@ Murfmurf - Sure Kingston is an option for RAM, and Palit is a GPU option too
@ Huberto - You don't need to underline stuff to make it stick out
Intel's Haswell will only offer 7% performance increase over Ivy Bridge according to Anandtech's recent review on it, so not exactly something you need to wait for. Concerning the energy saving nature of Haswell, I'd expect it to not over clock as well as an Ivy Bridge (just like Sandy Bridge could OC better than Ivy Bridge), so if I'm right on this then there is nothing wrong with getting an Ivy Bridge. Again, this is called building a PC in anticipation for Rome 2, and I'm one of those guys that can't wait to build his PC for Rome 2. And I am aware than Intel will not drop their prices, they never have and never will, they have a tight choke on that.
But why are you suggesting Nvidia? AMD is currently the king of the castle, maybe not king of highest throne (Titan owns that), but their $300-$400 cards can beat Nvidia almost all the time in gaming.
So yeah. Haswell is designed for the mobile platform primarily, but has taken over those advantages to the desktop ie. more efficient power usage, less power usage, better integrated graphics. It also gives Intel the chance to upgrade their existing desktop platforms for new technologies coming in, because it would be strange to see Intel laptop with more advanced features than their desktops, no?
EDIT: Also, with Ivy Bridge currently at the end of its road, all the hardware developers have finished developing what they have for it, so what is available right now, is all there will be, no need to worry about any upcoming new motherboards to wait on, or RAM specifically engineered for the 7ZZ platform. But then if you get the upcoming Z87, your getting the very beginning of that market, something that will develop for a lot longer. In my opinion, I would go Z77 over Z87 for this year.
