[QUOTE=Dj Yoshi]6800 Ultra for that price. Also, I'd suggest upgrading to a 3.6ghz P4 670j Prescott (that's probably gibberish to you, just remember 3.6GHz P4EE) if you can. The thing is a beautiful chip. Honestly, unless you do heavy video/audio/image editing, more than a gig of RAM is useless, especially in games. For instance, the first game to really NEED a gig of RAM was BF1942. Wanna know the next game? FarCry. It took years, YEARS for a gig of RAM to become the staple, and with good reason. Two gigs will take even longer, because with a gig less of the RAM is taken up by the operating system. Trust me guys, it's a waste of money. As long as you have a gig of PC3200 RAM, you're fine.[/QUOTE]
I have 2GB ram, and I would never, ever trade down.
2GB RAM == no swap drive at all == massive performance. The performance difference between 1gb and 2gb is not only noticible, it's quite an improvement, especially with Doom at max detail, or games like FEAR.
