Paste the output of lspci -vvnn. Look for "VGA compatible controller." Here is mine:
01:00.0 VGA compatible controller : nVidia Corporation GT218 [GeForce 210] [10de:0a65] (rev a2) (prog-if 00 [VGA controller])
Subsystem: eVga.com. Corp. Device [3842:1213]
Those are the relevant parts. The red sections identify the chip and card as being nvidia driver compatible.
