What OS and codec are you using? If you are using the NV Purvideo codec and are comparing an ATI based board to an NVidia based board, then that is why it is likely doing a lot better.
Also, to the boost in RAM, that is a good idea. Where the onboard video gets its RAM from system ram, I would not run with less than 2 GB so one can go into the BIOS and assign a large amount of RAM to video and still have at least 1 GB for your OS.
And to the experience with a lesser CPU, how much lesser was it? If it was only a couple hundred MHz slower, that is trivial. If it was say X2 3600 vs. X2 5000, well, then I would be confused.
