We used the E5-2620 series since v1 and now it gets two additional cores for the same price.
However when it comes to CPU's the price was really good for a while now, hopefully the prices for SAS drives will soon be as good as CPU's aswell.
I mean computing power is propably cheaper than storage at the moment.
It depends on your DB workload ;)
Actually we sell the 2620 for shared nothing architectures to all kinds of small to midsize customers.
If you don't need to run fast queries against your analytics or keep logs for something like 20 years you really won't get too much data. Especially when the only thing you index are the content of business documents.
