Any reason to wait buying PC components until after new NVIDIA card?

[lovemesomespeed]

I'm planning on building a sim racing PC soon, and since I only have a few months (hopefully) to wait until the 3000 series NVIDIA GPUs are released, I'm not bothering buying a GPU until then.

Is there any reason I should hold off on buying all the other components? Is there any chance I would buy a montherboard or something else now and then find out it isn't compatible with the new NVIDIA card?

Generally consumer GPUs are compatible with almost every motherboard supporting the slot.
I've only ever seen two occasions where in that did not happen.
In both, a GPU was shipped and physically installed but no working driver from the respective ATI/AMD board partner was released.
That was back about 12 years ago.
As to buying components now...there is never a right time.
Choose what you want and dive in.
They're many good CPUs on the market at present.
You'll need to look around and do some 'home-work' for the best prices.
Covid-19 seems to have caught everybody at home buying anything they can get their hands on.
As a result, components are up in price due to demand.
