So my motherboard just crapped out on me a few days ago. Im not looking to uprade my processor (939 AMD 3500+) anytime soon, but since I am going to replace my motherboard with an Asus A8N-SLI Deluxe and my cheap 19" HP lcd monitor with the 24" Samsung 2494SW monitor, I was thinking about upgrading my video card (6600gt) to an eVGA 9800GTX or 8800GTX. I'm currently at 2gigs of ram with a 600watt PSU. Will my system support the 9800GTX or 8800GTX? Also, which is the better one? I use my computer mainly for movies and occasionally for games.
