Nope don't seem to be getting any problems with
Games at moment, but thinking more towards future
when games will be using quads more. BF3 for example.

What would u class as low Marine? I get about 80fps(average) in bfbc2 dx11,
32AA, 16AF everything on high at 1920x1080.

Running Crysis 2 dx11 ultra settings and high res textures I get highs
of 70fps, lowest about 40fps. Cards temps get a lil higher on crysis 2
about 71/72c.
