Okay. For one, the PPC 7400 chip is not based off the PPC 750 chip. It was based off of the PPC 604 chip, and the PPC 750 was based off the 603.. Reasons why AIM (The PowerPC Alliance... Apple, Motorola, and IBM) didn't decide to just use the 604 when making the 750 are unknown to me. Probably dealing with Price/Temperature concerns. AltiVec is not your ordinary add on to a processor. Unlike MMX, a program can be optimized for AltiVec with a single click of a checkbox in Codewarrior, yet still run on machines that do not have AltiVec. The Floating Point preformance has been at least doubled on the chip, and with the addition of the vector unit (which normally has only resided on high end supercomputers), this processor has really shown the others up.
Oh yeah, don't be stupid anymore... all PowerPC processors are 100% RISC. Always have been, always will be.
The only problem is, Dreamcast is out NOW and Playstation 2 is out in a little more than a year. Thats kinda like comparing athlon to the best x86 processor a year before it athlon was released... Kinda stupid. And Dreamcast has one advantage right now. Sega has the most Launch Release titles out of any system in history with the Dreamcast, more than 15 games will be available in the first week. N64 only had 3, and Playstation had like 5-6. PSX2 is still a year and a half away, video cards and computers will come a long way in that year and a half, so just keep your socks on.
