What's the point on getting nVidia GTX 400 series?

the point is that A: you have one expensive pc (to brag about) B: you have one fast pc (to brag about) and C: you can brag about it. you will also not need to worry about replacing the card anytime soon either. if your running linux you could have some AMAZING compiz effects going on that thing and you might be able to hit its limit, but i doubt it.
