I could answer you fully in like one and a half month or so (that's when I expect to get my PCI version

) but about the realtime stuff. A definite "yes" to that one. Your processor should be able to do it easily, and you can even use time-shiftine realtime also without problems (as long as your disk is fast enough, wich it probably should I think unless it's old). For perfect time-shifting realtime they recommended a 700mhz processor if I remember correctly.
The thing about processor optimisations I can't answer though. It should have some optimasasions for the AMD processors (if thay were smart), but I can't really say for sure. The speeds may then vary a little in the worst case, but nothing to drastic (I hope).
