That was my guess. It looks like it should do what you want....and it has room to grow.
The onboard Video, will be better then what you're used to....But the MX line...doesn't have all the pixel and vertex shaders, that make all the good eye candy. The prices on Geforce 3 cards is still going down and should really drop when Nv30 hits the shelf. (I here its been pushed out till Feb) A friend of mine had a GeForce 2 MX board in his dell...I just upgraded it with a Geforce3 Ti 200, I picked up for 63 US. His benchmark score went from...4023...to 8098...
He loves it..
I also left him with my, loaner copy of W&W...I think he's hooked.
