Biggest difference is that the 990FX has more PCIe lanes and can SLI/CF cards with 2 slots running at X16. The 970 is perfectly fine for most especially if only 1 GPU is involved!
That's kind of what I thought but wasn't sure. So with a 970 chipset or therabouts, will I still be able to OC a little bit if needed? In other words, is the 990FX chipset required to do any OC'ing at all, or will I be able to OC somewhat with a 970? I'm learning as I go here so pardon the noobishness.
