but I would expect that your primary clients would be reviewers, graphics card manufacturers, and anyone else who needs detailed statistics on a video card.
I would consider selling primarily to professionals who need to benchmark stuff for their magazines and websites, like Tom's Hardware. And I would charge a price to match that clientelle. Like Sysmark is $400.
That would be something like <1000 sales and no one here would have any job left because we would have been out of business ages ago... 3DMark is not a pretty & free demo, it's much more and there are enough peeps who do buy it as a valuable tool.
In the past we gave away too much for free and that wasn't a good thing for us, obviously. Of course peeps now say that 3DMark sucks because you have buy it to get all the features... tough luck, we have to eat :)
And since any new 3DMark requires very good (the best) cpu+gpu when released, any casual "hey let's check out some cool demo" audience is quite small. And only one version? I can count four + one upgrade... pricing being from US$9.95 to US$250.00 :)
