I've had this geforce3 since they came out, and it's not quite cutting it anymore. I wanna get a nvidia card b/c i've had bad experiences w/ ATI. I don't wanna spend more than like 200, I've been just browsing and saw the FX5700 Ultra had some good scores, but i might just get a FX5900, but i really don't know what's any good with those, like is a regular FX5900, tons better than an FX5700 Ultra? any info on this would be much appreciated, thanks.
