Just the 1920x1080 version non3d, doubt it matters. The 2 part numbers I'm about to list you need to get for the m18xr2 because the antenna is too short for the m17.

5XHG5 - WiHD Card

KVR0Y - Antenna

Also you will need a receiver keep that in mind.

I have tried R3 parts which are Sibeam Gen2 and even the R4 parts - Sibeam Gen3 which came out when the R4 was first released but quickly pulled. I have tried every combination I can think of with no luck whatsoever. I messaged an Alienware rep (a reputable one) who informed me that with their testing, they have never gotten WiHD to work on an R4 with an nvidia card.

So Alienware Rep was wrong. I've had my Alienware m17xR4 working with the WiHD technology from the m18xR2. I have the nvidia 680m as well. I've been using it for almost 2 years.

does anyone have an issue with the r4 idling at around 70-80c?

I keep having an issue with my 680m under clocking itself lol.

^ yeah I'm with him. Looking at it, the 7970m is a very comparable card. I'm more with NVIDIA to take use of the CUDA cores.
