I presently have an 17-950, R9-280x, 12gigs off ram Pt6 Se MB. I play BF4 and want to get a better rig. I want great game play. Can someone recommend a good system to get a great gaming experience in bf4.
With your present system the best upgrade to get a great gaming experience is to upgrade your Graphics card, a GTX 1070 offers great performance as long as you have a decent PSU the rest of your specs will be fine. If you are playing at 1080p even a GTX 1060 or RX480 will be plenty to notice a big jump in gaming performance from the 280X. Just depends on your budget and what your preference is.
Your current system should be able to play bf4 at nearly maxed settings with very good FPS. I don't know why you'd even want to upgrade if it's just for bf4.
