Hello RS comp guru's. You guys have always seemed to steer me in the right direction, so again I come to you guys for advice.

So now I'm in progress of upgrading. Didn't want to hijack the other threads.

I'm not too familiar with some of the new stuff. I only plan to game with this new rig. Basically prepping for BF3, Diablo 3, etc. I would like to be able to run everything at high res with good frame rates. I don't plan on spending HUGE money to upgrade.

I tried googling a bunch of stuff but the techno babble was a little too much for me to comprehend.

Here's what I have now:
Q6600 (stock)
Asus P5K mobo
4 gigs DDR2 ram
9800GTX
650W PSU
Win7 64 bit

I have ordered an Intel i7 2600K. So my plan was to get new mobo/ram. Then upgrade the GPU later. Keep the Win7 64 and the 650W PSU.

So here's my questions:

Would the new sata 6gb/s ports work with traditional sata harddrives? Or are they only for SSD's?

As for the DDR3 ram. I see some boards say they support up to 32 gigs. Maybe I'm old school but with my old stuff 4 gig's was like HOLY FUCK. I'm running Windows 7 64bit. Is 8 gb ram enough? Or 16/32 GB recommended? Does windows 7 64bit support that much ram? Is there much difference between ram? Or is it just the amount of memory all that matters?

As for motherboards. What is the major diff between a $300+ one vs. a $150 one? I assume the higher priced stuff has more ports, can run triple SLI, more RAM. But does the higher end stuff actually help the comp run faster or smoother? Does it make a big difference in gaming? What do you guys recommend for the i7 2600K LGA1155?

last Q, when I do upgrade to a better GPU (GTX560 or HD6850 unless anyone else has other suggestions). Is my PSU enough power for all these upgrades?

Thanks alot guys...sorry for the long winded post
