Same to me, flanker. This my second ati after some years of nvidia 4200, 6800, 8600, 285. I had some experience with a 4890 and the other name I don't know
So normally I stick with nvidia due to the fact, that I do not care about money, when I am interested in a new card. Just looking at 285 and 4890, there were many games running better with the 4890, but my brother couldn't use it very good for his games.
After reviewing and really taking care about it and talking to many people, doing benchmarks with all different parts all day long, I decided to buy a 7970. The initial benchs of the 680 were hardly discussed for hours and it was simply a horror show, that happebed also at some independant magazines or websites. Some really good sites really did a bad job, mostly reviewed some weeks ago. Now it is all good but this hype was crazy and unfair. Both cards are now equal for my games with a little advantage for my hd7970. I am still glad to have it and I am still convinced, that it is the card of the current generation up to date. I wondered about the good results of the 680 and was impressed, except the point, that they seem to sell a product, which was not fully ready. More features like computing were surely on their plan, but they simply cancel and nevertheless sell it as fully featured (same with bios probs and newest pci-e support not activated, although stated on the package).
Nevertheless there is nothing to argue about. No need of laying his computer engineering balls on the table
