Hello, I am currently sporting a GTX 770 that I got back in January. Since then it has worked flawlessly. My local micorcenter has a open box Asus DirectCUII R9 290 for $400 and I was wondering if I would see any difference in performance and/or it would be worth the increase in performance. I am playing BF4 at 1080p and a 4770K. I also use folding@home as well as GPUGrid on BOINC. I figure I can sell the GTX for 280ish and pay for the difference. Just not sure if it will be worth it at this point. Thanks!
