Wow this is a old thread, Not sure why it stopped but I'm sure it was a lot to keep updating. Pretty much was a good reference to see which cards out performed another, Back then there was a much closer battle between ATI/AMD vrs Nvidia so when someone had a budget and found a few cards in that budget they could see which one performed better. But now there are a lot more on the net to see which cards are better for a particular price point. Right now Nvidia is ahead especially on the lower power consumption vrs power of the GPU. Don't take that wrong about AMD because they too have some good cards but they take turns leading the other and IMHO Nvidia is in the lead and there drivers are just as good in the lead.
Damage? as in price? that will depend on what you want to spend vs what you expect in performance. Check out Newegg and you can see the price range. There are many threads on here talking about GPU performance if you don't know much between the various cards.
I can always add it to a Google Docs spreadsheet and make it available for updating that way. Though I wouldn't be the best person to update it, and I'm not sure who has the time that's knowledgeable enough to actually do so .
