u should really wait for pascal polaris... coming in BD in august i guess... will be released in june
btw just so we are in the same page... as u said u were not playing games in pc for a while... u dont need 3000$ pc for ultra gaming dx12/dx11 60fps 1080p unless the game is arma 3 or ark survival... for most games 1500$ pc is enough for 60fps 1080p ultra/near ultra
even if u want to 4k gaming now... you will still face hard time spending 3000$ for 4k pc wisely... so i still dont recommend above 2000$ pc.
here is some price in BD... i am not suggesting brands
5820k 32k
+x99 chipset motherboard ~25k
ddr4 ram 3200 bus 32gb ~18k or 16gb 10.5k
ssd 500gb samsung 950 m2 18k... or intel 480g 14k
hdd 4tb ~11k
casing.... nzxt 7-9k, antec 6k... or maybe more expensive nzxt... or maybe 700$ tt level 10

? as you have lot of money apparently... but i dont know how u can buy level 10 700$ in BD
good powersupply 650w ~8k or 750W ~9.5k
cooler- 9k wataa coola
980Ti 65k
188k without monitors/speaker/gaming mouse/pad/kb
maybe u should buy 6770k instead of 5820k.... it will cost less and z170 motherboards are cheaper...
