Dude, can I humbly suggest that you slow down a bit and let us actually try to resolve each issue one-by-one?
Rushing about is just causing more expense and more frustration!
Bluetooth: this could have been addressed earlier, if you had let us know that you needed it.
not only does the motherboard not support wifi, it also doesn't support bluetooth
USB wifi sticks (at least, the cheaper ones) often
only support wifi, unless otherwise specified in their description.
The PCIE cards that I've suggested to you in this thread, ALL support bluetooth, subject to having a free USB2 header on the motherboard (* see my earlier post below).
To be clear: if you decide to go this route, this is something that would
need to be checked before purchase.
I have zero motherboards in my house with wifi/bluetooth, yet all of the PCs have wifi/bluetooth, thanks to a PCI-E card. This is a resolvable problem and doesn't need the PC sent back.
USB is the easiest, as mentioned ^^
PCIE is often superior in my experience, but you'd have to check there's enough space between a free PCIE slot and the graphics card. They also often need a free USB 2 header on the motherboard
if bluetooth is required.
I can't see any problems with PCIE lane sharing from a brief look at the specs.
I'd suggest cards that are Intel based, since I don't have much experience with the alternatives. I have a couple of
these and they work fine.
and can't play World of Warcraft which was pretty much the main objective of building this new PC.
You made another thread for this issue right? How's that going?
There are lots of users of AMD cards playing WoW (I have even done so myself), so I expect this should be something we can fix.
I did call your attention to this as a potential issue in your build thread:
Can you share the link to the article itself please.
Just to clarify, main usage is MMOs and WoW specifically?
The reason I included the 7800X3D is because MMOs and especially WoW tend to like them, but if that applies to WoW classic specifically, I don't know.
The 5070, I agree that it is not the best card. £500+ for 12GB is argh, but I tend to spec nvidia for WoW because of reading a bunch of reddit posts awhile back about crashes. I think that was only with one render mode enabled and it was resolved after some time, but since I don't play WoW and this game is not included in most popular reviewers benchmarks, I'm not aware of how they perform now.
