I have 3 machines with Intel graphics that I run compositing on with compiz and they run fine. Like I said so long as you disable the blur plugin in compiz it's pretty solid. Actually, recently I installed KDE4 on a VM and ran KDE through XDMCP with all the compositing effects turned on and it ran smoothly as well. The "X was eating CPU" seems to indicate that it's not the GPU that's doing the 3D rendering but the CPU. Now if you got slow performance yet your CPU was sitting there doing nothing then I'd suspect the Intel Graphics.

If I try to run composite rendering, X eats my CPU time to the point that I can't even use the system for practical purposes. I have a 945GM Intel video card. I had tried compiz-fusion through kde3 last year, but the performance was much to jittery and slow, so I removed it. I tried to upgrade to kde4 this week, but again X was eating CPU time and making the whole machine run hot and slow. I can't be 100% sure it was the video card and composite rendering, but I believe it was the problem. So I switched to xfce and now I'm happy. So, if you want to run 3D graphics and composite rendering, maybe not intel? ~daid

The software support for Intel graphics itself is pretty good. They have in-tree DRI drivers and X drivers and support for GEM and XRANDR 1.3. IIRC Keith Packard works both on X11 development and the Intel drivers so you get a lot of support software-wise. As some have reported Intel Graphics cards don't perform as well as other competitors in 3D graphics. It's fine though for people like me who aren't gamers and need powerful graphics hardware. I use GNOME/Compiz and things work pretty exceptional (except for the Blur plugin in Compiz; there's no hardware rendering support; you'll want to disable that).
