Okay, so I managed to successfully install the GTX 680, but as you can imagine, I can tell my processor is holding it back.
What kind of processor can I get which runs with my motherboard (Model: ga-ma78lmt-us2h from Gigabyte if it matters) and won't hold my graphics card back?
You're not going to get anything much better sticking with AMD, just ride it out and save for an Intel upgrade. The only thing I'd say would be worth getting now is an 1100T, but there'd be no point as it's such a small upgrade from the 965
