Interesting. Ive just recommended the dr150 to a mate of mine as he loved my dr50's so much.... might just tell him to get dr50s
Well, I can't say either way which would be better, but I have seen some people comment that the DR50's were preferred for gaming. That might be their preference though, rather than being just a case of the DR50's being better for gaming full stop. Plenty will likely prefer the DR150's, so until one can compare, it would impossible to say.
I shall endeavour to get the DR50's from a friend of mine to compare. I know I have said that before, but he isn't using his PC much of late, so it gives me an opportunity to nab them and give them a go. It's Christmas though, and there is plenty to do, so that's assuming I even remember!
