Are you getting the best from your graphics video? EVGA's Precision is a versatile overclocking utility that will fine-tune your video card for the maximum possible performance. You're able to tweak your core, shader and memory clocks by dragging a slider. It's possible to create up to 10 profiles with different settings, and you can even assign hotkeys to them for instant switching. In theory, Precision is for EVGA 6, 7, 8, 9 or 200 series graphics cards only. But in practice, we've found it works on other GeForce cards, too: when RivaTuner wouldn't overclock our BFG GeForce 8800GTS, for instance, EVGA Precision stepped in and did the job very well. Just keep in mind that this isn't supported, and there may be a risk that Precision will adversely affect non-EVGA graphics cards.
