Can I use 2 different gpus (GTX 1070 and a GTX 750ti) in the SAME computer and operate it like 2 different computers? (I have dual monitors)

I have 2 different gpus and im wondering if I can have 2 different desktops. I only have 1 computer with 2 monitors

You won't be able to have two different desktops, as after all the only thing you have two of are the graphics cards. The computer itself is the same. So short answer is no.

Long answer is yes, if your motherboard has good IOMMU groupings, and you install Linux and the necessary VM tools to passthrough the second GPU and a set of IO to a VM, and then sit down with two sets of peripherals to run essentially 2 PCs out of the same box. Not sure what the point is but it can be fun to mess around with.

I was just about to edit my post and say something like this, but decided that considering the OP's question, this probably wouldn't be something that he will consider / is considering. Then I say what you said and I agree. Long answer is that it is possible, but probably the hassle to make it all work is not something that is worth it.

Exactly lol. I've messed with it before for fun, but unless there's a reason you need a VM with its own GPU, monitor and I/O, it's a lot of hassle for no real benefit.

I want to run 2 of the same game on the same pc. I have a asus prime z390-a. Do you think it will handle it?

You'd have to do some google digging to see if anyone else has one and has already recorded the IOMMU grouping, otherwise you need to get Linux (I just used Ubuntu) up and running, and track down the commands you need to run to see the IOMMU grouping. Then if you can split out the onboard I/O you're good, otherwise you may need a USB card for a mouse/keyboard for the guest. Also important note, AFAIK you do have to have Linux as the host since the tools are built for that, so if the game you're trying to run does not run on Linux, you're boned anyways. 

Also some games will ban you for playing in a VM. Depends on how their anti-cheat works, but since you're using the host RAM as the RAM for your VM, many anti-cheats see that as an outside application messing with what's in memory (this is how most cheat programs load in their files), and auto-bans you. 

I think there's some sandboxing software you can use to run multiple instances of games in Windows, but again depending on how the game's anti-cheat works that could result in a ban.

maybe a server grade dual cpu socket system can help but doesn't seem possible on his current, there's nothing like that for consumer grade, atleast for now
