Do you overclock a lot? Then get the water cooling. Do you think it's worth to get a better soundcard? Then get the sound card. Depending on your motherboard, you might need another soundcard. It's not something you need, but it's something many people want. Me for instance, I don't really know if there is a difference. There might be, but I'd choose the water cooling.

Wow that is cheap. Especially the Newegg one, with SLI configuration. Unfortunately it's not available anymore, but there's another one with just the i5 in it, which goes for $819: http://www.newegg.com/Product/Product.aspx?Item=N82E16834312438

My friend had the same problem. It's like an electrical coil noise. It's nothing like coil whine, right? His problem was a faulty connection, and he sent it in for RMA and received a brand new one. PSU as well, and the brand was Corsair.

The custom ones Building your own is much more fun, than buying a pre-built one. You can also choose your own brands, which is good. Then you know exactly what's in your PC! If I had to choose a pre-built one.. It would probably be either Dell or Apple. I like the iMac (yes, it's a desktop) because of the sleak design, and Dell for making Alienware.

That power supply is way too much. You don't need that much. Why not assemble your own though? I'm sure you can make it cheaper, and it's good because you can choose your own brands. Then you don't have to worry about getting bad brands!

Running Windows on a Mac is easy. If you want to play games (as something major), then why get a Macbook?

I'm not quite sure you can get a laptop with a 780M in it, for about $1800. I know that's maybe 2/3 of the price for the laptop in Denmark (cheapest with 780M).
