Intel's new Sandy Bridge 2600K at 4.9 GHz on a Corsair H50 did p6058 in 2:04, 31,000+ ppd. That's 33% faster than an i7 @ 3.8 GHz and nearly 72% more ppd. Extrapolating to -bigadv, it's going to make frames on p2686 of about 23:00 for ~56,000 ppd. Scale it up to 6 cores and put two of them on a SR-2 class motherboard and you could expect 8:00/frame, ~272,000 ppd.
