Meh, they just use that keyboard because it has a LCD that be set to show CPU consumption. You can do the same with general-purpose I/O ports like USB/EIA232 and a serial LCD display if you're into that sort of stuff. Another 8GB of RAM can vary greatly in price depending on the rated speed. Pricewatch.com has street prices to compare. $40 to $80 depending on the speed which is enough to get a game or get a bigger drive or save for later upgrades. Talk about old - see this 2009 thread that oddly enough seems to cover RAM bandwidth math pretty well.
If you have 2 CPUs each with the same MHz, cores, and stepping, but one has a faster external bus, then the one with the faster bus and lower multiplier is the better CPU. For cases where you have say, a 10% increased bus speed on CPU B but CPU A has a newer stepping and 10% higher clock speed, it gets 'complicated'. The pain of it, is that you can have the bottleneck in the GPU or the CPU or the RAM or the HDD or... (It's most likely in the GPU/CPU/RAM) And it may only be in one specific game that you hit the GPU, but another game might hit one of the OTHER 2 limits.

Avoid the Sandy steppings and get the Ivy Bridge steppings if you can. For the same GHz, you'll find that it runs cooler and uses less power and DOESN'T MAKE YOUR CPU FAN SOUND LIKE A JET PLANE. That is, assuming that your CPU fan slows down when not needed at full speed (they all do this unless the lowest-end cheap P-O-S, now). I'm sure XBox 360 owners know all about this one, hehe. It's annoying to be playing a movie or something and you can hear over theTV sound system.
If you run a PSU at or near it's thermal rating (and not just the peak rate that the electronics can handle), then you're asking for trouble. The problem is that most power supply ratings are like apples and freakingoranges dogs. Lies, damn lies, and power supply ratings. But at least you generally get what you pay for. A $20 '650 w' power supply and a $50 '500w' power supply - guess which will work better when your system is drawing 350w average and 500w while in your game? Of course, if you see a tiny and lightweight power supply with one tiny fan and another with an average weight and 2 big fans, you can tell which will likely last, no matter what the price difference is. Here's the general guide line if buying a decent power supply: Calculate the HIGHEST amount your system will use and then multiply by 1.2. Get a power supply there and you won't likely burn your house down.
http://extreme.outer...culatorlite.jsp Just for the heck of it, I put a dual-GTX590 and single-CPU i5-680 system into there and got 757 watts with 807 watts recommended. Haha, that would be a kick-ass system. And for an insane build, I got 1200 watts recommended for dual-GPU, dual-CPU GTX590/E5-1660 with 8 RAM modules, 4 15K RPM drives, liquid cooling, and both a RAM SSD and Flash SSD. Too bad the calculator doesn't cover the newer stuff but it is pretty easy to use.
