ATi were rather happy to see that error report analyses of all the ones sent to Microsoft revealed that over 25% of Windows Vista crashes were caused by nVidia cards. And their new HD4870X2 is an absolute beast - in a perfect entirely AMD/ATi-tailored setup, this is how far it whoops the GTX 280's backside according to ATi:

The GPU race is just getting insane. Each companyis making entire lines of their
own, never mind besting the competitor, obsolete virtually every month. How can they keep this up? How can it be economical to produce a card when they'll just make a better one which fits the exact same bracket two months later and have to retool the production line? It boggles the mind.
Really, there isn't much hassle in retooling the production line.
Most production is being done at TSMC chip fabric company. They can adapt their wafer technology to nearly any chip you want. The only thing is the process technology (how big the transistors are in nanometers). But TSMC, being a company which produces chips mainly for others, is making these investments themselves. After all, they have to keep the deals and be able to produce chips for other companies. That problem also isn't with the developers.
The first real 'planned perceived obsolence' trick was made by nVidia with their own 8800GT. It made the 8800GTS, the previous ones with 640 and 320 MB of memory, really obsolete. It even put a strain on the 8800GTX sales, which was much more expensive, much hotter (90 nm) and only offered about 20% more performance.
ATi did the same with their 2900 Line, but hey, was that a problem? Those cards couldn't compete anyway.
Obsoletion of the own lines are nowhere near as much of a problem as competitors offering better results. nVidia's market share rapidly decreases because ATi has better stuff, and with that also the market value. That is a real problem. Compared to that, it is no big deal to have increasing developing costs, and thus products which make your own cards obsolete. As long as you are on the best of the sales, it will stay positive for the company.
Concluding, it's more important to keep marketshare than to keep your own lines intact.
