Just quick guesstimation:
my result: 15m24s=924s for each 5000 steps with 2.0G x4 cores K10 Optreon
your score: 15m24s + 6m = 1284s with 2.8G x2 cores K8 Optreon
So, 1284/x * 2.8/2.0 /y = 924
...here x is efficiency of increased cores x2->x4, and y is performance gain per core.
for example, if y is ~1.05, x is ~1.85 from the formula above...
...yeah x should be within 2.0 in this case.
In my experience for SuperPI, y=~1.05 is feasible, at least on my board and current BIOS, so far.
I don't know usual efficiency x for Folding@Home, but 1.85 looks feasible too...
