't know what you are talking about.
Huh? I thought you were an AMD fan, Emi.
Anyway, I have an AMD64 laptop and it seems to run games quite well. That new Half-Life part 2 game runs pretty smoothly on it, I haven't noticed any slowdown or crashing. Then again, I play games about as often as Marlon Brando does pilates, so who am I to talk?
Anyway, AMD has a more efficient chip architecture and most programmers swear by an AMD chip's number-crunching potential. I won't lie-I like AMD because I dislike the Intel/Microsoft partnership, but since I got my AMD64 box, I have also noticed legitimate performance benefits over Pentium chips (and I use a P4 at work).
As for video cards, I'm really sorry, but I can't advise you too much there. My only insight into that is a pseudo-political one: N-vidia supports Linux while ATI does not. Naturally I'd go for an N-vidia card. Have you tried checking Tom's Hardware? They usually have pretty detailed reviews.
