Even though you have CI+QE, dont let that fool you. You probably still don't have 100% video acceleration, but you might have, if you are lucky. Just compare the following scenario procedure with Pages (iwork06) in your computer.
My specs: p4 2.6 (sse2)
ATI 9600XT 128 (CI+QE+Q2E+Beam sync disabled)
512mb ram.
Open a new document with Pages. Type randomly at a higher rate (doesnt matter what you type). Then click "Show Layout" on the menu. Now repeat the typing. If you notice a slowdown, then you don't have full video acceleration. If you don't notice any difference at all, your system or GFX card is better supported.
(This "test" is for exploring the performance for us OSx86 users in various applications to get a broader picture of compatibility in the system).
Please post your specs also.
