hi can any one offer me some advise, i have a nvidia riva tnt2 model 64/ model 64 pro graphics card, only most new games won't even install as i don't meet requirements. i have asked a few people but they all tell me to buy a new computer, i don't want a new computer as mine is a cracking little machine and i don't mind spending money on a new graphics card. what should i look for? whats the difference between pci and a pci express? is it true you can piggyback graphics cards? if so would that work for me? and which one would work for me? i know its a lot of questions but i am quite curious and don't know anything about them
