Hi,

I'd like upgrade video card on Alienware 17 R1. Actually running on gtx 770m and wondering about gtx 970m/980m but not sure if it's compatible. I have already 240W power adapter secured. I have found this topic but I'm not sure if I have the same model, so rather to asking...

Can anyone help ?
