modtech wasn't making any kind of personal attack prow, you're reading into that wrong I think, he was just trying to point out to falco and road why he feel's the benchmark program is worthless like you stated (don't think the post was even directed at you).
And to be honest, he was basically summing up exactly what you're saying any way. The benchmark doesn't really reflect the type of performance you get while playing games, it mainly just gives you a decent comparison between systems. He was basically saying the same thing that you have concluded, only adding that because of those reasons it is a bit childish the way people strive to max out their score for bragging rights, when all that really matters is the performance you get while gaming.
