I currently own a X51 R2 that I haven't really touched in years (5+) since going to school. I've come back with a new appreciation for gaming but I didn't know much myself prior.

What would I need to update in order to make this machine run current gen games smoothly? (60fps, 1080p?)

My model is the D05S (?) Not quite sure.

Or would I be better to try to sell this off and buy something else? What could I hope to salvage this for?

Any help would be appreciated!
