hey dudes,

my build:
FX 8320
8 gig ram
MSI 990FX

i live in Egypt and i was shocked when i saw MSI 280x and MSI gtx 770 at almost the same price. however, whats keeping me from buying the 770 is the fact that i have a FX 8320 and MSI 990FX.

so should i stick with an all AMD system with Mantle support or go with the more powerful and efficient 770?

thanks
