"Unfortunately, the laptop didn’t perform half as well in games, but it's very rare to see a portable PC with decent gaming performance at this price. The G580 uses the Intel HD Graphics 3000 chipset built into its processor, but this is not powerful enough to run modern titles. The laptop couldn’t run our Dirt Showdown benchmark at our laptop settings of 1,280x720, 4x anti-aliasing and High graphics detail, showing you’d have to turn detail levels down to sub-console levels to get any kind of smooth gameplay in modern titles. If your gaming veers more towards the casual than the hardcore, though, you can always have some fun with the Windows 8 Store's 2D titles."
