I3-530 review
http://www.bit-tech.net/hardware/cpus/2010/01/04/intel-core-i5-661-core-i3-530-cpu-review/5
Just built a low-end I3-503. NOT a good bench mark, but the win 7 graphic scores were both in the 5s. (Neither AMD/Intel chips with inergraded graphics are very good for anything above low end game requirements)
Other than low end games a real graphic card should be used and would score about the same for both amd/Intel. For CPU intensive tasks the I3-530 would be a better choice.
If Not into Overclocking, the Charts included in the link provide stock CPU speeds.

This link compares the IGP for the I3 to a GT-220 - Not sure how that compares to the IGP of a 785g
Build for my wife: NOTE Low end games, for her any game over $10 is a rip off
I3-530 (will OC), H55M-2UD2H (No sli/xfire needed), Corsair 400 W PSU (can easily run a 5770 GPU), 4 gigs of ram CL7 1.35 V (Cheaper available).
$365 Hard to beat.
I added a 3rd party HSF for $23.
What I didn't need to buy at this time. (I'll probably buy her a new case (HEC 63RABB and latter on the 5670 GPU)
If need new operating system (Recommend win 7) that adds $105.
If needed (as I already had):
New case - $40->$60
HDD ($50 -> $75)
DVD writer Approx $25
GPU - 5670/5750 approx $120
