"650Ti Boost is working on very high frequencies and temps thus leaving no space for OCing, whereas 7850 can be boosted quite hard. At the end we look at Watt/FPS, where these cards should be equal."(This is from one of your own links)
And so is this "i don't think that its better than my card since my card is clocked at 1050 mhz core clock so that makes my card better by 14% (according to GD)and the reference 7850 is clocked at 860mhz and still only a tad slower than 650B.so if a 7850 is clocked at 980,it is already better than 650B.i just saw that 650B has more tdp than my card so i think that 7850 is still good
"
Your links refer to the reference 7850 while mine refer to the actual cards themselves after they leave the manufacture (i.e. Gigabyte, MSI, HIS, EVGA, XFX, I think you get the idea...)
Clearly my benchmarks outweigh yours! Enjoy your 7850, iLakerz! Don't let the Nvidia fanboys keep you down!
