RSX wasn't a bad choice, it puts the PS3's straight up graphic capabilities very close to the 360, then with proper programming leveraging the Cell to actually allow superior graphics, while still maintaining an equal or even better game environment outside of the graphics. Either way though, it's not as easy as programming the 360, but from what I've heard, was no where near the pain it was to learn how to use the EE back on the PS2 early on.
