ok right now my mobo has onboard video and i want to uprade to a nice video card. I am willing to spend about 150-200 dollars. if you have any advice i would greatly appreciate it
If you're willing to do a bios flash, than the X800GT0^2 is your best bet. If you're not willing to tamper with your videocard, then I would reccomend the 6800GS.
If you're willing to go used, I've seen X800XLs go for ~160 on ebay.
