why do you need a USB card: My system doesn't have a USB 3.0, but my Steam library is on an External Drive, so 3.0 would we faster.
and a sound card? The sound card on my Mother Board is notoriously bad.
4gbs of VRAM isn't a requirement I guess, but a goal. I have Humble Bundle Monthly, where I donate to a different charity every month and I get free Steam codes. I now have over 300 different Steam games, so I just want to make sure they all run well.
I do not have a current GPU. This is my only PC. I am saving up to build a VR system, but that's a year away, and then this will be my spare.
