A single core K8 CPU like the Orleans core (F revision of K8 ) can run unhurt for years @ about 2.5-2.6GHz on stock cooling, especially if your Vcore does not get past 1.45V and that will have a beneficial effect on your framerates; so:I currently am using AMD 64 3200+ Orleans socket 939 overclocked running 2.2 GHz, is there a better card out there that I would notice a difference if I upgraded?
It can not be 939 if you are using ddr2. It has to be AM2. Also the Orleans is an AM2 core not a 939 core. That is a pretty good card and will definitely show improvement in gaming. I would also recommend getting some better ram as well. DDR2 800 is what you really should be running and 2gb of it would help a good deal, especially with WoW which really seems to shine with 2gb of ram and a decent midrange card. I know my system has no trouble with WoW at all. Download CPU-Z and run it. Then do a validation and give link. Then we can determine for sure what it is you are running. Here is my validation from my system as an example.

Cpu-Z and other programs quite often do not read 8O spec correctly.CPU-Z can be wrong at times. It once told me that my friend's Willamette P4 was running on a VCore of 0.020V, which is obviously impossible.

This link would be for your processor if it is the Orleans core. Note how it says it uses AM2.
