Really the E3? Thats brand new out and quite expensive. We were looking more along the lines of the E5520 or E5620 but couldnt decide if we needed just a single processor or two as we are currently running 2 x 5405's in our servers but then again they dont support HT.

Actually the E3 is very affordable.
E3- 1230 is a better choice then 1220 as it supports HT
E3-1240 is slightly more expensive but gives good value for money
E3-1270 is a good choice
E3-1280 is relatively expensive. Not recommended at this point until price drops.
Woops! Was thinking of the E7, my bad. So you would go with the E3-1270 over 2 x E5620's? Or should I go with dual E3-1270's?
Dual E3 is not possible. The E5 will be dual CPU but its not out yet. The E7 is already available and very impressive! quad cpu boards make these CPU's are good choice for those that need a lot of processing power.
I would wait for the E5 or go for 2 servers with each a E3-1240 or E3-1270
Some E3 mainboards also support SATA3, another benefit of the E3 above the older Xeons.
But if you cannot wait and need nodes with a lot of ram, 2 x E5620 or 2xE5650 (5650 has 6 cores, 12 threads each) is a good choice as well.
Since your original question asked comparison between i7 and Xeon i assumed you wanted a comparison between either the new Sandy Bridge range or the older i7 / Xeon 34xx range.
There are no dual i7 setups. i7 counterpart is the Xeon 34xx also a single CPU setup.
I am just trying to come up with something that wont bust my budget but will also be a good fit for the vps node I am building. Like if 2 x 5620's is overkill, would the E3-1270 be more then sufficient? We run 2 x 5405's with a little over 30 vps's on our node and the load is never above 5.
Yes the 1270 would likely be sufficient. 5405 is three generations older and your load of 5 would mean that 5 cores are loaded, you got 8.
By the way: the E7 is already available in quad CPU setups. They are extremely fast.
