Hi all--I'm looking to upgrade my XPS 8100 to play Fallout 4. It's out of the box with now modifications. I found online that the following were recommended, but no confirmation that these are actually 100% compatible. Can anyone confirm that these will work with my system and will actually fit, measurement-wise? Also, this seems like a pretty heavy duty graphics card--do I really need something this expensive to run Fallout 4? Will the CPU on the XPS 8100 (Intel Core i7 860 @ 2.80GHz) bottleneck it?
Thank you!
