AMD Athlon II X2 240e Processor


Home Theater PCs have been all the rage in recent years.  As people turn more and more to internet-based services like Hulu and NetFlix to get their entertainment, the demand for devices that can handle all that media and stream it to your TV has shot up dramatically.  While many pre-built set-top boxes exist to fill this niche, they often leave much to be desired.  Limited format support, limited storage space, limited choice of media services; too many of these boxes leave you wanting more.  Also, none of these boxes allow for gaming, beyond trivial games like Peggle or Bejeweled.

This is where the DIY home theater PC comes into play.  You choose how it looks, you choose what goes inside, and you set it up to do just what you want, and nothing you don’t.  Building a HTPC on the cheap is fairly simple, but it needs a good CPU to do all the things you want it to do.  Enter AMD’s Athlon II X2 line, a series of cheap, low-power-draw CPUs that are aimed squarely at the budget PC and HTPC market.  Today we’ll be looking at the Athlon II X2 240e, one of AMD’s most economical offerings in the Athlon II line.
