R9 390 vs GTX 660 Ti with i7-4790K vs i7-2700K at 1080p and ultra vs ultra settings

AMD Radeon R9 390 / i7-4790K

At 1440p, R9 390 can hit 50-60 fps on pretty much everything at ultra, just without antialiasing, less ambient occlusion and turned down shadows. It is clear that the R9 390 is a significantly more capable high-end card that can play AAA titles at 1080p/1440p with 50-60 frames per second. It is worth noting that the R9 390 is a very power hungry card and requires a decent power supply unit. In terms of memory, the R9 390 's 8192 MB RAM is more than enough for modern games and should not cause any bottlenecks.

NVIDIA GeForce GTX 660 Ti / i7-2700K

For the most part, the GTX 660 Ti is still capable of playing modern games, but you would have to reduce settings to sustain those higher framerates. If keeping graphics quality settings closer to ultra or high is important, there are a few options for upgrades. With current 2048 MB RAM, the GTX 660 Ti can have serious memory-related bottlenecks in more modern games. This combination between GTX 660 Ti and Intel Core i7-2700K @ 3.50GHz has less than 8% bottleneck in many games and is perfect match to avoid FPS loss. This combination between GTX 660 Ti and Intel Core i7-2700K @ 3.50GHz is a perfect match to avoid FPS loss.
