Intel/AMD are going dual core for their performance increase instead of
pushing the GHz bar. From my understanding chips were getting very hot with
the Hz speed increases, so instead of doubling the speed GHz-wise they
decided to go the path of dual/multicore. I've read that Intel and AMD are
readying quad core processors for Q1 of 2006. The point is performance will
come from multiple cores instead of GHz, thus you shouldn't have to pay per
core. A mental ray license cost the same no matter how fast or slow your
single core processor is.

Most important question in this entire upgrading madness is the mentalray
licensing, will a dualcore be "seen" as one CPU or will eveybody need two
extra licenses to get rendering on the two extra CPU's that are on the
dye.....

OK, dumb question again - will the dual-core processors fit onto a standard
motherboard? So if I got e.g a dual processor motherboard with 2x single
core processors, I could upgrade the procs to dual core at a later date?
(PS are opterons the better choice for XSI?)

Hm weird because the opterons were released Q2-05 , while the Amd64 X2 only
Q3-05.
I have a retailer here that just has them in (the opterons), not UK
though...
I wonder what would be the way to go,
single opteron dual core now, and add a second one later, or dual opteron
single core now, and replace the whole bunch later. the dual core cpu costs
about the triple of a single core with same clock speed...
I'm mostly interested in rendering performance.
