I have a Antec 650 Neopower psu and was wondering if I should go bigger when I switch to the Q9450 cpu? You can see in my sig what I'm running at the moment as far as other components.

Unless you're overclocking the processor and RAM I wouldn't be concerned with your 650w.  The only thing you need to be aware of with the Neo series is how much load you're putting on each rail, as you have power loss through the removable molex and SATA power connectors, as well as your PCI-Express power connectors. So in other words don't overload too much on one side as I did.  You'll notice stability problems if you do this, been there and done that.

I am going to be oveclocking so I think I'll look around for a higher watt PSU. Anyone have some recommendations?

If you want what most consider the best PSU out there go with this one:

 PC Power & Cooling Silencer 750 Quad

 From Anandtech's Review

"The AnandTech Gold Editor's Choice award goes to the PC Power & Cooling Silencer 750 QUAD. It was one of the first units we reviewed in 2007, and remains the best overall power supply we've tested. In addition to top-notch performance, the Silencer 750 QUAD is equipped with a full range of connectivity options (including four PEG connectors, two of which convert to the 8-pin standard), and ample wattage for nearly any high-end system, including SLI or Crossfire configurations. As a nitpick, we found that the Silencer 750 QUAD's fan speeds may ramp up more aggressively than necessary; under worst-case conditions (50°C intake temperature), the fan did hit 4200rpm, resulting in noise levels of 45dB(A). At normal room temperatures, however, the Silencer 750 QUAD did not exceed 30dB(A) at normal loads."
