You are clearly a Nvidia fanboi. Personally, I have no problem with that, but your bias does not allow you to see clearly. Anyone who is objective however, is very much aware that RV770 series was clearly the superior solution this last generation, Nvidia even acknowledged it at their very own GPU conference two months ago.
If you need anymore "proof" than Nvidia admitting their product was inferior, than you can peruse any reputable tech site, their benchmarks will substantiate my "claims", which are not so much claims, rather common knowledge.
As for your statement that the OP can decide whatever GPU to get, why didn't you follow your own advice when you initially responded in post #2?
