can Alienware M17x R2 support Nvidia video card ?
I have a alienware M15x with Gtx 260m and M17x R2 with Hd5870m single card , Ati 5870m is a powerful video card , however , it does not have Physics processor as Gtx 260m ., I want to play a game with physics on my M17x R2 , so I think it s better to install the Gtx 260m on it . I pull Gtx 260m from M15x ,and replace the 5870m on m17xR2 with Gtx 260m . I download the gtx260m driver for m15x .However , the driver can not be installed . whatever way I tried install it in , it always appears to be " standard Vga graphics adapter " in the device manager . I then update the Bios from A05 to A06 for 17x R2 ,but still the same problem .I have tried formatting the disk and reintalling the windows 7 ., not recognize Nvidia graphic card . I have tried searching the nvidia driver folder and open the INF file to select the correct model to install . .Having no choice , I tried removing the harddrive on m17x R2 and just replace the harddrive on m15x ( since M15x and m17x R2 have almost the same chips on the motherbord ,both are intel pm55). To my surprise , Nvidia Gtx260m is recognized on my M15x with the harddrive from M17x R2 !. How come ? can it say that M17x R2 does not support Nvidia graphic card anymore ?
