I always skip over any non real world test. I see no point in a number that means nothing about how my game will play and how fast apps will load.
I only see a use for these benchmarks for OC'ers and nothing more.
(non of these # are real just a example)
This is how i see these benchmarks.
Say a 680get's 10,000 and a 7970 get's 9,000 I would go ahead and say the 7970 is 10% slower.
So by basing on this you then go out and buy a 680 you go to play a game you run that games benchmark compare to a 7970 and the numbers have changed to 680 90 fps and 7970 100 I would than be angry and be confused as it was 10% faster in 3Dmark, but in this game it was 10% slower!
Now this example probably was wrong, but I'm trying to say is that you can't base your purchase off of 1 benchmark.
I also only pay attention in reviews to the games that " I " play on, because I don't care if a 7970 was to get 120fps and a 680 10000 fps in a game that I don't play. That's why I like W1zz's reviews because they do have lots of Game's and many of the ones I do play.
