Sorry if this is in the wrong place but I am Just fed up with my low frame rate and crappy graphics settings so im looking to upgrade my CPU and Motherboard and was just wondering if I could get some Ideas on which CPU would be the best? I'm looking to order through Newegg and I'm wanting to get a CPU/Motherboard Combo under $300.

Ive had the same CPU/Motherboard for about 6 years so its defiantly time to update, and my graphics Card is a GTX 460 so I know its not the card causing my Low FPS its my old AMD processor...

Thanks for any suggestions :)

I've heard good things about the i5 2500k processor, but i have not thoroughly looked into it so take my opinion with a grain of salt...might give you at least a starting point tho??
