So apparently there's this mod out which allows you to play Goldeneye with improved graphics using the Half-Life 2 engine. While I haven't played it yet I have sampled the 30 or so tracks on the game and they are fantastic. They stay true to the original tunes but sound much better. See for yourself:

Amazing, saw some previews on youtube. I would definitely buy a new PC and HL2, gotta move up to that Source engine meng. This mod is insane !!

I don't actually own HL2 but the music is much appreciated :)
