Well, your 3DMark scores are right in line with mine, so it looks as if the 9100 is working just as it should. If there were some driver conflicts or if the settings were off, then most likely our scores would be remarkably different. I don't think getting a bigger PSU would help. It runs just fine on my 180w Dell PSU.
Have you tried playing any other games besides MOHAA? I noticed that Neverwinter Nights plays kind of sloppily on my system whether I'm using an Nvidia or ATI based PCI card, whereas Dungeon Siege plays pretty nicely.
One thing you might try is to go into the MOHAA game options (most games have an option where you can alter the video settings in-game) and look to see what level of quality the video settings are set to. If you see anything that says AA or FSAA or AF (usually with a number and multiplyer designation, i.e. 2X, 4X, etc.) and they are enabled, then turn them off. Also, play around with the detail quality settings in the game and see if lowering or raising them has any effect. Another thing to try is to turn off shadows, or shadowing, because that takes more video card power and turning them off usually leads to better framerates.
I don't know if you can do this in-game or if you have to do it in the control panel display settings, but try turning off V-sync. That sometimes helps framerates, as well.
Now, are you getting the horrible MOHAA performance while playing single or multi-player, or both? If it is only multi-player, perhaps the problem is not with your video card, but with your internet connection. If you're playing multi-player, are you on Cable/DSL or a dial-up modem? Sometimes "lag" is a problem with multi-player games, especially for people using dial-up. Lag can cause severe choppiness in gameplay, too.
One other thing, at what resolution are you playing MOHAA?
EDIT: That guy, Greesman, at the Dell forums had to go through 2 faulty cards before the 3rd card from CompUSA actually worked like it was supposed to. However, his problems were not with video quality, but with major crashing in general. If we can't figure out what the problem is, is it possible you could return the card for a replacement?
