Upgrading my gaming PC, need help/suggestions (not my cup of tea)

When you say "price range 2000-3000", is that invested amount, or actual upgrade amount? Also what currency is this in?

Anyways, likely good choice on the 1080 Ti, though you may want to look at AMD's upcoming Vega too. Personally I'd stick with Nvidia unless AMD can somehow manage much better pricing at near or equal performance. The software problems with AMD drivers alone are not worth it IMO, and I'm currently on an AMD btw.

The CPU end of things are looking good so far for AMD with their new Ryzen though. There's no user or even test site GAME benchmarks yet, but if HardOCP's CPU Mark benches are accurate, the X1700 8 core is easily beating the 6800k 6 core at tasking, and priced lower (price already confirmed at Fry's).

The real problem is, it's all too soon yet to really know how the 1080 Ti will compare to Vega, or the Ryzen CPUs to Intel, when it comes to gaming. However it IS now known that a X1700 will cost only $50 more at launch than Fry's current price on a 7700k, which is pretty incredible considering it has twice as many cores and a MUCH higher CPU Mark score (which may or may not translate to gaming performance, depending on games).

So on the CPU end, considering the new products out now, it really depends how much you use your PC for tasking, editing, or anything non gaming related, but it also will depend on how many more devs continue to support 6 and 8 core threading in their games. I think that time is coming soon, if not already upon us. So if you're the type that keeps your systems for some time, you may want to consider that.

It also depends a lot whether AMD's Ryzen CPUs will drop pricing on Intel's units. That is very likely, and it may even affect their quad core CPU pricing.

As far as the RAM, you can't use DDR4 on an 1150 MB. I'd also say you don't need more than 16GB RAM, unless you're deep into 3D modeling or something.

So with DDR4, you'd be looking at a new MB, and that of course would mean a new CPU as well. It looks like your 4770 is not an unlocked k model, so you may be stuck at 3.4GHz. I'm pretty sure your H model MB is not OCable either anyway. Thus you'd likely bottleneck a 1080 Ti or Vega with the 4770. How much so would depend on how CPU dependent the game is.

The 7700k is a pretty decent CPU for now, but who knows how much longer 4 cores will be adequate for all games. It runs hot though (Ryzens are very low wattage btw, so they should run fairly cool). At any rate, you're going to need to wait a bit longer to find the info you're looking for, or even obtain some of the parts you want.
