Then you guys can help him in 12 months when he figures out his i3 won't run any of the new games worth playing at a frame rate worth bothering with. Crysis 3 makes the i3 cry like a little girl. Bioshock Infinite is CPU bound as well, it also like more cores. Planetside 2 won't play more than into 20s for frame rates on an i3. GTA5 coming in a few months is designed for 4 or more cores, and that fact isn't changing anytime soon.
Plus, on a dual core, BF3 omits rendering certain aspects to accomodate for lost performance. That's the ONLY reason the frame rates are even where they are.
@OP: Good luck with your overpriced dual core and the impending overhaul build in 6-12 months when you realize the frame rates are in the toilet. A good quad would be FAR better for you...even a SB i5.

That's a review of a SB i5 running on 4 cores then 2...the difference in frame rate is double...and he's using a GTX560 Ti SLI config...
Hmm...not CPU bound at all huh?
