Gaming pc build up

[pettersuk]

After a 5 year break (due job change) I decided to get/build a gaming pc BUT, because of lack of expertise I’ll need a hand from you guys.
• At the moment I’m looking around 800£ to spend.
• Not an issue about second hand parts (monitor)
• Need suggestions if will be better to buy it in parts or just tryin’ to get a good price from a shop.

Due to time frame I’m out of knowledge (video, processor) so what would you recommend me for mainly COD warzone/ Pubg/ CsGO on a medium/high spec?

I know it’s a long shot, but I’m absolutely confused at the moment as I’ll need some time and research to catch up with everything.
Thank you

thank you all for reply and suggestions.
In the end I ended up buying this second as it was really a good price:

Case corsair 9011049
Power corsair cx 750
Cooler hyper 212 led
I5-7600k
Geforce gtx 1060 5gb
16gb ddr4 3000
Asus h170 pro gaming atx
X2 - 250 ssd

now; what you would recommend guys to upgrade first on it? Video? Cpu?
Should I go for a gtx 1660 super 6gb or higher?

le: on partpicker I end up with this message...
Warning!Some Intel H170 chipset motherboards may need a BIOS update prior to using Kaby Lake-S CPUs. Upgrading the BIOS may require a different CPU that is supported by older BIOS revisions.

What is about it exactly?

I would want a much bigger upgrade than a 1660 Super to be worthwhile, more like a 3060 Ti, but the 1060 6GB should be fine for your needs for now.

The only CPU upgrade (unless you use a modded bios) is outrageously expensive so I wouldn't bother.

would not cause any issues adding a 3060 or 2060/70 on it?

cpu upgrade you mean if I wanna go in the future to i7?

btw: at the moment I’m running warzone at 100/120 fps on low/medium settings - very happy for a 400£ set-up
