My lowly AMD Athlon XP 2000+ backend does (simultaneously):

Record 2 SD programs from 2 PVR-150s
Reocrd 2-4 HD programs from 2 AverMedia A180 HD cards on QAM from Comcast
Commflag up to 2 HD programs
Stream one HD program to my remote frontend

and it does all this on a machine that cannot play back any HD stream for
viewing on the local frontend.  In your case with the frontend local, you're
going to have CPU problems.  The only things that really consume CPU on my
list is commflagging (and playback of course).

btw, I really like my AverMedia A180 cards for HD
