E5-2603v3 for GPU folding rig ?

Would you guys agree that a Intel® Xeon® Processor E5-2603 v3 (15M Cache, 1.60 GHz) Specifications would be a good choice to drive a 24/7 GPU folding rig ?

I aim to have a maximum on PCIe lanes to not be limited. I would not expect CPU folding on that rig; but the CPU should be busy with Linux as host OS and Windows as guest (both to fold with x16). Eventually two higher grade GPU and maybe a low energy one to fill the space.
On a yet to be decided X99 board.

To slow CPU ?
 
Pretty good question. Not sure for folding, but I remember when the 980ti was released, the gpugrid community did some tests and the conclusion was, in my memory, that 3 GHz was a requirement for the 980ti, against the usual 2,4 GHz requirement.
 
I'm not sure, if you can wait a couple of days I can do some clock speed testing on my older xeons.
 
Oh yes, no pressure right now; just looking ahead and want to get something better for virtualization (where get you all the chips from ??):eek:
Basically I'm interested in the low-watt/low-price but 40 lanes.
 
OK, I've ran a test on the following config:-

Sandy based E5-2665 configured at 1.6ghz, no turbo, 6 cores and no HT. 15% in and PPD on my 970 is identical to it running at 2.4ghz, turbo and 8 cores running with HT so no problems there. However if you are think low wattage you may want to consider a different cpu, the 2603 has a max tdp of 85watt, there are others out there but they will cost more £££.

I've started a low power project of my own but its on hold as I've just had an unexpected bill in the shape of new glasses. I'm going socket 1150 running a E3-1230L cpu. If you aren't in much of a rush I'm hoping to finish the build in the middle of next month and seeing what that consumes and produces vs my current gpu rig based on the above E5 and a Z9PE mobo
