Ok, so i've been out of the loop for a bit and im looking to jump into Windows 7 from Vista 64 . Since Windows 7 has DX11, im looking to upgrade my vid card as well.

My current rig:

Q6600 2.6ghz (i think)
4GB Ram
8800GT 512MB
blah blah.

Anyways, is there a card I could purchase that has DirectX 11 capabilities around $200 that would out perform my aging 8800GT?
