So is there anywhere I could find gaming benchmarks for a CPU+GPU combo? It's a fairly common combo (3570k + 7950), and I'd like to know what framerate I'd theoretically be getting for the common benchmark games (Crysis 3, BF3, Skyrim, etc.)
If you just want to get an idea of how well your system will do, Anandtech has a really great tool with CPU, GPU and SSD benchmarks. You're CPU isn't going to be bottlenecking your video card at all, so this list (for your video card) should give you a fairly good idea of how well your system is going to preform.

^That all depends on the game.
CPU bottlenecking=any time the CPU keeps your GPU from running at 100% all the time (provided you have Vsync off and no frame-limiter.) For instance, Crysis 3 seems to be incredibly CPU-dependent. And any RTS will choke on your CPU before your GPU, especially something with plenty of power like the HD 7950.
That said, Anandtech's tools will give you a great idea for how a GPU will play games with that CPU. Since they use a very similarly-performing CPU to bench with.
