The earlier Nehalem (?) i3, i5 Core processors have embedded graphics, Intel HD, which IS BETTER then the GMA series all told, but it can't match wits with discrete graphics, it CAN RUN GTA games, however, they will have issues, I mean GTA 4 of course, the install requirement is having Shader Model 3.0 support.
The Atheros I'm familiar with from a mid-2000 Toshiba laptop, I used it well enough, though it was G- rated, rather then N
A new Wireless standard, Ab I think, is proposed to succeed the n band WiFi, and it's going to operate above 2.4 and 5Ghz ranges where the most traffic is, IIRC
Depending on the motherboard, some discrete graphic option MAY exist, as in my case I made clear, Acer's 4710 has a revision mobo supporting MXM cards, but this is not promoted generally, you have to dig about for the info!!
