Well since you guys headed that way. The forum overlords have granted nVidia the right to populate the forums with their focus group. Here is one of their views on it. There are some interesting things to be read.
"Janooo does have a point that because it appears to him to be a certain way (and it appears that way to others as well) that someone (Anand and I) need to make a decision about the situation.
There are multiple layers here by the way. If there are viral marketers on the board, then they are more dangerous than anyone who has a known association with a company. But members need to be smart about how much credit they give to people on a certain topic.
On factual info about NVIDIA products, these guys are a great source.
For information on the value of features or the meaning of performance results, not so much. Or not at all really. And definitely not for information on competing products or how well they stack up to NVIDIA products. Every one here needs to take everything these guys say wrt these topics and largely throw it out the window. And you have the information right their in their sig to know that you need to do that.
I'm not saying that NVIDIA Focus Group members themselves are even the problem. The problem is deeper than that. It's call indoctrination.
As keys says, he knows 1000x more about NVIDIA hardware than AMD hardware. He is also exposed to NVIDIA's PR team and product managers. These guys are really really good at what they do.
It is much more effective to win converts and send them into the world then to hire salesmen.
And frankly NVIDIA's technology is impressive. It's easy to show people how awesome something is when it is awesome. Especially when they aren't as immersed in AMD hardware goodness and don't have as hands on an experience with the under-the-hood behind-the-scenes stuff from the competition. Not spending the time with AMD hardware and people that they do with NVIDIA hardware and people is a detriment to Focus Group members ability to accurately assess the market.
This should not be surprising to anyone.
People who see and play with demos and future games based on PhysX without being shown comparative examples of the software run on CPU and competing GPU solutions will color those people's opinion of the value of PhysX at this stage in the game. AnandTech's assessment is that you can't judge the real value of a feature until games ship using it. The assessment of others may be that the potential is awesome for PhysX on NVIDIA hardware ... but what if it's just as awesome on multicore CPUs (in practice) or on other GPUs? Sure, theoretically PhysX offers more, but we don't have anything "game play physics" related that is compelling at this point.
CUDA is great. We've had the AMD implementation of folding@home for a freaking long time though ... and AMD had CTM before NVIDIA had PTX ... and they've got CAL which is basically the same deal. We really need a unified standardized compute language, as I don't see language extensions created by anything less than an industry standards group actually satisfying the needs of everyone. I hope OpenCL ends up being what we need but only time will tell.
Seeing the performance numbers, the price, the fact that AMD can support c/c++ high level GPGPU computing as well through Brook+ or other tools, the fact that PhysX (or even Havok) support could be implemented through CAL / CTM (or a high level language if they're lazy) on AMD hardware, and a complete lack of compelling software using these features on NVIDIA's hardware (it's all demos, add-ons, lame effects and stuff that's supposed to come out in the future) absolutely does mean that someone with a well rounded perspective would conclude that GTX 260 is not worth it's price compared to the Radeon HD 4870.
NVIDIA Focus Group Members cannot have this well rounded perspective unless they work very very hard to overcome the natural barriers to neutrality put in front of them.
And it's not even really their "fault" -- it is their perspective that is tainted. "
