All looks good buddy! All compatible with one another, and yeah I’d say that’ll easily last you 7 years! The only recommendation I’d give is - do you need this PC today? Nvidia just announced the 4070 super today with 20% more cores and 16gb of vram. It may outperform the 7800xt for the same price, but, if it does, your 7800xt may get a 50-100 dollar reduction. So give it a couple of weeks and I feel you’ll either:

• Get a better GPU for the same price
• Get the same GPU you already want for less
