i7-920 v. Xeon X5550

[idata]

Hello,

Perhaps my question is too simple. So, my apologies for its simplicity.

However, what is the performance difference between a 2.66 GHz 1366 i7-920 processor and a 2.66 GHz 1366 Xeon X5550 processor? Please disregard the fact the X5550 is meant for a dual system. I'm trying to weigh up the reasons to build either an i7 2.66 or a dual processor X5550 for my photo processing work.

If there is no performance difference, then am I correct to assume that adding a second Xeon processor will not aid performance if I am running solely a photo processing programme (ie Adobe Lightroom or some such programme)?

Many thanks for the help.

Mark

ps I run Linux - Suse . 11.2

The Xeon has more turbo than 920 (920 is 2,1,1,1 and X5500 is 3,3,2,2 (for 1,2,3,4 threads))

If Lightroom won't use 16 threads well then it's not worth having the dual system, a X5500 is $958 RRP, vs $999 for W3580 or 975 vs $284 920.
