Question Is is okay to use parts of my upgrade already?

Sep 3, 2020
So I recently decided to upgrade my gaming rig at the end of the year. I am looking to upgrade my GTX 1080 to a RTX 3080, my Msi H270 Gaming M3 Motherboard with a Asus Rog Strix z490-e Gaming, my 16gb corsair lpx ram with 32gb (4x8) G.Skill trident Z RGB, my Cryorig R1 Ultimate cooler with a Kraken z63 and my i7 7700 with a i9 10900k (perhaps I will reconsider this when AMD or Intel announces a new CPU till the end of the year). Now, every compontent kinda needs one another to work (couldn't use the new CPU with my current motherboard) besides the Cooler and the Memory. I would buy those two now, use them in my current rig (memory support only 2400) and then transfer them to the new rig when the time comes. What do yall say? good idea/bad idea and what do you generally think of my upgrade plans. Thanks in advance.
