Am I wrong? New Ram prices have me considering upgrading to 5900xt (AM4) and scrapping AM5 build upgrade

I wasn't going to waste any money on am4 build, figured I could use all that money toward am5 bundle build, but now with RAM prices skyrocketing, I think buying a 5900xt or 5800xt on sale is viable option for me.

using 5600x and 3080 gpu, does suprising well, but notice some cpu struggles, especially alt-tabbing. figure a 5900xt will help and I have seen them go on sale for around 230

Is this bad idea? If i can get a 5900xt for ~230 usd, I am thinking it is "good enough"
