I have a MVC flashed Gigabyte GTX 770 4GB and a self flashed MSI R9 280X 3GB. I found the MSI on CL for a good price last year and bought it just to play around with DIY flashing. Both cards work great. I've been running my 770 because it has the extra 1gb of vram. According to GPU boss they weigh in about the same: http://gpuboss.com/gpus/MSI-Radeon-R9-280X-vs-GIGABYTE-GeForce-GTX-770 My question...which card should would you use? I primarily edit video with Adobe Premiere Pro CC and occasionally small projects in FCPX. I'm driving dual 27" LED ACDs. To do that with my 770 I have a DP to mDP and D-DVI to mDP adapter. The MSI card would do that without need for adapters. The only game I really monkey with for fun is SW Battlefront on Win10 bootcamp.
