I now have done enough research and am confident about the VR machine I'm looking to build. It's going to roughly cost me almost $6,000. The reason behind all of this is because I also want to be a developer and render high quality 3-D images. On top of all this development, I also want a machine that can reasonable sustain high performance with all of those beautiful games on the side.
I guess if I spoil myself too much and end up wasting time on it more than developing, then I would be wasting my money for a system I could have settled for much cheaper. Yet, since I have some professional experience these days as a programmer. I think it settles it then that I really like it and should get into this creative activity for myself.
