So I am planning to replace my really weak GT 430 with one of these cards:
ZOTAC ZT-50303-10M GeForce GTX 560 Ti OC Video Card

Sapphire Radeon HD 7850 11200-16-20G Video Card
http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=5273329&CatId=7387
Which one is better, and any suggestions that are better than these for under 180$ before rebate would be welcome. BTW is pci 3.0 compatible with pci 2.0?
