Battlefield 3 Capable?

Yes you can hurry BF3 on low-med (mainly low) visuals settings beside fairly decent fps.

And all for any questions like these that you may have within the future, just append the following information.

Processor
Video Card
RAM
Operating System

example:
My PC

i5-2500k
Nvidia GTS 250
8 gigs of ram
Windows 7

see, nice and simple.

That is all you need to add, don't need to welter up your question near a bundle of useless information.
