That also could be the case, but I did play the beta as mentioned without any issues (I know everyone's setup is different
)and I think my rig can be seen in my profile, should be there? In any case I don't think your CPU would be a bottleneck either but if you're willing and haven't tried yet I would try just to see what difference it makes with turning off Hyperthreading, Speedstep etc to stop CPU throttling.
Worked wonders in BF3 back when it released especially as an example, completely eliminated FPS stuttering with Nvidia multi-gpu arrays. Ever since I've turned it off and stopped using the virtual cores and CPU throttling especially to overclock it hasn't been a source of any issues I may have had.
If turning off HT, Intel SS and the C states doesn't work I wouldn't know off the top of my head other than to wait for drivers as you mentioned, but I didn't have that issue even using drivers 332.21 while in Titanfall beta.
Hope it all works out!
