Video card comparison

I would go with the 6800GS because it will perform a lot better the the vanilla 6800.

if u want to play oblivion at higher details id say go all out for the 7800gs. sure agp is dead, but the 7800 will last at least 2 years and a full year on high settings. also, if u play at 1280x1024 a 6800 any series wont let u run the game at high settings, ull be forced to run at medium for stable fps... and IMO that game is very hard to play when the details are that low its a shame... when the tree/grass distance is like 2 steps ahead of u... just makes me want to play css. IMO 7800gs if u can afford is the best card for oblivion on agp... and if ur budget is even bigger gainward makes a 7800gs with 20 pipelines and 512 memory, that will eat up oblivion... my 7800gs runs oblivon at 1280x1024 with around 45 fps on higher settings and hdr... i duno if the settings are maxxed or not but it looks amazing.

The 7800gs does what i expected it would do before i bought it. Im completely satisfied with it. Well worth the money.
