Interesting points, but several of them are flawed IMHO.
#1- its EASY, just hit the benchmark button. (I don't even know how to benchmark most games, too many variables)
That's definitely true, but there are also many other options available when it comes to tweaking, and that's a good thing too. Anyway, the ease is a bonus for beginners, but I'm guessing most of us here are able to perform a simple benchmark in the games we play.
#2- It looks better than other benchmarks. (Well except now there's UT2003)
That's true to some degree too, but it depends on your taste. However, benchmarks aren't meant to be good looking, they're meant to just produce performance figures. The stuff you see on screen is simply a side effect of the measurement process, and having it look good is simply a bonus.
#3- There's one number at the end.
Which is good for beginners, but not so good for more experienced people. What does that number mean? How is it obtained? Also, actually there's a breakdown of individual scores in 3DMark2001SE which you forgot to mention.
#4- Bigger number means better performance
Not neccessarily. It simply means better performance for that particular benchmark. Even within the benchmark there are many different "game scenarios", some video cards perform better at one than another.
#5- When you hear 20000+ 3dmarks, it peaks your interest.
Well I don't know about you or the rest of the people here, but it doesn't peak my interest.
#6- Nobody else has come out with a good looking, easy benchmark
True, but again the ease and good lookingness is more for beginners.
#7- People need to show off some kind of number- like a 0-60 time for cars.
Yup, and I'm not opposing that a 3DMark2001SE score is ONE of the numbers to show, but many people are using it as the ONLY number worth showing, which is what I'm put off by.
#8- There's no such thing as real-life performance because games aren't real life.
OK, you're taking it literally now, real-life/real-world isn't meant to be taken literally, it simply means performance in the games you play, apps you run. Now, if all you play and run all day is 3DMark2001SE, then that's the benchmark you gotta use since its a direct reflection of the performance you're gonna get, but I pray that most people have more life than to do that all day long.
