Looking to build a gaming rig on a budget. I need something capable of smooth multitasking, as I'm looking to start a youtube channel, so its important that this be able to easily run modern games, while recording with fraps and running some background programs like internet browser tabs, itunes, skype, etc. At stock speeds, which cpu will perform better for my needs? (This is my first computer and I'm pretty new to all this. I don't want to overclock just yet, although I might try 0.3 ghz or so on whichever one of these I get)
