Tesla M10 32GB with ESXi setup question

Hello,

I have purchased a Dell730XD with two 14 core CPUs with a lot of RAM and SSD space. My desire is to create a group of gaming servers. I must use one Windows host per server and am using ESXi. I was planning on buying a Tesla M10 w/ 32GB next week. My worry is doing the setup wrong and wasting a lot of money.

To start with, the setup document states that you need to install "Horizon".

The cost of the cheapest Horizon version is $3100. Is this NEEDED to get virtualization? That is a LOT of money. What are my options outside of using Horizon? Is what I am trying to do even possible without Horizon?

I appreciate your time reading my post, thank you.

Cheers,
Pete
