hey guys i own a alienware m17x r4 with a 7970m i was under the belief that i could crossfire my laptop with another 7970m! but have since been informed that the r4 did not.. i thought that the r4 with the nividia gpus could not bee crossfired as it didnt come with a extra gpu slot.. i was looking forward to upgrading my laptop. i am annoyed if this is the case cause i planned on ssd sswap as welL!
