Few words

CPU
Put in i7-8700K that you can OC if you like. CPU has 6 cores and 12 threads which can handle everything you throw at it.

CPU cooler
I'm not a fan of AIO water coolers since you won't get any additional cooling performance over air coolers since both are still cooled by air. But what you get with AIO is higher price and more noise. So, put in Be Quiet! Dark Rock Pro 3 which is one of the best CPU air coolers and it's few degrees short of Noctua NH-D15 (king of air coolers). Oh, it also has nice black looks where NH-D15 brown/beige fan colors are mostly hated,

MoBo
Put in MSI Z370 Gaming M5 MoBo which has plenty of features for all gaming needs. MoBo also supports CPU and RAM OC,

RAM
Put in 16GB DDR4 3000 Mhz RAM that you can OC from 2133 Mhz to 3000 Mhz. RAM itself has black heatsinks, so it matches the CPU cooler and MoBo theme. It's also a normal profile RAM and won't be in the way of Dark Rock Pro 3.
Note: do install the RAM before installing CPU cooler, it's easier this way.

SSD
While i could put in 2.5" SATA SSD to save some money, but with the budget of yours, i went with M.2 NVMe SSD which is 10x faster than 2.5" SATA SSD. That, and it also mounts directly to your MoBo where you don't need to mess around with SATA data and power cables.
In my Skylake build (full specs with pics in my sig), i have the very same SSD in use as an OS drive.

HDD
Didn't put one in since you already have one.

GPU
The one you requested.

Case
Didn't put one in since you already have that one too.
Note: you'll need 165mm of CPU clearance for Dark Rock Pro 3.

PSU
But did put in PSU since the one you have is crap quality. There are no reviews of it on the internet and the unit itself also doesn't have 80+ certification to give a little hope of it being better than crap quality. Instead, i put in the best 650W PSU money can buy at current date.

With Seasonic PRIME 80+ Titanium series, you'll get the highest efficiency (94%), tightest voltage regulation (0.5%), longest hold-up time (30ms), lowest ripple noise (20mV) and longest warranty (12 years) there is. Fully modular cables and toggle-able Premium Hybrid fan control too.

My Skylake build is also powered by PRIME 650 80+ Titanium PSU.
Oh, all fully-modular Seasonic PSUs are also compatible with CableMod SE-series custom sleeved power cables.
To match my Skylake's black & red theme and Haswell's black & blue theme, i have replaced the stock black power cables with CableMod SE-series custom sleeved power cables,
