Dell Optiplex 755 (Midtower) E7300 Core 2 can I upgrade to Q9300?

[leasure23]

My work PC is too slow for the programs I run. I do Computer Aided Design and use Solidworks, Auto Cad and the multitude of other programs. I got the okay for an upgrade but it has to be pretty cheap. I found a Q9300 for just over $100.00 and was wondering if if I can switch these CPU's with no issues. I plan on making sure my BIOS is up to date before installation. Any foreseeable issues with this upgrade?

From this resource, it appears you should be good with the Q6600, Q9450, and Q9550, and Q9650. The Q9300 should be fine also, but not 100% positive. I would be concerned about the small power supply if upgrading the CPU and other components. 280W - 300W is what they reference...
