Console gaming (XBOX, Playstation, Nintendo, etc) or PC gaming.
Dave wants to know why he can't watch YouTube in larger resolutions through the PS3. He only gets 240. Leo says that's ugly. The issue could be bandwidth. But what Dave may want to do is use the app, and not the browser. You can download the YouTube App from the Sony Playstation store. That will always do better than the browser.
Devon wants to get an iBuyPower Gaming PC. Is that a good brand? Leo says that iBuyPower makes great computers and at $495, it's a great deal. The games that Devon wants to play aren't really all that demanding, but still, it depends on what graphics processor and card he's going to get. For video games, the GPU is the workhorse. The NVidia GE Force GT610 is a good one.
Jennifer would like to record video from her Nintendo 3DS and post it on YouTube. Leo says she can get a 3DS capture board which can then route the video signal to her PC to record, edit and upload. This requires an original 3DS to work though, so be aware of that.
Ivan is a hardcore gamer and he uses an Alienware laptop. But his laptop has been getting up past 200 degrees. Leo says that's not a good thing. It's normal for a laptop to heat up with a lot of hard core use, but not that much. Leo suspects that Ivan's GPU fan isn't working. It could also be that the thermal paste wasn't applied correctly. Leo advises going back to the store with it and having them fix the issue.
Joshua owns and operates Minecraft servers and he wants to know what the future has in store for online gaming. Leo says that since Microsoft bought Minecraft, it's possible that Microsoft could require Minecraft be run from Azure. But Leo doesn't think there's much cause to worry because the Minecraft culture is very independent. Gamers won't really feel Microsoft's presence in Minecraft for at least a year, but there's not much cause for concern. Since online gaming is social by nature, the future is bright.
Diego plays a lot of multi user online games like League of Legends. He has a 2013 MacBook Pro, but he doesn't know how to stream his game play. Leo says that Twitch is a good utility for that. Most people who stream are using PCs for that. He can also do it via the PS4 or XBox One. But for the Mac, Twitch has guides that can help, so Leo advises going there and reading up.
Paula wants to know the best place to buy a gaming computer for her son who does gaming videos on YouTube and Twitch. Leo says that kids get real serious with their computers and having the best computer she can afford will give him the tools he needs. But gaming computers aren't cheap. All PCs can game, but gaming computers use higher end components that can really give her sticker shock. They require a dedicated GPU.
Michael says that this year is the 30th anniversary of Windows. And he says he thought it would be cool if Windows would give users the ability to "skin" Windows back to the original Windows look to celebrate. Leo says that they did that for Windows XP and he hated it. But it's just software, so he could. Microsoft wants to push users forward, and as such, they're annoying users with their heavy hand.
