Intel X4500HD Chip on G45 Board

I checked the graphics processing charts but could not find any 'onboard graphics chip performance results' on any of them.

I completely understand if OBD graphics aren't included because they just don't fly for gaming.

But, where would the new Intel X4500HD graphics chip on the G45 motherboard come in at relative to nVidia's card lineup?

More specs on the X4500HD chip can be found at:

I'm no expert on the exact particulars but do plan to run Microsoft's SDK examples on this new G45 machine versus my nVidia 8600GTS machine just to see what happens. The hardware versus software rendering is easily noticeable.

Thanks for any input. Joe
