The huge bandwidth is needed when writing or reading textures (that canot fit into local videomemory) to RAM.
Current Intel platform cannot provide such bandwidth, HT 3.0 can.
Bandwidth or not, system memory is way too slow for real-time rendering. Maybe it would matter if system memory was GDDR3. DDR2 is too slow to begin with, then you have to account for the hop from system memory to CPU northbridge, via HyperTransport to the motherboard northbridge, then via PCI-E to the GPU.. You can't spin that to be relevant, because it simply isn't in any way.

Games are rarely CPU bound, so I don't see how this is new to anyone. If you play at high resolutions CPU hardly matters.
