Real novice gamer trying to build my first system here asking for advice...both of these builds are within my budget, but don't know which is better due to the socket differences. Please help...any advice would be appreciated!

Is there a special reason you want liquid cooling right from the start. You could build a much simpler/safer air cooled system now then upgrade to liquid cool later if you find you want to.

Both systems have twice the power they need. Even leaving power for a second GPU they only need 750W.

I dont know of anyone building their own system that uses intel montherboards. I would look for an ASUS or EVGA p55 motherboard instead.

Kinston is a cheap junk RAM manufacturer, look for Corsair, GSkill, OCZ, even Patriot instead.

Socket 1366 is not being phased out. It is the high end socket and intel's 6 core CPUs will use it. The 1156 is the economy socket which you see more of because it was just released and it is a good price/performance value.

Dual HDDs in Raid 0 isnt going to help your gaming performance much. It only helps when you load new maps and such, not while you are playing.
 
Good advice here.
I agree, get a good Heatsink/120mm fan combo for your CPU. Get another 120mm case fan (low noise) to push out the air.

HD5870:
1) The Vapor-X version is going to be released by Sapphire
2) I'd hold off for the NVidia cards due before Christmas

CPU:
i7-860

MOBO:
1156

RAM:
4GB DDR3 (2x2GB)

PSU:
650W/750W good quality

There are pros and cons to going with the 1156 vs 1366 platforms. The 1156 is slightly cheaper but also the IDLE power is less than 1366 (it's the best at this power level period). The 1366 has 2x the theoretical PCIe bandwidth (2x16) however it's been shown that you can run 2xHD5870 on the 1156 without being limited by PCIe bandwidth. The 1366 does have the advantage of Memory bandwidth but again real-world performance for most people would be nil. I know the 6-core 32nm CPU is going to the 1366 but I'm sure the 1156 will get something by the time it's time to upgrade.

Other:
- SATA 6Gb/s ?
- sound ?

If you want to compare 1156 to 1366 there are lots of reviews. The bottom line for me is the Idle power (and performance). The HD5870, i7-860 and 1156 are an unbeatable combination.
