I don't have much faith in polls. I think hardcore gamers have good cards and people who buy new systems have decent setups for gaming. Maybe not ideal, but better than nothing. Your average joe that plays games is not going to invest money in a video card on any kind of regular basis. They might not care or they may be uneducated and not even realize what a 3D card even is. They may not be able to afford it, etc.

Anyway, real gamers will upgrade, but I don't think your average user will do so every time Company A releases the latest greatest; thus that's why you should not shoot for the moon when you create something and why I have no faith in polls with a tiny 1000 hits (there are millions upon millions of PCs of all kinds out there....1000 hits doesn't represent anything). There are a LOT of old systems out there with owners that are not replacing their cards and probably never will until they buy a new system, and that doesn't happen too often either.

A lot of us on here live in a bubble. We upgrade because we are gamers and/or developers. We think because it's normal for us to do it that EVERYONE is doing it or at least most. I simply don't think that is the case.
