I'm no expert but I can help out a bit too. As a starter I'll tell you my laptop specs:
Intel i7 2.4 Ghz
6 GB RAM
1 TB ROM
Video Memory 3.1 GB
Intel HD 4600
AMD Radeon R7 M265 Series
Mine runs fine and smooth, though due to some mods I need extra RAM. For now I can say these are average gaming specs. New Vegas Vanilla runs fine especially with the unofficial patches and few fixes like NVAC(Anti-Crash) and No Stutter mod.
If you got doubts follow what Evmeister said. No harm checking the device manager. I hope that helped.
No matter the circumstances, no matter what happens around me, I never rely on luck. Because in life there is no such thing as luck, but the knowledge for advantages. In other words, we make our own luck.
