Since your love for gaming is not going to stop just by playing DOOM , it will continue.... and the future is bright and so PCI - E will be always with you in the coming future of games.... this is just the beginning.... There are games that are under development which is being targeted at this PCI -E cards only, which means you can play this future games only with a PCI-E based card. So go get one for yourself !
