Gone a little over budget but the rational is the following:
There is no point in buying a 7800X3D/7900X3D and 4080/4070 and running a B650 board, you need a 670 or 670E. They have more lanes than the 650 and the VRMS on the 670 are better.
It's a PCIe 5.0 compatible board so you should use PCIe 5.0 components if you can (It will stand to the longevity of your machine ) - explains the 200 for the storage.
Again, there is no point in running a power hungry GPU and CPU without a Platinum class Power Supply.

If you wanted you could drop back to a 7800X3D but that CPU 40% less performant than the 7900X3D (And you'll only save 90)

Note: PC Part picker doesn't include jacob.de which is great component seller.
Note: For an extra few hundred you could got for a 7950X3D which is an absolute beast

Edit (originally did US but switch to .DE website)

You could go for the 650 Board and a 7800X3D, I'd stick with the platinum power supply that would get you down to around €1800

The elephant in the room is the graphics card. They are just gone so expensive now.

There are options:
1: You could buy second hand - risk
2: Go for a previous generation like a 3080 -
3: Go for a OC 4070

You're down to around €1500 now.

If you're looking for benches on games for the 4070 there's a good review here:

At 4k the 4070 will run Counter Strike at 190 fps

The PC Parts picker is just an example. Do you research on the Hardware vendor website

Avoid the Samsung SSD's for now, the 980 had a massive F**k Up there a few weeks ago and the price of them is coming down. PCIe 5.0 isn't a must but defo something to strive for.

Also, on your monitor, how old is it? (Make/Model/Hz?) if it supports Freesync too you can use AMD GPU's

If you don't care about raytracing then AMD's GPU's could be another option. A 7900XT will outperform a 4070 in non raytracing applications and its only an extra €120

Note G-Sync and Free Sync only matter when you're below 100fps if I'm honest.

No it does not

I'd do as @K.O.Kiki says and try and get a 4070 Super if you can.

Those mini cases are one of the new cool things. (Case market is quite busy right now)

The mini cases can be slightly noisey, cause the get a bit hot depending on what components you use, hence higher fan speed.

I like them, but don't own one… I've the exact opposite infact.

Lian Li have a lot of nice cases, but again if you look at case reviews on gamers nexus they do quite an in dept job.

There are basically 2 types:
Mini-ITX
Micro-ATX

Could be the otherway around actually

Anyway, they're very small The ITX one is tiny, be careful if you don't go with an AIO CPU cooler as an air cooler might not fit in the case. Same applies to the height of the RAM.

One thing we both forgot to add to the list of things to buy is case fans… you'll need a few.

If you're gonna go AIO for the CPU then I'd recommended the ARCTIC Liquid Freezer III (It seems to be the best one out there at the moment). Agreed that Corsair stuff is so incredibly expensive

I'm currently using a Lian Li Galahad AIO and it's be great, very quiet. BUT, I've had to warranty replace a few of the Fans as the bearing went in them… (Not great)

My concern would be if you're using a Lian Li A3-mATX, you're gonna struggle to fit in the GPU and a Tower cooler. (I don't know for sure though)

Consider Low Profile Ram such as Crucial Pro 32GB Kit.

My Opinion on this has been to always buy the best as it will last longest, but don't put yourself in debt like

I made the Corsair mistake

G.Skill is the ram to buy

@awec Is that price for the CPU with a stock cooler included? I don't see one listed

AFAIK "big brand" is more applicable to USA where warranty claims are handled by the OEM; whereas here they'll be handled by the reseller thanks to EU regulations.

And even then, the biggest OEMs like Asus have been exposed as being absolutely terrible.

@Beta Ray Bill Most GPUs use cold plates with heat pipes; very few use vapour chambers - and even the ones that do it doesn't make a huge difference.

The INNO3D RTX 4070 Ti Super does great in all tests I've read.
69C core, 83C hotspot, 70C VRAM @ 270W is damn good.
