Nuxley did you not think about going AMD64bit way?
You could have covered yourelf for the near future.

"When 64-bit technology matures and catches up software wise gamers, artists, musicians and those doing professional graphic such as CAD and MAYA will be in for a treat as realism will be more visually realized in the 64-bit environment. I think AMD deserves credit here as this is one bold move on their behalf and shows the direction of the company changing from a here and now attitude to one of looking toward the forthcoming future leaps of technology."

Good read comparing P4 with G5 and AMD64FX...
