Hello,

I am planning of buying a ASUS m5a 78l m/usb 3 mobo and a Amd 3.5 Am3+ Fx 6-core Edition processor for an entry level gaming pc. however i found that the mobo supports only pcie 2.0 whereas my gpu (ie galaxy gt640) is pcie 3.0. will the gpu really work with the mobo and processor without much of a difference.

And

are the components mentioned above good for an entry level gaming pc. will be playing just cause 2 on mid to high settings

THANKS IN ADVANCE
