Would this work with a crossover cable, so you can avoid the (ridiculous) expense of a 10G switch if you wanted to connect only two PCs together?

The TP-Link TL-SX105 5-port 10Ggps is available now in late 2021 at a not quite so ridiculous expense of $320.

Will i get 10g speed over pcie 2.0?

PCIe1 is 250MB/sec per lane, PCIe2 is 500MB/sec per lane, PCIe3 is 800MB/sec per lane. So an x4 PCIe2 slot has..... 2Gb/sec transfer capability. 10gbe is 1.2Gb/sec transfer speeds, which falls nicely within a PCIe x4 slot. If you're computer can drive data that quickly is another question. A single consumer SATA SSD can only do 400-500MB/sec , and SATA3 can only do 600MB maximum, which is under the speed of the 10gbe. So unless you have a RAID setup with SSDs, you cannot exceed the ethernet connection. Or, a nice NVMe m.2 drive can do 3600MB/sec easily, which will hurt the 10gbe connection.

can this work as a 10gigabit connection in between 2 systems if both have one of these like from a file server to a workstation pc

Yes. That's exactly how I'm using a pair of them, between a Linux file server and desktop. I manually configured IP addresses and routes.

Is this card low profile? does it come with the low profile bracket?

The card comes with a standard size bracket but a low profile bracket is in the box.

Problème de conflit au redémarrage

La carte utilise son propre drivers à l'inverse du modèle Tx401 qui utilise directement le driver du fabriquant. JE ne sais pas si c'est cela qui est en cause mais une fois la carte installé dans le pc avec le driver d'ASUS, au prochain arrêt/Démarrage, il y a un conflit avec le CPU empêchant le pc de démarrer. JE n'ai pas rencontré le problème avec la carte TX401

Sehr gute Netzwerkkarte

Die Netzwerkkarte kann man sehr schnell in ein bestehenden PC oder Server einbauen. Sie wird nach der Treiber Installation problemlos erkannt. Es ist jederzeit ein Einkauf wert.
