I've been considering upgrading my graphics card for a while now, and I just recently found a really awesome price for it on Newegg for $121 (open-box). I'm bound to the AGP interface for now, so do you know what kind of performance I'd be able to get out of the X800 GTO, how much I could OC it, and how well it'd play on Oblivion (my current favorite game)? Thanks in advance.
