Questions about 2p system for Xeon e5

Hello [H]. Mike McCord here from MaxPC. Since you guys are the unquestioned 2p-4p builders, I have a couple questions. I was thinking about building a 2p system with the new e5-2690 for a total 32 threads. What are the team's thoughts about this proc for folding vs. the Magny-Cours or whatever most of you are currently using? Thanks for your kind help in this matter and I appreciate any input.
 
In terms of price vs performance/PPD it's absolutely terrible. For about twice the price of a 4P 48 core system, maybe slightly less than half due to rising prices in 6174 chips; you're getting around 2/3 of the performance.
 
If you have another purpose for the computer that will run better on the higher clocked, higher performance Intel cores then go for it. A 4p G34 is still the leader by a wide margin if the only use for the system will be folding but that is because bigadv is able to fully utilize such a high number of threads and not be negatively affected by the low maximum single thread performance as many other applications would be.

I currently have a 2P 2011 system (Asus Z9PE-D8 WS board and Intel E5-2680 equivalent chips) folding full time at stock speeds due to the locked chips.

The system gets ~300k PPD folding 8101's, used to get a bit more with the 6903/4 WU's. For reference, starting April 27th, I dropped my SR-2 offline and have been folding only with my D8 board. Folding stats with D8. The link shows when I had the SR2 online as well.

The cost of such a system is rather high in comparison to the overall contribution to the project, but as the other guys will share with you, a G34 system will just be a folding system, where this system is an absolute brute with any sort of other use.

Price wise, I am $600 into the board, $150 into the memory, $150 into the PSU, random hard drive, random pci-e gpu for video out. The chips are ES, so the cost is... well what it is. :p

I have used it in windows and the system is blistering fast, but I fold with it under 64bit linux.
