Should I bother with current PC games given my PC's limits?

Update, in case anyone gives a shit:

So I decided to bite the bullet and just buy Bioshock. I do have to run it on almost the lowest setting, but it doesn't look as bad as I thought it would. It looks like a kick-ass last-gen game instead of a kick-ass current-gen game, which is alright with me. I know I'm missing a lot of the experience it has to offer, but it's better than simply missing out on this amazing game.
