How well could I run Fallout 4 with this?

Lenovo U530 Touch UltraBook: IntelCore i7 dual core processor, nvidia GT 730M graphics card, 8gb RAM, 888 gb of memory space left on hard drive. Ran Skyrim pretty well and I know it's the same engine but I wanna be sure before buying.

Not really good… The gpu will be hit hard (it needs a minimum of a 950M to play at 60fps) 8gb ram is also a min requirement.

Fallout 4 will be playable at medium settings, since the laptop has nVidia GT 730M graphics card and it played Skyrim pretty well

For good game play you want:
Fallout 4 System Requirements Recommended
-Windows 7/8/10 (64-bit OS required)
-Intel Core i7 4790 3.6 GHz or equivalent
-NVIDIA GTX 780 3GB or equivalent
OR
-AMD FX-9590 4.7 GHz or equivalent
-AMD Radeon R9 290X 4GB or equivalent
And,
-30 GB free HDD space
-8 GB RAM

Anything less, may not make for satisfactory game play.
