2500 is a good bet,... may get up to 2700 if real lucky,... though graphics card won't make a difference,... ram will to some degree,... case will as well,... personally I would save the aftermarket cooling and expensive ram and set goals at 2400 - 2500 because you will spend $100+ on those and may not even realize any more gain anyways,... stock cooling on the 3000+ will get you to 2400 or more without heat issues,... if you want higher then spend $20 more for a 3200+ and that will get you 2500 - 2600 approx without issues and still save $$$
