I think i would save a little on RAM and PSU and get if you can a 7950 (its a little faster than 270x at stock and it OC prettry well. 1100/1550 mhz almost guaranted) for just a litlle extra you can get real close to hd 7970 numbers with an extra 1 gb of gddr5. I would choose an i5 for CPU if you like starcraft the cheapest one you can find. Or put a K variant an OC with an aftermarket cooling but its way more expesive. Go fx 6300 route an save a little money or go i5 its my advice (dont know if fx 6300 issues on BF4 have been solved, only game where 8320 its faster than 6300 by a decent amount i think)
Get a 1080p monitor or better for an improved experience.
