Nothing major, but it'll depend on the game mostly. Minecraft, Starcraft 2, GTA IV, yeah, the CPU will bottleneck a bit. Witcher 2, modded skyrim, Crysis 3, the GPU will be what's struggling to keep up. Basically as much balance as you could really hope to get.
I have almost identical build(less ram, HDD and different case+PSU) and I havent find game(even ones you listed) that doesnt run 1080/60fps, though I do have my CPU OC'd to ~4,5ghz.
Only thing that doesnt run all that well are dolphin/pcsx2, but I really dont care since I own both consoles anyway.
