Low FPS in games whats the bottle neck and what do you reccomend?

[anyOmouse]

So...
i recently bought a brand new pc from newegg in hopes of gaming at 1080p in 60fps (thats my vsync)
here is my pc : http://www.newegg.ca/Product/Product.aspx?Item=N82E16883229315

Games i play are BF3, Fallout NV and most modern First person shooters. what i was wondering is how can i get 60 fps as of right now on all low settings i get 30-40 fps in 1344x756. i know from experience that i cannot acheive any sort of stable overclocking without BSOD. any suggestions would be splendid

no suggestions? its probably my GPU but i'm not sure what my options are for upgrading as i am relativly new to pc gaming and my budget is 200-250$

Probably a Radeon 7850/7870. It would let you do what you want for $200/$250.
