and have had some slowdowns in a few graphic-heavy games recently, specifically Crysis 2, and was planning to overclock my CPU a tad.
Well overclock controls in this mobo's BIOS are almost non-existant. So I was wondering if I'd save more in the long run by getting a better mobo, as opposed to upgrading my CPU? Does anyone have any recommendations on a motherboard?
Welcome to Tom's Hardware.
You will get a much better performance increase putting your GPU in SLI (another GTX 5xx) than simply OCing your CPU or replacing the mobo - gaming is more graphics intensive than CPU intensive. Check your mobo manual though to make sure SLI is supported before buying another GPU if you decide to do that.
