What should I upgrade next?

[Lulabeast]

I came here when I wanted to build my computer and now I'm ready to start shopping for some upgrades. I'd like to eventually get into VR, or at least get it VR ready. I'm not sure where my bottleneck is, but I'd like to upgrade the parts that will have the greatest impact on performance first.

-Thank you so much for any advice you can give me. This community has always been really great about helping people like me and I am very grateful.

Here is a summary of what I have installed:

I'd put it all into GPU (as long as whatever you choose is adequately powered by your PSU).

I have a fairly similar setup, but using a GTX 670 instead of your 760 which are arguable the same thing performance wise. I also use a 3570k instead of the 4590S which again will be fairly similar. I know that if I do a VR test it's my video card that causes the slow down and is the thing I'm looking at replacing evantually.

I'm not sure what your budget is, but I've been looking toward the new GTX 1070 if I can scrounge around the cash to sink in to my machine.

If that really is your monitor, personally I would look in to replacing that if you end up replacing the video card. It seems like a waste to have all that GPU horsepower running at a lower resolution like that. I think you'd get a much better experience out of your machine overall with a nice monitor to stare at.
