A:AnswerYes. If you look on steam, this pc’s GPU is more powerful than the minimum. It should be able to run VR games just fine. Don’t know why this other person said it couldn’t.
A:AnswerWith most pc's like this one, they give you crappy Ram, PSU's, and motherboards from random Chinese companies that no one has ever heard of. Just get an Nzxt prebuilt from https://www.letsbld.com/starter-series. Trust me, this will be a better buy for you!
A:AnswerIf you wanted to add more ram to the system, you would need to remove the existing sticks. Combining different ram is not a good idea. They would be from different manufacturers, speeds, and gb. But, I would not recommend buying this desktop pc. Most prebuilts like this one are targeted at buyers who are not experienced with pc's.
