Can I run bf3?

[Battlefield4sure]

hmm I'm not sure if I must go with the 6770 or the 7750, but the link that TherealYeno gave me is a good find and it's also cheap. But the problem is that it's a pcie 3.0 and my motherboard has pcie 2.0. Will a 3.0 fit in a 2.0? And I also have some other question.
What means the DDR3 or the DDR5 on a gpu?

[TherealYeno]

A PCI 3.0 card can definitely work in a PCI 2.0 slot. IT refers to the maximum speed that can be transferred however a 7750 doesn't come close to using all the bandwidth of PCI 2.0.

GDDR3 and GDDR5 are typrs of memory used on video cards. GDDR3 is significantly slower than GDDR5.

But will I get full performance if I take a 3.0 and put it in a 2.0

[TherealYeno]

Yes. The card is reaching its max speed with the PCI 2.0
