I own an xps 8900 and a upgraded psu Corsair 650 W and I want to update to a gtx 1060 , I should be ok with my psu but what length or dimensions of the 1060 is the max ? I was thinking about getting the EVGA 1060 FTW which is 10.5" long, or do I need to get a shorter version of the 1060 ?
MSI GTX 970 4G Gaming is 10.91" x 5.51" and it fits fine in an 8700.
8700s and 8900s have the same case.
This thread has a bunch of different cards and some with pics in the 8700s
checkout page 26 for one of ours with the 970.
