OK, this is probably a stupid question but, other than live migration with my existing Intel based host, I have a choice of two spare machines for a second host.
1st: AMD Dual twelve core processors running at 2.2 GHz, L2/L3 - 6MB/10MB, Bus Speed - 3200 MHz, 1333 Mhz Memory Speed. (Dell R715)
2nd: Intel Dual quad core processors running at 2.66 GHz, L2/L3 - 1MB/8MB, Bus Speed - 6.4 GT/S, 1333 Mhz memory Speed. (Dell R610)
I thought I read somewhere that the AMDs didn't necessarily perform as good or better as Hyper-V hosts.
