the r9 280x is the best choice. More vram for futureproofing and gaming. the extra vram in future could help it stay playing at ultra-high longer also their just as strong as each other so no need to get a 50 euro more expensive gpu. How much is a r9 290 if its the same price on near the same price as a gtx 770 go for the r9 290 it will provide best performance.
