My lenovo y510p is pushing like 3 years old and still going strong. No hardware failures other than the keyboard keys being mega faded and it runs almost everything I currently play at 30 or 60 with at least medium settings which is making it hard to bite the bullet on an upgrade but I think I should start looking at some newer laptops.
What GPU do you have?
It really depends on what type of games you play. If you stick to indie, strategy, world builders (Terraria, Minecraft, Starbound) you really don't need much to get by.
Now if you want to play the likes of The Division (or any Ubi game), you're going to need a capable piece of hardware.. Games like Deus Ex: MD can run moderately on older hardware, while Gears of War 4 would run terribly.
I could get by until next year. I have a 7970m, PC is not my main platform, and I don't play many FPS or graphically demanding games (outside of say The Witcher 3, which runs around 34-48 fps for me, still better than PS4). I guess, I just want something shiny and new. It has been three years, and my card isn't in the same class of a 980m. . Nothing is wrong with my Sager, other than needing a new battery, and the backslash key next to the space bar needs to be replaced (being held on by tape)
