Nice Cornerbck, my Sentia entered Phase 9 as well today. I'm hoping it gets packed and picked up by FedEx this afternoon from AW. I've been told FedEx doesn't deliver on weekends, so I'd have to wait until Monday if it doesn't get picked up today or early tomorrow.
As for replacing the Intel card in a laptop, it is
possible with the correct chipset.http://www.intel.com/products/chipsets/gma950/index.htm
That's Intel's page all about the Intel Extreme Graphics 950 (the graphics card in the Sentia). It clearly states that the card can be upgraded, but there is a catch. If you have the Intel 945G Express chipset you can upgrade the graphics, but this is a desktop chipset.
The Sentia m3450 uses the Mobile Intel 945GM Express chipset. Intel's specs lists the Mobile 945GM as having a a PCI Express x16 graphics port. However, if you follow their link to the Graphics Media Accelerator built into the card it says upgrading of the graphics card with the PCI Express x16 port is only available in the 945G desktop version of the chipset.
Some of Intel's "Performance Chipsets" for laptops do support graphics card upgrades, but since every Sentia is equipped with a 945GM it does not seem possible. But, that doesn't automatically mean it's impossible in "99.9% of laptops"... all depends on the chipset and how the laptop is built.
The Sentia still meets the reccommended requirements for games like Counterstrike.
