OK, you have a valid point. AMD/ATI have every right to withdraw support from old hardware. Just as MS has every right to withdraw support from old OSs.
HOWEVER, if the MS upgrade advisor tells me that my hardware will run , if I install ATI's new catalyst software, and ATI's support site tells me that my hardware will run in Win8 with their Win8 Catalyst software, why should I not believe them?
I know that ATI swore on a stack that they would not issue drivers for HD3000 series beyond Win7. But they did. 12.6 was supposed to work in Win 8. I did not see any caveats about outdated MOBO's.
To summarize, if you don't wish to provide support/drivers for an old card, say so, and stick to it. If you DO provide drivers, then make sure they work. Basic contract law.
For myself, I took your not so polite hint and looked about for alternatives. I discovered a MOBO/CPU/Memory combo which satisfies my limited needs (no, I'm not a gamer, so maybe I shouldn't be on this forum in the first place). This ridiculosly cheap bundle eliminates the need for an add on video card. Microsoft, to their credit, will allow me to use my bargain 32 bit license with the 64 bit version of Win 8. We shall see how that works.
For me, all's well that ends well.
At the risk of repeating myelf, if you don't wish to support old hardware, say so in full caps. If you care to continue support, then make sure the drivers work!
