After two quick listener mail questions, we introduce a special guest to the TR Podcast: Jeff Atwood, author of Coding Horror and the brains behind Stack Overflow and Discourse.org. Jeff is one of our top 10 contributors, and he's also a former TR writer who once did some development work for the site.

After we catch up with Jeff, Scott and the team discuss Intel's refreshed Haswell CPUs. Then, Scott provides a deep dive into the Radeon R9 295 X2 GPU and the current state of 4K gaming. To finish off our episode, we discuss Samsung's 28" single-tile 4K display, and Cyril pontificates about Valve's Steam controller.
