I've always prefered ATI cards for the fact that they're boxes seem to give more information that GeForces. But lately I've been noticing that a lot of people have problems with ATI cards.

Currently I have:
128MB ATI Radeon 9250 Xtasy Series

Could someone please recommend a better GeForce card (I'd like on that supports the newer shader versions; I've got a budget of about $100 dollars)? (I've been looking at the BFG GeForce OC 5500.)

Thanks!

Edit: also, it needs to be AGP 8x.
