added khash/W and khash/GHz
all x5650 line and v1 xeons have same khash/ghz = about 4.2
all v2 xeons same about 4.65
does not matter if it is 24xx or 26xx line
so you can easily compute hashrate for any cpu
. best v2 xeon e5 2697v2 will have ~670khash/s and 2.57 khash/W
v1(or x5650) vs v2 xeons is only 10% difference, so if you have cheap or free electricity, you can save money and buy g6/g7 servers, they are really cheap, dual x5650 machine for ~100$

more machines coming soon...
also i will do test linux vs win on same machine
