Advice on €1500 build

Almost zero difference day-to-day between the 7600 and 7600x. Not going to impact sound recording or gaming significantly. The 7900GRE is certainly a better option over the 7800XT for gaming but I'd argue the 7800XT is better value and certainly very capable. 32GB of RAM is good. Any decent NVMe drive is as good as the next for gaming. For handling large sound files you might see a benefit but I'd still suspect any half decent SSD will do the job. Might be able to time quicker boot times but you'd struggle to notice without a stopwatch.

What sound recording software are you looking at? This should guide your CPU choice. If it likes more cores/threads then a 7700x and the 7800XT strikes me as the best combo for your use.

Also, word on the street is AMD is about to drop it's price of the 7x00 GPUs to clear them for Q1 2025 of the next generation. Just food for thought

As long as you are aware AMD could be dropping pricies significantly very soon. But they won't be giving them away either. Also, AMD doing game bundles with certain retailers as well. Worth a look especially for Space Marine 2 alone.

If all you are doing is tinkering then your build is fine. Just to check, what about case, keyboard, monitor and mouse?

And, you'll be happy with either the 7800XT or the 7900 GRE. it's a 10% difference in performance and both will play 1440p with high settings on pretty much all AAA titles out there right now. At the very least you are going to get time out of both until well into the next console generation.

I'd also be careful to assume any part will be still capable for 10 years. Hardware from the mid 2010s got away with murder for the last decade for a multitude of reasons. A perfect storm if you will. 5-7 years or the console life cycles are a good rule of thumb.

Yes, only free delivery from Amazon UK. Can still work out cheaper though
