I have a build with an Intel i9 10850K, Z490 Motherboard (Build). I built my PC in November 2020.
I was hoping to get my hands on an RTX 3080 in a relatively short time but at least where I live (Italy) they don't exist at a decent price. I found out last week that from AMD's official website the video cards are being restocked consistently. The first time I tried I almost managed to purchase a 6900 XT. I think I only failed because it was my first time, and I didn't have Paypal access and didn't see the box to accept the terms of service when confirming the order.
I think I will be able to purchase it when they come back in stock.
Should I be concerned about anything regarding the compatibility of my build with an AMD card? (Like PCI-E 3.0 etc...)

nope, all good

The tests people have run for PCIe 3.0 x16 vs 4.0 x16 had results that fell within the margin of error, so no worries there.
I'm running an RX 6900 XT in a custom loop with my OC'd 9700K @ 5.1Ghz (no avx offset) and 3200C14 memory at 4133 C16. My system runs like a dream :3

You should be good. I ran my 6800XT on a B450/3700X (pcie gen 3) for 5 months until a couple of weeks ago when I upgraded to B550/5800X. I'm not sure how much of a difference gen 3 and 4 make but I do notice improved fps in some games and my graphical score on Time Spy went from 19110 to 20358.
That's an idea for you. When you get it run a Time Spy test and compare your score to other people's but you should be all set imo.

Watch your PSU, I just upgraded from a 2080 Super to a 6900xt and my 850 watt PSU is cutting power in games after a few minutes due to overzealous protection circuits. May not be an issue for all systems and PSU combos but it's something to watch out for. I'm working with the PSU maker to see about a solution.
ID: gyh3a5qWhat CPU do you have? An 850w PSU should be way more than enough for a 6900xt + most CPUs...
For reference I'm using 3900x + RTX 3080 (which iirc pulls more power than 6900xt) and I'm not sure if I even pull 600w when gaming
ID: gyhfsutI'm on a 5800x and even using the calculator I should only actually use just over 600w. From looking at the forums its a known issue with this PSU for some reason when it spikes usage in game momentarily. EVGA seems to have been working with people to get it fixed when they have problems but I just ran into it with the upgrade.
My build with the upgrades:
ID: gyh682mI read something online and 750W should be fine. At least I hope so, I don't want to spend money on a new PSU.
ID: gyhz3wgJust don't OC your CPU.
10850K can pull as much as 250-300W when OC.

i'm using 6900xt vs z490 and i5 10400. may look funny but totally fine, absolutely no problem. even i have resizable Bar enabled. and it's completely stable. Here are my benchmark results.
ID: gyh3j7vI've got exactly same rig, got my GPU this morning. Do I need to enable resizable bar? Or is it activated by default? How to test it then?

your pc is good mang.

All good, enjoy!

I have a similar build with a 10850k and a 6900 XT, it's working fine.

You are fine, if you play at 1440p or 1080p the 6900XT is faster than a 3090, sometimes by a lot. I'm also from Italy and got an RX 6800 last week from AMD direct. Gone from an i7 8700 + RTX 3070 system to R5 5600X + RX 6800 and in some games I have 25% more FPS (closer to a 3080 than to a 3070)
You will just miss Smart Acces Memory (for anyone wondering, no , resizable BAR is not SAM, it's based on the same tech but it's not the same) and the absurd power efficency of the 5600X.

I have a 6900xt with a 8700k on a z370
Seems fine

AMD R9 3900X please.

Incrocio le dita... 6 mesi sono stato senza GPU con la integrata dell'Intel, mi va bene tutto.
