Safe to Game on a MacBook Air?

Hi.

I have a MacBook Air Early 2014 and I was wondering if it is safe to use it for gaming. I've installed Windows on it with Boot Camp Assistant and the specs I see for the Mac are:

• A 1.4 GHz Dual-Core Intel Core i5 processor
• 4GB 1600 MHz DDR3 RAM
• Intel HD Graphics 5000 1536MB

The recommended specs for the game are:

• Pentium 4 3.0GHz+ processor
• 2GB+ of RAM
• Graphics: ATI Radeon HD or higher or Geforce 7 Series or higher
• Sound Card: Any DirectX 9.0c compatible sound card

Obviously there is enough RAM, but I worry about the processor being too slow — I'm not sure what the 1.4GHz means, it doesn't seem enough. I'm also not sure about the graphics card. Should I buy a cooler to deal with overheating? I expect the Mac to overheat since simply browsing while running Windows turns on the cooler sometimes.

Thanks!
