I've been steadily upgrading my computer into something of a behemoth. It came stock with an AMD FX 4130 quad core processor. This is a decent lowish end processor for gaming. Would I see an appreciable difference in performance putting in something like an FX 8350?
Well there are several ways to diagnose your situation, but I would need a bit more info about your rig, such as the GPU, power supply, and whatnot.
The AM3+ platform is pretty good all-round, and keep in mind that the most important thing for gaming is the graphics card, always. But, bottlenecking can happen on the CPU. Usually though, the CPU only starts bottlenecking with dual-core or single core CPUs, and the 4-core FX has a high enough output per cycle to keep up.
The best way to tell is to mildly overclock the CPU, for about $40 USD, you can get a very nice aftermarket cooler that will help with this. I usually recommend this anyway, as AMD stock coolers are. . . bad.

Make sure this will fit in your case, of course, and there are other options out there, but I think this is a solid choice.
Edit:
Ok just saw your second post. If you are worried abut overhead for recording, then there are several other angles to this:
1) Fraps is great, but its files are very large, and most people bottleneck at the write speed of their Hard Drives. An SSD is strongly Recommended for fraps use. Cam studio and others are less HDD intensive, but also can be lower quality.
2) External or PCIe capture cards can be an option as well, as their overhead is moved to the PCI bus.
3) For free, you can try MSI Afterburner software. At its core, it is overclocking software, but it also comes with video capture and voice recording. I have not used that function myself, but it is free, and may be worth a try.
