So I'm not much of a gamer (My main game is TF2, and I don't really play any of those AAA games), and have decided that I'll go with a GTX 950 for the PC build that I'm planning on buying. However, I'm a HUGE fan of virtual reality, and plan on trying to get my hands on it as soon as it is a bit more budget-friendly, as well as when I have a PC to run it.
Now the question is, can I in the future, add another GTX 950 to my previous one and have the power to run VR, or will I have to buy a new graphics card and replace my 950 with it?
