Question Help choosing the right Gpu for this build

[Raiden170]

Hello im buying a used pc from a friend and doesn't have the GPU which one do you recommend for this build? im thinking 1080 or 1080ti but i don't think a 1080ti is worth for this build or maybe even an 2080 ?
I gonna use this PC mostly for gaming.

Power supply: Seasonic Focus Plus Gold 650W
RAM: Corsair Vengeance LPX 2x8GB DDR4-3000
CPU: Intel Core i7-8700
Cooling: Arctic freezer
Case: Corsair Carbide 400c
Motherboard: MSI H370 Gaming Pro Carbon
SSD: Crucial MX500
HDD: Seagate Barracuda 2TB

Also where do you usually buy this stuff ? i used to buy in a italian site but it closed so now im guessing amazon?

Well, that must be a philosophical question as rest of the system could use any GPU you can throw at it. It's just a question of what games and at which level you normally play. M;y answer would be, buy best one you can afford or are willing to pay for because it will last longer and be actual longer. Any money saved now you'll pay double in next couple - 3 years.

What resolution and Hz is your monitor?

Get a 2080. It has 0 bottleneck and perfoms the best with i7 8700

if you got the funds......go with the 2080. I got a 2600x partnered with a 2060 and it runs games (BF5, SOTTR, GRWL, etc) on ultra setting without issues. good luck
