Man!!
Most of people posting on this board have no clue about HSR in first place (I'm one of them). There are probably only a few who know and could explain the HSR algorithm and how's implemented, I mean really explain it in detail, not just say "well, this calc is performed then this check, blah, blah." E.G. Could you write the software for the HSR algorithm?
To rest of us it's all speculation and bullcrap. Nobody here (aside from the experts), knows who's got what and who's HSR will be better. Reading a few white papers on z-buffering (see, I don't even know what z-buffering is?!) and other crap doesn't make anyone an expert on graphics. Unless your a game/multimedia/grahpics software developer, or work in the card industry, you probably don't know squat, alright?!
It's like two Americans who only speak English arguing over Japanese pronunciation. They both have heard Japanese spoken before, but don't know crap about the langauge. They should both shut up and talk about something they know.
NEWS FLASH: No graphics card company will own up and say, "Ya, some our cards features really suck." They all want to make as much money as possible; they don't care about you, me, or any other consumer.
We should all just wait the for real proof of performance: non-beta drivers that deliver the goods
I wish people would either stick to what they actually know for a fact, or just quote the experts in the perspective field of discussion. But some posters on these kind of topics, it seems, blow a lot smoke, argue with equally clueless people about abstract facts of which they themselves have no clue, and kiss the butts of people who agree with their clueless position. Heck, I've been guilty of the doing this too.
I don't want to berate anyone who posted above, but honestly fellas...stick to what you know.
