To Neil:
Direct Interface to video extensions - DIVE
Video bus bandwidth : 7282.561 Megabytes/second
Is it really that much faster than an accelerated ATI card?
This VBB value is typical for latest Intel built-in video with a proper set of caching mode for LFB.
We need somebody with such processor and ATI card to know what is faster (I am curios too).
And it will be necessary to test this issue on real applications not only Sysbench. I am using SNAP with ATI x850 and when I switch my comp to Panorama for tests, I recognize dramatic decreasing of scrolling speed (for example, any help file in NewView). Probably, on latest Intel built-in video, such decrease will not happen.

I'm curious, what are you guys setting your VIRTUALADDRESSLIMIT to?
Pre Arca SNAP has a bad habit - it is mapping ALL memory available on a video card into address space (if I am not wrong, even twice).
It looks absolutely senseless - just a waste of address space.
Fortunately, there is a way to "fix" this. "gaoption vidmem 8" reduces size of mem to be mapped by SNAP to 8M (it is sufficient for 1280x1024x16M)
I always use VIRTUALADDRESSLIMIT = 3072 (/CACHE:262144 for JFS.IFS)
