Intel’s cheapest iteration of P35 and G33 is starting to ship this week. The chipsets are being shipped to a motherboard manufactures that place the order by very late June, probably to make the Q2 financial numbers a bit prettier.
If you wanted to be sure that you are the first at the list you should have placed orders in middle of July.
The first chipsets should be in hands of motherboard manufactures and first golden samples motherboard should be finished next week or bit later.
This will definitely bring a lot of cheap integrated graphic boards on the market or the ones without integrated graphics with really acceptable price.
