So what's the deal with the "HD" GMA chipsets? Are they really any different from normal GMA chipsets? Apparently Flash 10.1 GPU acceleration supports the GMA4500MHD and other 'HD' Intel integrated GPUs. Surely it doesn't offer the same performance boost as ION or any real card, right? But what can it do? Anybody here have one? I ask this because on my notebook quest, I have found that the ASUS UL20 and UL30 are excellent laptops, besides the fact that they have GMA4500MHD GPUs. If the GMA4500MHD is actually worth something and may help out HD video streaming, then the UL30 may be what I end up getting for college.
