there would be a measurable fps loss compared to much higher tier cpus... but the difference would be negligible. you still would get very high quality 1440p gaming out of the rig, obviously near the max possible experience at 1080p. like others said, overclock that fx6300, its fairly simple. that said, depending on your gaming, especially if your happy at 1080p, you might be just as happy with a gtx760 or r9-285, their prices should be coming in right at $200 soon enough with the gm204s pricing. that would still be a solid 1080p gaming rig for a couple years and by then we should have a new amd carrizo, intels skylake, nvidia pascal and amd maui gpus, and affordable 4k monitors.
