Help on the pieces I want to buy would be greatly appreciated.

Hello, I recently decided to upgrade my mobo and my cpu because it was getting rather old. I already upgraded my Case (CoolerMaster HAF X) and my graphics card (nvidia GTX 570).
I picked these pieces with the help of my friend and I wanted to know if these are good.
CPU: Intel Core i5-2500K Sandy Bridge 3.3GHz (3.7GHz Turbo Boost) LGA 1155 95W Quad-Core Desktop Processor Intel HD Graphics 3000 BX80623I52500K
MOBO(Out of the 3 pick the best one or suggest another mobo that isn't listed):
ASUS P8Z68-V/GEN3 LGA 1155 Intel Z68 HDMI SATA 6Gb/s USB 3.0 ATX Intel Motherboard with UEFI BIOS

ASUS P8H77-V LGA 1155 Intel H77 HDMI SATA 6Gb/s USB 3.0 ATX Intel Motherboard

ASRock Z75 Pro3 LGA 1155 Intel Z75 HDMI SATA 6Gb/s USB 3.0 ATX Intel Motherboard

Also, how can I tell if a mobo already has internet capabilities?

Also, I picked these for my DDR3 Ram since I have to upgrade my RAM from DDR2
G.SKILL Ripjaws Series 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Desktop Memory Model F3-12800CL9D-8GBRL

  1. All good either Asus board would be fine.
  2. Best answer
    Only the first board is fine. It's the only one that allows you to overclock, which is a necessity with a beautiful OCer like the 2500K (or the 3770K, which you should consider). You don't have to go for trophy overclocking, going for the maximum possible frequency, but when the time for your next CPU upgrade rolls around you can just OC a few hundred mhz and have the equivalent of a whole new CPU.
    It's still pretty expensive, though. Consider the $140 ASRock Z77 Extreme4.
    Nice RAM.
  3. ASUS is the best brand in the business. I must agree.
  4. Agree on the first asus. You want the Asus that is overclockable.
  5. Thank you all for your responses
