Most consumer oriented laptops with discrete gpu needs a lot of care to last 3 years.They are at least 5-10k cheaper than equally or less speced business models.Business models are more expensive,usually have poor audio and gpus,BUT they are well built,have more efficient heat management system and mostly better batteries.Add to this much better A.S.S.
If you can take care of your lappy like a baby,buy any VFM gaming laptop.If you want a stable and reliable machine and ready to sacrifice latest games,look into vostros or thinkpads.
Now it is your call mate.
