Yes, but can't you just try it to see if it works better? Then
you could ask your ISP to change the MAC address in their
dhcpd.conf to match the new card.

No, that is not actually the MAC address. It's a "DHCP client
ISC dhcpd uses that in preference to the MAC address, actually,
so it might work if you put a new card in and then set the
dhcp-client-identifier to be the same as the MAC address of the
old card, with a "1" in front of it. I don't know if it will
actuallu work, though.

Set the hardware address of this interface, if the
device driver supports this operation. The keyword
must be followed by the name of the hardware class
and the printable ASCII equivalent of the hardware
address. Hardware classes currently supported
include ether (Ethernet), ax25 (AMPR AX.25), ARCnet
and netrom (AMPR NET/ROM).
i.e. you can set the MAC address of the card using ifconfig.
