I am getting a system of core i5 2500k (I'll probably keep it clocked since I don't have liquid cooling), 4-8 gb ddr3 ram, mobo with sli possiblity. The thing is, I need to get another 200 for the gpu (geforce gtx 560 ti), but as of now I can only probably get an emergency gpu for less than 50. Anyway, If I had the gtx 560 installed, what would my theoritical performance be on battlefield 3 on around 2000 x 1400 resolution (at the highest settings)?
