Well right untill now Nvidia kicked ass
But looks like the GF FX is total crap

so yeah my next buy will be an ATI most likely. My next card should be the one that will allow me to use the best FSAA and Anisotropic filtering settings at a playable speed of course like 60FPS
Ok now going back to the topic. I have found a way to back up those games I believe...
Anyways instead of copying right from the CD to my PC. I used HDD Loader 1.0a and copied the games to the Xbox HD one by one since I have the retail HD only.
Once the game was copied to the HD I tested it from the HD and it worked great. I then FTP it to my PC and burned it with the DATA burning method and viola...
Spider-Man works

Rallisport Challenge works
So my guess is that the others should work with this method as well.
I don't know why they were giving problems with direct file copy from the CD to my PC HD though.
