yes everest can work, but if it dont, take the card out, and look at every word, letter, and symbol that looks like it might be a serial or model number. any strings of letters/numbers you see, google them, and chances are you might find it. (this is how i found out that i had a 3dfx voodoo3 2000, and a 3com 10/100 NIC)
another good program that works is syspec, and sometimes powerstrip can identify your display adapter too.
