hello guys
i have some problem here and make confusing to choose vga card for 3d software such as blinder, max or maya, and 2d application such PS and AE.
some time i need gpu computing performance for vfx simulation or rendering and in other time i need for gaming performance
which one is better vga card for CG and gaming?
cuda or openCl?

2 280xs which is basically what i m running still run games that support crossfire perfectly.

games that dont seem to be stuck at about 50-50% load unless these games are just cpu bound .

maya i see supports crossfire pro which is the workstation card equivalent. I believe you can mod the drives to turn them into fire pro cards.. as far as the other programs i cant say
