Well the 2500pt cap obviously handicaps the gpu folders and gives the edge to the smp folders. I think that people fail to see that it involves a lot more work to rack up the points with smp. VMware, which many people run, is more susceptible to errors and problems. SMP projects take a lot longer than gpu projects and if one of them were to fail, half the day would be lost.
I'm basically saying that there is more work and more risks involved with SMP, thus the rewards are higher.
Most gpu's in the competition can reach 3k on a daily basis, specially those who use multiple cards under their competition name.
I think that 3k would make it more interesting and in order for the CPU folders to dominate, they would have to run flawlessly for the entire month. One little mistake or a couple of bad days has the potential to drop them out of the lead. The downside is, that it would take anyone out of the competition that doesn't fold on a high clocked dual core.
If there is a cpu folder who completes 2-1-2-1-2-1-2-1 ... in 30 days they would max out at 86,400 give or take a wu or 2 depending on what they start off with. A gpu folder would hit 90k if they had a 3k cap. This is assuming that the cpu folder would only get the 1920pt wu's. If there are some 1760's thrown in, it could easily drop output by a huge amount.
I don't know where I'm going with this, I just started typing stuff.
