Like it or not, the truth is that both 69xx and 79xx DOES suffer huge performance hit when MSAA applied on the Frostbite2 game engine. The issue is real, and has nothing to do with what Nvidia has to offer on the other side of the fence.
Prices for the new cards are too expensive. Getting a 7950 now comparing to the GTX580 which is available since over a year ago would be a bit like...how should I put it...yes... had AMD launched Phenom II X4 955/965 without waving the big "budget build flag" and priced it as high as Q9550/Q9650 which available since a year earlier and becoming EOL by the time Phenom II X4 launch, would people have gone for the Phenom II X4 instead of going for i5 750/i7 920?
Faster than the GTX580 the 7950 might be, but the margin is so small and it still put them as same level/rank cards. The thing that people are not impressed about the 7950 is that it is only offering pretty much similar performance to something that priced the same and was available and sold since over a year ago. Nvidia and AMD card owners alike agree on this, so STOP calling ANYONE that has anything negative in slightest said about the new AMD cards Nvidia fanboys, as you are just making yourself out to be a crazed AMD fanboy.
