I am just wondering if the 6800 GT 256 mb videocard is worth the $400 price tag for what I want.

I want to be able to run games like Sims 2, Rollercoaster Tycoon 3, Morrowind, and the new Elder Scrolls: Oblivion, occassionally the FPS games such as HL2, Far Cry, at good speeds, but reasonable graphics. The graphics don't have to be down to the extra detail where I can see the individual dust particles as if I was using a microscope, but decent graphics would be nice! I usually run my computer around 1024x768 so would that be good for the 6800 GT?

I have a $1500 max budget to buy an entirely new custom PC, and I want to get a reasonable graphics card for the games I want to play. Is there a cheaper card that will do the work?
