My GPU is the sapphire hd6850 vapourx ddr5 1gb. I installed gta5 and the game is running only in low settings. So I am planning to crossfire my hd6850. Can I crossfire it with a low end GPU.? I mean a ddr3 GPU. ? Sinc my budget is low, can I xfire it with an hd5450 or similar low end amd cards? Will it make changes to the gta5 gameplay?
My specs are..
I5 2500k, 2x4gb 1600mhz Gskill ripjaws
Asus p8 z77m mono
Hd6850 vapour x
Coolermaster 750wats psu.
Pls help.
