Is the bottleneck from a 7900x cpu with a RTX 5090 worth worrying about?

I have a 5090 on the way soon from a preorder and I currently use a 7900x CPU. Will the bottleneck from the 7900x be a big issue? I plan to upgrade the cpu at some point maybe next year unless the bottleneck is a big deal then I might get a 9800x3d. I would rather buy a new case and other parts instead at the moment. I can oc the cpu as it’s watercooled?
