The Nvidia 8800U samples we saw look just like Theo said with OEM parts going out at 612/1080 clock. The cooler is designed for quieter not cooler operation.
The core OCs decently with about 10% higher achievable, with memory not getting anywhere near that.
On a highly OCed Kentsfield running at about 3.5GHz - all numbers slightly blurred to protect the guilty - 2G of DDR2 running at 1200MHz on a 680i board, the score I can talk about is 22,000+ in 3DMark05.
In the end, it looks like the card is memory bound, not core bound. The Ultra scores better than a GTX with a massive core OC, so it looks like the main upgrade here is the memory. Call me overly skeptical, but is this really worth that much of a premium? µ
