I have an alienware 18 with dual gtx 880m's in sli and am interested in upgrading to gtx 980m's. I've had trouble finding any info, forum threads, or videos of people making this upgrade. There's no shortage of people upgrading from earlier gpu's to the 880s or upgrading from 970s to 980s, but very little on earlier gpu's to 980s which has prompted me to ask why? I've seen plenty of threads of people asking if it's possible and the answer is always yes, but then it seems no one has actually done it and told the collective interwebs about it? Any help here would be appreciated.
