Unless you spent $400+ on your video card, your FPS will always be limited by the video card, not CPU so the AMD FX-8320 will be fine. An i5 3570k would give you a few more FPS, but we're talking maybe 5% more since your bottleneck is the 7870. I assume you're gaming at 1920x1080? And not something like 2560x1440?
No, never go liquid cooling unless you go hard core custom ($$$). Those sub $100 All-In-One liquid units are waaaay more trouble than they're worth (water leaks) and ironically much noisier (fan and pump motor noise) than a well designed and spec'ed air cooling setup. I frequent www.silentpcreview.com and have based my last 3 PC re-builds/partial upgrades from their various reviews and recommendations and have been very happy. I need quiet because my PC is in my bedroom and when I need to leave the PC on to do..."stuff" overnight I need it to be quiet enough that I can still sleep. If your PC is NOT in your sleeping area, then it's far less of a concern. The Fractal Arc Midi R2 isn't bad, but I would have got a Fractal R4 for the quieter build. Granted, even on sale, it's almost double the cost of the Arc Midi, and if quiet isn't your top priority, there's a lot more flexibility in parts selection.
The first part about most gaming builds being GPU-limited is true in most cases...but then you run into something like Civilization V or DCS World that is HEAVILY CPU-limited and bound mostly by single-threaded performance, which is where AMD's Bulldozer-based architectures really suffer. Then there's the matter of emulation, if you wanna run PCSX2 or Dolphin...
Granted, most people probably don't care about such things, but for those of us that do, it's kinda frustrating when the most demanding moments really make the framerates take a nosedive and throwing more GPU power at it won't solve the problem at all.
As for liquid-cooling, I've done it over this year (bought it in preparation for Haswell, used it to cool my ol' Kentsfield Q6600 in the meantime, and both run HOT), and while the performance improvement is astounding to the point where I never see myself going back to huge tower heatsinks ever again...so is the price, as you noted.
Going by my own experience, you'll probably wind up spending at least $200 for a CPU loop with a Laing D5 pump (powerful, reliable, and quiet if mounted properly, but costs at least $70 new) and a 3x120mm radiator, probably more if you start buying things like combo reservoir/pump tops, compression fittings (which cost $4-6 each, need two for each component, and the most basic of loops will still need 6 to 8 of them; do the math), and especially quick-disconnect compression fittings if you don't want to drain the whole loop every time you change something.
The good news, at least, is that most of that equipment will last for years and can be re-used. About all you'd have to change would be the waterblocks themselves, since mounting system specifications keep changing over time. Think of it as an investment in cooling that'll pay off again and again, if you're an overclocker who likes to get the most out of the hardware you purchased.
P.S.: It's a damn shame what politics did to the development and production of your namesake.
