I haven't built a system in about 2.5 years so I'm a little behind in the newest Mobos, etc.
The system will be used as my primary work computer and I need to do testing using virtual machines with Hyper-V so I obviously need a lot of RAM and would like an SSD as my primary drive for boot and programs. The processor can be a mid-range i7.
Any recommendation for any of the components would be greatly appreciated.
Also note, Sandy Bridge will be out by December. You may want to consider waiting. HOWEVER, I don't think you will see any Sandy Bridge server boards (esp. 2P)/CPUs for a while so you may build now. It's up to you.
^ No. The only reason I used the Xeons is because it is needed for 2P set up.
If you are running a 1P set up, there are a few advantages to Xeon such as the ability to use ECC RAM. That's pretty much it. In every other sense, they are the same thing as i7s except a bit higher binned (read: usually use less vCore).
