As I see it strictly from the Best Buy website, the G74SX-BBK9 is the better deal over the G74SX-BBK11.
It has 2x500 GB 7200 RPM drives vs. one larger, but slower 1x1TB 5400 RPM.
It has a Built-in 1.0MP webcam
and microphone. The BBK11 does not advertise a microphone.
It has Built-in high-speed wireless LAN (802.11b/g/n) and 4G WiMAX (provided you purchast a WiMAX Service Contract). The BBK11 only advertises WiMAX as the wireless internet connection method
and specifies NO Built-in high-speed wireless LAN (802.11b/g/n.Both are priced at $1249.99. For my money, I want the 2 faster HDD's (more reducduncy too), microphone, and wireless b/g/n networking.
Here is what I culled directly from the website:
