The Q6600 outputs about 90-120watts overclocked and under extreme load. Probably about 85 or so normally. Your current processor outputs 65watts max. Most likely not.

Sorry, when I said "most likely not" I meant you wouldn't have to upgrade your PSU.
Sorry for the confusion.

Judging by the pictures on the internet, yes. You'd just have to make sure that it (the new one) is not too large.

So far I was not able to find confirmation about Q6600 in 745 USFF, I can guarantee Q6600 working in Optiplex 745 SFF, however there is problem with power supplies - 745 SFF has 275 watt PSU and 745 USFF has only 220 watt PSU, this can prove fatal.
The only upgrade most likely to work here is E6600, PSU upgrade is not possible here, at least I did not see one yet.
Also, USFF doesn't have PCIE slot, just FYI.

An Optiplex 745 will run a Pentium D (95w to 130w), core duo, or core 2 duo 1066fsb, or core 2 quad 1066fsb.
The quad core ships that will run are the Q6600 and the Q6700 (105w each). I've done both, they work well (I ran them in full towers)
I would not recommend running the quad core chip in an ultra small form factor case for cooling issues and because you have a 4gb memory limit (2 memory slots) and no good options for discrete video. I would get a 745 tower if at all possible. Then you can run a quad core and up to 8gb memory and most importantly, not worry about cooking your PSU or the capacitors on the motherboard.
If you want to beat around the Internet and run office apps, stick with the 745 USFF run a core 2 duo 6400 and win7 32bit with 4gb memory.
If you want to do more, get a 745 tower, max the memory, upgrade the PSU, and get a decent gaming card and you can run photoshp, game, etc.
If you need the space and want to get crazy (and have an unlimited budget), get a 755 USFF and run a core 2 quad 9550S. You'll still have that 4gb memory limit but it will go real fast and stay at a 65w

If you have USFF, you can not upgrade video card, because you don't have PCIE slot on motherboard, PSU is also proprietary and can not be upgraded.
Also, lysinger was talking about SFF and MT models, not USFF. USFF has different motherboard, hence the limitations!

Unfortunately for USFF owners not much, as I stated above, small upgrade in CPU is possible, but not to the QUAD. Also, if you can not install Video Card, what would be the point of your upgrade? It would be good only for office use, not for pleasure!
Sorry to bring you the bad news, but it is true - I really searched Dell forums for answers and nothing positive, general information doesn't apply to Dell PCs!
