my sempron stinks now lol.. i guess conroe?

My little sempron 2800+ kicked ass in gaming.. that is before oblivion came out.

I guess it cannot process all those AI, and when I have the sliders to max, I guess it can't process all the trees and objects and such.

I know this is my problem b/c I can play it at the lowest resolution or 1680x1200 (or whatever)
and still get lag on both.

And I'm sure 2 gigs of ram would help also.

So if I do get like a $200 conroe, how long will it last me in terms of gaming?

1680x1200
Why don't you play at a fucking sane resolution such as 800×600? Gosh, gamers just circle-jerk to stupidly high resolutions and for games to run at that they have to disable pretty much everything, turning them into a super-high-resolution Virtua Racing. I'd rather play 800×600 Oblivion with maximum detail.
