We have to order a new designer workstation for a user that use Mastercam X3.
I had a quote with a QX6850 cpu but it seems that the hardware is no longer available so I have to setup a new system.
My choice of cpu is: between the W3520 and the E5520 (90$ more then the W3520).
I read that the W3520 was an earlier nehalem base version but the clock speed is at 3.2ghz while the E5520 is 2.26ghz.
So is the E5520 truly worth more then the W3520 speedwise?
I'd hate to pay more for something that works slower.
Also, for the memory, would you suggest ECC or Non ECC memory? I beleive the ECC memory is slower because of the error checking, but does it work better for designers? I could understand in the case of a server...
Thank you,
