Doubt regarding AMD graphic card in inspiron 15R

[kula]

Hi all,
I have a doubt here .
Suppose i am choosing AMD Radeon HD 7670 in my laptop configuration will the Intel Graphics 4000 (default) be removed or not present ??
Another doubt is whether will the Intel Wireless Display Technology work if i have a i5 (3rd gen) with AMD radeon graphic card ? Because i see in the intel site that the basic requirement for the Intel WiDi is Intel Graphics 4000 .. Hence my doubt .
Thanks in advance .

^ Don't worry. When you have both the 7670 and hd 4000, the laptop will use the hd 7670 for more graphics intensive applications(gaming etc) and hd 4000 for tasks which do not require heavy graphical prowess(surfing the web,ms office etc).

Can't comment on the wireless display part though.

@Jripper : Thanks Jripper...
Can someone through light on whether WiDi will be possible with AMD Radeon 7670 also on board ??
