I think hepsepc pretty much scales with Hz and if they are 4 real cores then 20 is probably about right for 3.4Ghz.
Adding an SSDs to a C6100 (24 threads) showed no improvement in hepsepc, and did not see any improvement in real life jobs.
There might well some cases where a high Hz cpu would be the right choice but I would still put them in a server box for space, power redundancy, ipmi.
It would be interesting to see what the hep spec of the new kit people have brought recently is though?

On these 4 core machines running 32-bit SL 6.5, I got a total HS06 of 83 => 20.75 HS06 per physical core!! This is *massively* better than any server kit we've got or have just bought and as they only cost ~600 GBP I'm wondering if I should have been buying roomfulls of these instead of expensive stuff!
