Maybe you haven't heard. IGP will be on ALL future chipsets from Nvidia and AMD/ATI.
You won't have a choice about getting IGP even on high end boards.
This scenario won't happen in the near future. But of course I'd like to see some proof/sources for this claim. I know AMD is bringing Fusion processors in the near future, which have graphics integrated into CPU. What would be the point in Fusion, if there's already going to be an IGP in every chipset?
Au contraire, the very next refresh on both sides of the fence are going that way. It'll only take a few months to debut, a few more months to fill the channel, and a few months after that for prior generation products to empty out of the channel. In the grand scheme of life it is going to happen shortly.
If you think months are a long period of time you might say that isn't near future. I'd say it's roadmapped in and inevitable.
Wait a second you think Fusion is a near future project?
APU stands for Accelerated Processing Unit, and the first one is Swift. You might have heard of it earlier as Fusion, and it is set to come out in the latter half of 2009. What it is, is a 'stars' core with the new northbridge from Griffin, a GPU and PCIe on board. Basically, it is a system on a chip, but unlike other SoCs, it is aimed at the high end, not the low.
The point of Fusion/APU is low latency. Once you have Crossfire/SLI concepts fully developed there is no where near the drawback of an on CPU video controller like there was back in the early Celeron days.
Timna was the codename of a proposed Processor Family by Intel. The Project was announced in 1990 and was designed in Haifa, Isreal. It was supposed to be the first Processor with an Integrated GPU and Memory controller which was designed to work with RDRAM. The price of RDRAM did not drop as expected by Intel. So, It was decided to use a Bridge chip - Memory Translator Hub(MTH) and link Timna with SDRAM. Later, a serious Defect was discovered in the Design of the MTH and so had to be recalled. The MTH was rebuilt again but problems still remained. Timna was canceled on 29 September 2000.
I expect to see IGP across the board before fusion makes it to the masses.
I don't bookmark these sorts of things as I read them but here are two links.

In the past enthusiast boards had chipsets that had the integrated GPU disabled just to keep it out of the way. Now the drivers and board level control will be there to use an IGP in a constructive manner no matter how many add in GPUs you have.
Use it for power saving, SLI/Crossfire, Physics, distributed processing. In some way or another most any user will find a use for it even if they don't know it is there.
