If you have the money then go ahead and buy an i7, an 800w should be plenty, if not a bit too much. But if your going all out, then don't skimp out on a micro atx mobo. Go full atx. there are some pretty gigabyte boards out there that will work just fine. This setup is good but the 2600k is overkill, unless you are a very serious gamer and looking for max quality. You could go for an i5, 600w psu and a gtx 550ti graphics card and you could save yourself quite a few pennies.

I think this qualifies as "building a new PC and using some spares" more than it does as "upgrade"

What is it for? Games mainly? In that case I would probably swap for the i5 2500k, and then get a HD 6970 or even GTX 580. Since GPU matters alot more than hyperthreading for gaming.
However if you do some work where you would like the "in some cases 8 things at once" that hyperthreading makes possible, then the 2600K is great.

Lastly, if you are getting one of the "K" processors you should also think about some aftermarket cooler, since overclocking on the stock cooler is usually a suboptimal and noisy afair.
The Cooler Master hyper 212 Evo is a fairly cheap one that performs quite well, but there are lots to choose from.

I play a lot of Flight Simulator X and the new Microsoft Flight that is coming out soon as well as games such as Battlefield 3 and such, I am also going to use the Alienware Stock Liquid Cooling for the CPU.

Thanks for the reply !
