what are the minimum system specs for recording Battlefield 3 at 1080p maxed, while still maintaining 60fps average? i know the recomended system specs that the dev's posted, and i know that an i7 at 15billion Jiggawatts and 6 gtx690's will run anything i want 10 times over, but everyone has their budget. i've seen gameplay with an i5 2500k at 4ghz, and a gtx 680 can do it no problem. but is their anything cheaper i can use with the same result?
