Hello everyone,

I'm thinking of building secondary PC system for Monte Carlo simulation and similar analysis and thought crossed my mind why not buy some "cheap" old LGA2011 double CPU socket motherboard and pair it with two old Xeon E5-2670 2.6 (3.3)GHz processors, rather than buying new i7 or Ryzen. This way I could get 16 cores, 32 threats system, for a fraction of a price of a single i7 6950X CPU system and also considerably cheaper then single Ryzen 7 1800X CPU rig.

Where is the catch/drawback? It sounds just too good to be true. Am I missing something?

That is good question. I guess it will be good for two or three yrs, it maybe OK for 5 yrs, but I think nobody will know. Keep in mind we know the games don't need more than two cores before, but now the games will need 4 cores or more. Time will change everything.

Also like the i3 6100 and the Pentium G4560, the i3 was released about two yrs ago, the Pentium G4560 can match up with the i3.


First gen e5's are even when with 2 are beaten by the new ryzen 1700. It really depends on what generation you are getting. Also lga 2011 boards that do dual cpu are expensive (200$+ minimum on ebay). You need to have a motherboard that can at least do the v2 e5's. This will easily 250+. Then at least 50$ for each cpu. Then at least a hyper 212 (2*30$) and so on. Eventually you will get good performance but at the same time for a bit more you can get a ryzen setup that performs similarly and is newer.
 
Thanks for the url cin19. I see that dual Xeon is actually faster than Ryzen 1800x in benchmarks that matters to my work. Do you think buying 5 years old CPUs is a gamble or they should work for at least 5 more years?
