if yoyu have a 7850 or a 7870, your rig should perform pretty good. they can run games at high and ultra settings. just dont turn aa up so high
the bad thing bout your system is the CPU. zambezi chips are crap. your option of upgrading without changing the motherboard is to get a fx 6300. or if you dont want to spend money on that department, you can overclock your CPU
I don't know the specific model of my GPU.
The box got thrown away when we bought it, I've looked at every spec-reading tool I can find and they all just say 7800 series. So, should I just get a new CPU/Overclock it?
