Welcome to the forums, newcomer!

1| You might want to look into a B850 chipsetted board, steering clear of ASRock boards and looking at a board with a beefy VRM design.

2| That would depend on your games installation size and how many games you have in your library.

3| I'd set all fans to intake and leave the rear empty to allow for positive air pressure and see how your temps are.

4| This site and the majority of it's userbase are located in USA, since you're located in Iceland, you should mention your preferred site for purchase so we're able to see what you have access to. Brand and product availability can and will vary with regards to region. Deepcool is banned in USA, mind you...while you guys might not have favorable pricing for other parts.

I would look into the RX 9070 XT or the RTX 5070 Ti if they're priced the same as your GPU listed above.

Thank you for the review!! I’ll look into the b850s. What kind do you recommend? This is the site that I use for purchasing all my parts (https://vaktin.is/index.php?action=prices&method=display&cid=11). This is for the cpu cooler(https://tolvutek.is/Tolvur-og-skjair/Ihlutir/Kaelingar/Arctic-Liquid-Freezer-III-PRO-360mm-AIO-vatnskaeling-AMD---Intel,-svort/2_40566.action).
