this is my plan for my current build for a gaming pc to play fps and sports and racing games, etc.:
Intel - Core i7-8700K 3.7 GHz
GIGABYTE Z370 AORUS Gaming 5
NVIDIA - GeForce RTX 2070 Founders Edition
CORSAIR - VENGEANCE RGB Series 16GB 3.0GHz DDR4
CORSAIR - Hydro Series 120mm Liquid Cooling System
Samsung 970 EVO 1TB - NVMe PCIe M.2 2280 SSD
CORSAIR RMx Series, RM1000x, 1000 Watt, Fully Modular
CUK Stratos Full ATX Tower Gaming Desktop Case with 7 RGB Halo Fans, LED Lighting + Tempered Glass Windows
Alienware - AW2518H 25" LED FHD GSync Monitor
and keyboard, mouse, mousepad, etc, around $220 (without tax)

Plz remember that my budget is $3000 (including tax)
is my build good, and should I change any components? Is it all compatible? I have already reached my budget.
Please answer with any other stuff needed like speakers, etc.
