This is what I don't get. I did upgrade my card to something a little better. GT220. And I am having the same issues. It is making me wonder if something else is going on. I have an AMD x2 4400+, 4GB RAM. Power supply is a 400 watt. Not too far off from your specs.
In Windows XP I can't get the FPS past 60, even with all the video effects at the very minimum. In Vista with Aero off, I can get an average of 70 FPS with everything on except Shadow and Water effects.
In Wine with everything off it hovers around 20-30 fps with all effects off. In Dalaran it is in the upper teens to low 20's with everything off.
I am completely lost on this. It makes no sense.
Edit: With glxgears I am getting:

These numbers are a little more then doubled with what I was getting with the 8400GS. But I am still getting the same ingame frame rates when using Wine and WoW with the GT220 as I did with the 8400GS.
I can't get a GT240 or higher since my computer does not have a PCIE 2.0, so a GT220 is all I can do with that. But like I said I am thinking it is not the Video Card that is the problem.
