Dunno, I am still playing games from err 'last gens' as theres no gens on PC. Best thing is when you play old game with new computer you will get even better graphics than before. For example I just found one great old rpg called wizardry 8. It can be sometimes blocky, but with extra resolution and with bigg & better effects it actually looks quite nice sometimes.
(Btw, that isn't prerendered. Game came out just after playstation 2 came on the market. You can set resolution up to 1280x1024(32) nowadays and it looks good. :) )
