I guess it's mainly because it's looking at a smaller range of games for the multi gpu tests, on tomshardware and some other site that I now can't find again the total sum of fps though a bunch of games at 1280x1024 with AA etc maxed was higher than the 4850s. Granted they are extremely evenly matched and even slightly better going into the 1680x1050 and above mark. Like I said before it all goes down to your personal preferances, on what other parts you run and what monitor you run. Just mentioned the 1280x1024 results as thats what I thought the majority of people use.
