I wouldnt try and setup a SMP client like that. The unicore client will do that but wont net you the kind of PPD a SMP client will.
The unicore client doesnt receive bonus points like the SMP client does.
Lets see if i can explain from my limited knowledge. The SMP clients run a special kind of scientific WU that has great importance. The Scientific WUs are more more intensive and because of the importance they have a limited time frame to fold. (i believe its 48hrs) and you have to maintain 80% or higher completion of WUs on time and without errors in order to receive the bonuses.
Running a SMP client is almost like running prime 95 24/7, and thats no joke. You have the ability to set the percentage of the CPU used. Never set it to 100% if you are also running GPU clients on the same rig. This is because the GPU clients also use a small percentage of the CPU, and if the SMP client is using 100% then it slows the GPUs down to a crawl. 85% is what i set mine to so they arent maxed all the time.
Heres the break down on how the SMP client folds on my CPUs.
i7 920 is folding at 1% every 5 min, Q9650 is folding at 1% every 7 min, Q6600 is folding at 1% every 8 to 9 min.
Phenom 955 is folding at 1% every 9 min, Athlon 64 x 2 5600 + folds 1% every 21 min.
So you see a good cheap quad core is the way to go. But the Xeons are monsters at this kind of work.
If I got offered a deal like that I would fall all over myself getting it. LOL
