Really depends on what the vms are doing, and what OS they are running.

Can you turn on hyper threading in the BIOS? That CPU is a 2 core 4 thread which will help out tremendously with VM's

I have 3 running from my low powered AMD 2.2 dual now, with that i5 you should comfortably have enough grunt for 8.

You'll run out of RAM first.

You should be fine running those 4 VMs

thanks guys.

I was going to upgrade to the e3-1240 which has 8 threads.

I guess i can save my money.

I have 16gb at the moment. I guess i can just buy another 16gb to run more vms.

CPU is generally never the bottleneck, it's memory.

Definitely save your money, and only invest in memory if you need to - The performance graphs in ESXi are excellent so it should be immediately what constraints there are.

Agree here 100%. Memory is key for ESXi - and also if you can afford it, fast disks (SSD) for your storage.
