hi I want to build a pc that will be for hosting virtual machines. Its going to be a test development pc.

I need it to be x64 and have about 8gb of ram.

But the problem I am having is deciding what cpu to use.

I want something that will last a few years but is not too much overkill.

Core 2 Duo 3.06ghz looks ok but i dont know if that will be enough.

Intel Core 2 Quad 2.83GHz maybe wasted for what i am going to use it for.

I,m not going to be running virtual machines all the time and when i do its going to be a maximum of three open at a time maybe.

So thats host plus 3 virtual machines.

What do you think would be the best cpu?

thanks

Did you mean the C2D E7600 3.06Ghz or C2D E8500 3.16Ghz?
E7600 doesnt have Virtualization Technology Support like the E8500 or Q9550.
E8500 or Q9550 - either one would be a good choice.

thanks I see now.

so E8500 & Q9550 both support 64bit and virtualization.

I am running an i7920 at the moment with 6gb DDR3 on my main machine. The cpu sits at about 2% at idle and goes to about 12% max under load lol.

I want this to be a development pc and dont want to overkill the spec if you see what i mean. plus i want to keep the price down lol.

I,ve only just finished paying for this dam i7 build lol.

If you're going to be running cpu intensive tasks on the vm's then get the quad. If not, then the dual core should work. But, I would get the quad.

Newegg has an quad core opteron am2 75w for only $74.99 plus shipping. You can use a gigabyte board with it. Gigabyte boards bios will recognize opterons.
