Budget is $70. I usually don't play games and if I do is only CS 1.6 or Source (couple hours a week) so I don't feel like spending a lot of money on it.
Dell has 9800Gt right now for about $70 and 9600Gt for $50.
I'm having problem installing Vista from my XP machine. The computer detects the DVD but when it comes to the process "Please pPress Enter to Continue" it doesn't do anything when Enter is pressed. I've installed Vista on this machine before without a problem.
