Quad cores, heck I was just reading about the current 8xcore bun fight between the Power 7 and the Nthalem-EX, one dual threaded per core the other quad threaded.
V7 complete if run at 64 bit will be able to keep up but its scary how fast the CPUs are growing, 8 cores times 4 threads, thats 32 threads.
Ok, true these are not due till next year but thats only a few months away.
Does Vue's renderer use the excess threads or do you have to switch off the multithreading?

Man I still remember ways back linking a couple a 2nd hand PC's together with olf V4's rendercow, my single i7's got more power now.
