I've known people who have called themselves "IT Technicians" who though an 8500GT was top of the range, and the 512MB of RAM it had meant it was "really fast". They also thought 1024x768 was high res.
Reminds me of old friend of mine which opened a PC shop few years ago, he used to think that 3850 was a top end card ( at the times where we all had 4870s and 4890s and GTX 270/280 was already released ) because it plays all games great - forgetting the fact that he played on 17" monitor with 1024x768 res and without stuff maxed out but obviously he didn't know that it makes any difference.
I'm wondering if the business is still up and running...
Funny thing is that I still see people go to ( a week ago even ) ****** (ah forgot 'competitor' - well known store with mainly tools and electric stuff rather than any pc hardware ) and pay 150quid for 9500GT. I don't think anyone would be hurt in any way if he's got 6870 for 200.
