I think alot of people dont understand the mindset of gamers. If thats their primary usage, its usually greater than almost any other pc usage being done , simply because its hands on, in the now, so to speak, experience. Using winrar, or encoding etc, its set it and for get it, and isnt the same experience.
What's not to understand? It's totally logical and practical. A gamer doesn't spend nearly as much time RAR'ing or encoding as staring at the raw FPS of some game. They don't even spend that much on the GPU - after all, have to spend time at work and away from games to buy expensive GPUs when turning down the eye candy usually works.
Take a look at the Steam monthly survey -

Notice 90% of gamers there use just 1 or 2 cores, over 50% have 2 GB or more RAM, and over two-thirds are using XP 32-bit? That looks like a business installation with preference for price/performance/compatibility. That semblance stops at the GPUs, but extravagance isn't popular there, either - half of 1% have Radeon 2900s, and GTX 260 and 280 each account for 1-2%. The 4800s (think 4850) are making inroads at 6.5%, but the largest installed base is still the 8800 series, at 27% (I bet mostly 8800GT's).
More 4870s were sold than almost any other card for serious gamers since its inception.
You mean 4850. 4850~8800gt > 4870 > other GPUs (excluding lower-end discrete cards). The 4870 performs noticeably better but falls behind in price/performance due to the substantial premium. And as we just saw, gamers apparently chase price/gaming performance, not gaming performance or eye candy at all cost.
There's no comprehensive sales tracking, but individual retailers often report such results. E.g., http://www.tgdaily.com/content/view/39938/118/
I realize this is the CPU section, and every day we talk about i7's, Phenom II's, original Phenoms, even GTX200s vs 4870x2's. But volume for these products is relatively very miniscule not just for ordinary Joe but for gamers as well. We're
enthusiasts; not gamers. The desktop volume is in Wolfdales and 4850/8800-level GPUs. It's the enthusiast in us that goes for Q6600s/9500s and 4870s, or i7's and SLI GTX200s. Half the i7 owners aren't even serious about gaming. Someone's 920 in this thread is paired with a 4670; my 965 recycles an x800...
