I'm going to buy a used workstation, options are dual x5675 or a single e5-2660 v2
and 32Gb Ram 1600 and quadro k4000. the work is mainly architecture visualization 3ds max and vray rendering.
Consider the release date of both because it is used parts and the technology difference.

Theoretically 2 x X5675 will have more threads i think 24 and higher clock speed while the 2660 v2 have 20 threads and more cores .
I think 2660 v2 is better but i want to make sure for final decision.

V3 CPUs don't use the same motherboard as V2. Z800s are bulletproof. You do HAVE to use Windows Pro on a dual socket host.

I don't have a strong feeling either way.

The dual CPU has more cores (total) and higher clock speed. The E5 has more memory bandwidth. It is older, but clock speed usually wins. Single thread performance is similar so the dual socket should do what you want faster. The E5 motherboard may be dual socket and you may be able to add a second CPU.

If your E5 choice can be upgraded to a second CPU then I would go that way. The X5675 is pretty much maxed out.
Better immediate performance is the X5675, the E5 may have longer term upgrade potential.

For performance we are talking about "rendering" in VRAY, would it be a huge difference ?
I am choosing the E5-2660 V2 because it is newer generation and also the motherboard is newer. Also if Iam getting the E5 it will be a single socket machine not dual, "Dell T3610"
if I go for the 2 x X5676 i have these options "T5500, Z600, Z800" but older versions not the new ones...They are customized depending on the need.

A dual E5 would be better I know but it is out of my budget for now.
I think I could get this single socket "T3610" and in the future upgrade to a higher E5-2600 V2 or V3
Thanks for your reply!
