Would a Core i-series really provide that much better performance or efficiency? For the same wattage there's only the i5-3570T at 2.3 GHz versus 2.6 GHz. (I can't even locate a unit for price comparison.)

I think the point is that a "lowly" dual core i3 with hyperthreading is faster in essentially everything (including video encoding) compared to the quad core you chose and uses less power as well.

That's why folks keep recommending Ivy Bridge processors.Waco wrote: A "lowly" dual core i3 with hyperthreading is faster in essentially everything... and uses less power as well.

If you're not going to install a dedicated graphics card for gaming, then an A10-5700 APU on a socket-FM2 motherboard might be a good choice.
If you're going to play games or use a cablecard tuner, you need Windows 8 64-bit, Windows 7 64-bit or Windows Vista 64-bit for this system.

If you're using integrated graphics, increased memory bandwidth can provide a measurable increase in performance. If you're using a dedicated gaming graphics card so that the CPU isn't competing with the IGP for bandwidth, there's much less difference.Waco wrote:DDR3-1066 versus DDR3-1600 versus even DDR3-2400 isn't going to make much of a difference in normal use...most applications aren't very memory-intensive.

If a Phenom II X4 850 is being burdened so much with both a game and transcoding a prerecorded video, I doubt a 620e with less processing power could handle a game and recording a live stream simultaneously.
Unfortunately, I'm having absolutely no luck finding power consumption for CPUs with integrated video disabled. (I find the lack of search results baffling.) I thought it was covered in some of the Tech Report benchmarks, but I'm still not having any luck. Honestly, I'm feeling rather overloaded with information at this point.
[EDIT] Is ECC memory something recommended? I vaguely recall it having a performance penalty, but I'm not sure if that's true any longer. I'll need to look into prices.

It's a bit frustrating reading that over and over since I went there to find out in the first place. I guess I'm looking at the wrong articles.
chuckula wrote:Intel puts up that disclaimer because even if its chips support those features, they also need to have motherboard support and there is not guarantee that your motherboard will provide support for those features. In general, if ARK says that a chip supports or doesn't support feature X, then you can be confident that the *chip* does or does not support that feature. YMMV on motherboards though, and that is really beyond Intel's control in many situations (the exact same situation applies for AMD chips too).
