So I'm aiming to build a new gaming computer, able play the latest games on the best graphics possible, and to futureproof it a bit, but I'm completly new to it. I'm also not loaded with cash, and consequently also have a budget.

Originally, it was going to look something like this:

-MSI Z77A-G41 LGA1155 Motherboard
-Kingston Hyper X Predator - 8Gb (4Gb 512M X 64-Bit X 2 Pcs) Ddr3-2400 Cl11 40-Pin Dimm Kit
-Corsair Builder Series 600W Power Supply
-i5 3570k
-MSI NVIDIA GeForce GTX660Ti or MSI AMD Radeon HD7870

But then my dad got me a Asus P9X79 PRO Motherboard second generation. Which is, apparently, good with more than one graphics card, and also worth around three times the amount of the original motherboard i was planning on buying.
So my question is: do i need to change my CPU or should i try to sell the motherboard? What is so awesome about this motherboard to warrant such a steep mark-up? I also don't really want an i7, since for gaming all it seems to do is require more money than the i5, and nothing else. Can an i5 even work on the P9X79 Pro? (I'm under the impression it can't, because a i5 is a 1155 socket while the motherboard is 2011 socket - i7 exclusive - but i really don't know how this stuff works all that well.) If an i5 doesn't work, what is a good substitute, assuming the other cheaper motherboard isn't a better option?

I'd also like to know if getting two MSI NVIDIA GeForce GTX 550Ti cards will be better for playing a single game at a time (can 2 graphics cards even work together like that?)?
2 GTx 550Ti's will be cheaper than a single GTX 660Ti or a sinlge Radeon HD7870. If 2 550Ti's don't mix well for a single modern game at a time, on ultra super high graphics, which is better - GTX 660Ti or Radeon HD7870? (or something else?)

Also, is 600w power supply too big/too small? Is there something better?

I know there are a lot of questions above, so thanks in advance. :)

A 660 TI is better than two 550 TIs in SLI. But for maxing out settings in games, you'll need a REALLY good card. 7970 or GTX 680 at least, and even then, there are some games that won't be maxed out all the way.

The 3570K won't fit in that mobo, because of the socket difference.

The P9X79 Pro is good, and good with SLI/Crossfire. The problem is that the processors that are compatible with it are expensive:

The i7-3970X is ~$1,000. The i7-3960X is ~$1,000. The i7-3930K is ~$600. The i7-3820 is ~$300 (multiplier locked).

600W should be more than fine for one graphics card.

Between the 2 graphics cards the 680 looks good to me. Is it worth it to keep the P9X79 PRO and buy an i7-3820, or should i just sell it and buy an i5 570k with a Z77 motherboard? The i5 - Z77 combo is less pricey, but will I regret not taking the i7 - X79 combo later? I'm only using this computer for gaming at this point in time.
Thanks :)
