I verified it today.. The only thing that you need for a program to work on a dual core is SMP support. A lot of programs have SMP support but its all about how its coded in. Some programs are designed for use on dual processor systems, these programs (nuendo for one) will not take advantage of dual cores because they do not have LEGITIMATE smp support. However, if i pull out one of the chips (only 1 275 remaining) nuendo will use both cores of that single processor. A good example would be the windows xp 64bit extension pack.. Although the extensions allow for 64bit programs to be ran it isnt a legitimate 64bit operating platform.
Anyway.. i took screenshots of some of my benchmarks they will follow this post.. I haven't done any real application testing yet other than nuendo. I was going to load up quake 3 (i was told its supposed to have SMP support), aswell as the 64bit version of farcry (going to install 64bit 2003 server on the system tomorrow).. Although im unsure if farcry has smp support or not, i assume so ... we shall see.
