the i7 extreme or the Xeon that is the question

SF 2009-05-13

So, I got the go ahead to get a new computer.. WOOHOOO!!!!

looked at dell, hp, lenovo, and Xi, and Xi is the winner as far asprice goes..

So now the question is, would it be better to go with an i7 965 @3.2Ghz or with the Xenon X5560 @ 2.8Ghz ?
