At the moment, I've got quite a varied selection, as follows:
Dual Opteron 265 - VMware 2 x Linux SMP + 1 single client
Dual Opteron 242 - Win SMP
Quad Xeon 900 - 4 single clients
Core 2 6300 - VMware Linux SMP
Athlon X2 3800 - Win SMP
Pentium 4 2.8 - 1 single client
Athlon XP2500M - 1 single client
That gives me about 4000-4500 ppd.
But I've just received the last part of this lot today
for my new farm (as well as an upgrade to my Home Cinema PC).
I still need to pick up some better coolers before I overclock these new crunchers, but that can follow on once I've got them all up and running.
The sad thing is that I'm working abroad for the next few days, so won't be able to get them crunching till at least Friday at the earliest.
I'm also on the lookout for a new server motherboard as I've just bought some Opteron 265's from eBay (some to upgrade the 242's and some for a new server) which should materialise in the next couple of weeks, to complete the upgrade process. The P4 and the Athlon XP will then be going into retirement, probably via eBay to recoup some of the costs of the upgrades.
Should get my production up quite a bit though, close to 20,000 ppd with a bit of luck and a following wind.
