at its most basic anything that fulfills the Red Hat hardware compat list, there will be others but as always chance it wont do its thing

Check the compatibility list.

Read comprehensively.

Make sure it fits your motherboard and the correct bus speed etc.

Don't skimp on the cost. Latest ain't always greatest.

Beware some cards may have internal limits - I had a HP dual or quad port one that looked 1Gb ports but there was something odd they'd cut corners with & effectively throttled the card. Took me a while to figure.

Check interwebs & foros for "<my new card> issues" etc.

Ah yes this gem.

"So essentially a lot of NIC cards cannot handle Gigabit PPPoE - the frames come in and all hit a single queue and the card can't handle that.
Lots of people get round it by offloading processing to the CPU which can handle multiple queues."

It is to do with the internal queuing and memory. Worth a detailed read.

My upgrade from 10Mb ADSL to 1Gb fibre found out quite a bit of kit!!

There are some tests you can run to check this but I retired the recalcitrant equipment so don't have notes on how to test the cards I'm afraid. I think ethtool iperf are your friends here.
