Question Thunderbolt 4 expansion card

[adamghering]

ok here is another upgrade question

Im currently looking to build a machine around the ASUS ProArt x670E creator WIFI which has a lot to offer but there is a chance that it may not play well with the AM% 7000 series so im hearing

if I go with the gigabyte board (x670E xtreme) it doesnt have native thunderbolt/usb4 headers
so I would be sacrificing that

There are Pci-E cards that you can isntall but:....Question
most of these cards are only Pci-E 3/4 which maxes out, according to the internet at 32gbps
which would seem to truncate the 40gbps of the thunderbolt port...

or am I missing something?

Thunderbolt also has to carry DisplayPort signals, so the extra bandwidth is likely to make sure that you're not losing PCIe bandwidth due to resource contention.

Can you pass on the add-on cards you're looking at? Asus Thunderbolt card's have a compatibility list and also need a header on the motherboard to work in tandem with the motherboard.

IMHO, just make sure you've got the latest BIOS version and you should be fine, compatibility wise.
