My recent GPU is GeForce 9800GTX+ 512mb/256bit running on a Asus M4A78-E PCI-E 2.0 x16 and i want to upgrade it with a GTX 760 PCI-E 3.0 2GB/256bit or an AMD 7870 PCI-E 3.0 2GB/256bit .
Are the cards that I've chosen compatible with the PCI-E 2.0 16x slot ?
Will there be any loss or difference in performance ?

Yes, it will work. That card will run at 2.0 speed.

Yeah, it will work just fine, PCI-e 3.0 is fully backwards compatible to PCI-e 2.0, a 16x PCI-e 2.0 slot has sufficient bandwidth that you won't lose performance at all either.

Either will work, PCI-E is backwards compatible on the board and card meaning a PCI-E 2.0 card will work on a PCI-E 3.0 board and vice versa.
