My gaming laptop is a few years old now, so many games don't run on it very well. I tend to buy lots of games on steam at discount, so if something doesn't run well it's not a huge waste of money, those games sit there in my account and I'll eventually get to play them when I replace this PC.
Still, that's a shitty way of buying games, especially because more and more games will not run on this box. How do you guys figure out if your machine meets the minimum required specs listed on a steam store page?
In particular the graphics card stuff is a mystery to me, if a game says the minimum required is for example "NVIDIA® GeForce® 9600GT, ATI Radeon™ HD 5870", how do I know if my laptop GPU is better or worse than those?
