I currently have a EVGA GTX 950 FTW card and a 1080p monitor, I was looking to upgrade to a 4k display but don't think the GTX 950 will handle the 4k that well, I have seen benchmarks of the GTX 1080 at 4k and the FPS is not that much better then what I get now with my GTX 950 at 1080p, so is it that much better to upgrade? and is it worth the cost?
