Looking for a CPU upgrade, at reasonable cost without spending a fortune. Currently have a Q9450 2.66Ghz. The rest of my components including Mobo are good spec (Prostar T series Mobo), 4Gb ram etc. I'm totally out of touch these days with what's out there. Can anyone recommended a CPU that's going to give me a noticeable performance increase across all functionality (graphics, gaming etc) without like I say spending silly money. By the way this is for a SFF case, so no room for a massive cooler, and want something that runs nice and cool.
