Cyclone V vs Kintex 7 (Resources and Performance)

I did some further checking and found the Kintex 7 to outperform the Arria V at -3 speed grade. I'm really considering whether the TimeQuest timing analyzer is accurate or if I'm misusing it. Can anyone comment if the figures shown in the 0*C/85*C timing models right after a compilation is the fmax to be looking at? If the Kintex 7 can outperform an Arria V, I'm beginning to think picking up the Kintex 7 is a no brainer, but I'm worried I might be doing this comparison the wrong way. I'll see if I can grab a Cyclone V to do some actual testing, but I don't actually have a Kintex 7 to physically compare.
