Core i7 920 to Xeon E5540 ES

I have changed a processor on my main computer to Xeon E5540 ES (2.53 GHz). I have received it from USA for a quite low price (I sold my Core i7 920 for the same price). The main purpose to change it was some curiosity to have an engineering sample and a lower TDP (which is 80W instead of 130W on XEON). What is more Xeon is workstation/server CPU which suits me more. I has a little lower clock rate (2.53 instead of 2.66) but faster QPI than (5.86 GT/s instead of 4.8 GT/s). You can find two scans of it in my cpu collection.

Update (2012-05-08):
I removed images from cpu collection album in webpicasa as I don't have this CPU anymore.
