Interesting you should say that...
I had a desktop running two 9800's in SLI and Morrowind didn't support it, so all the mods caused it to run waaaay too slow.
Now that I have a GeForce 550 Ti, I can run Morrowind and the texture/remodel mods in PlayOnLinux
I'm sure it would run if you crank down the resolution and some of the settings.
Just have to trial-n-error the mods.
I can make a list of Mods I was using in my guide
