Again, thank you all for participating.
Although opinions are diverse, it seems most are in favour of the 3700x.
In that case I would need a good motherboard. Don't want to go too low, nor too high. I read that the "ASUS TUF Gaming X570-Plus" is a good one (Wi-Fi, DisplayPort). Only two PCIe, but I really need one for the GPU.
Wanted to move away from ASUS, but I see MSI boards being criticized and ASUS seems more favourable. Or is there a more suitable option? I'd like to keep it slightly above 200 Euro.
Does the CPU come with thermal paste or I need to buy it separately?
As for RAM. What is better, 3200Mhz CL14 or 3600Mhz CL16. I'd like to keep it within the range of 200 Euro if possible (preferably 32GB).
Edit: MSI MEG X570 Unify seems far from release and I don't think it will be close to 200 Euro in price. Not sure I'd even need it for a 3700x.
