Not completely, no. I had (and still have) a really decent '07 card (non-integrated 6600GT on a desktop) that always was largely sufficient for everything I wanted -- desktop, development, multimedia, even most 3D Linux games would run smoothly. It worked like a charm for everything when I ran non-compositing WM (I used GNOME2/Metacity at that time), and it was able to perform accelerated video decoding through VDPAU, which was very nice as my CPU of that time couldn't really cope with full-HD decoding -- and my current one is just barely able to keep up. But when using GNOME3/Mutter, my graphic card quickly runs out of its 256M of VRAM and could not perform hardware decoding anymore whenever I have like a dozen windows open (which is basically always, mail, browser, IM, IDE, a few terminal windows, audio player, ... it grows quickly), rendering it impossible for me to e.g. watch HD videos without closing other apps. This sounds a little crazy, but it's a decent '07 card, not even some integrated chip of that time. And I believe my setup to still be completely relevant today, even if more modern similar cards probably ships with 2-6 times as much VRAM. I don't plan to invest in a new graphic card for my *desktop* to run. So even though compositing WMs looked like a nice idea originally, I'm really not convinced anymore (or at least the X11/mutter impl is wrong, I didn't try anything else seriously). The only real benefit is visual effects, for which I don't care. They are nice and all, but they don't help me using my computer any more efficiently or more comfortably. I wouldn't care if it didn't get in my way, but as explained above, it does as a side effect. Sorry if this somewhat strikes as a rant, but please, don't assume everyone updates their hardware every 3 years.
