Need advice on a motherboard (2500K/HD6950)

[slypenguin0]

Hey all!
Thanks in advance on any and all help. I've purchased everything but a motherboard. I thought I was sold by all the praise on the Asrock Extreme3 Gen3 until I noticed it didn't support USB3.0 on the front panel. I've done a bit of research on the Asrock Extreme4 Gen3, ASUS P8Z68-V/Gen3 (so many versions), MSI Z68A-GD65-G3, etc. Some help from you folks would be appreciated.

Approximate Purchase Date: Whenever. It's the last part I need.
Budget Range: $100-$205 (unless you can convince me that a board for like $230 is absolutely necessary lol)
System Usage from Most to Least Important: Gaming, simple video/audio/photo editing, streaming, surfing
Country: USA
Overclocking: Yes. Probably not going past 4.5ghz. Not sure if I want to OC the ram just yet.
SLI or Crossfire: Yes - in the future. I wont be using more than 2 GPU's.
Monitor Resolution: 23"1920x1080 (would love to have 2 monitors in the future)

What I have already:
Corsair Carbide Series 500R White Steel structure with molded ABS plastic accent pieces ATX Mid Tower Computer Case
Core i5 2500K LGA 1155
COOLER MASTER Hyper 212 Plus
1 x CORSAIR Vengeance 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Desktop Memory Model CMZ8GX3M2A1600C9R
MSI R6950 Twin Frozr II OC Radeon HD 6950 2GB 256-bit GDDR5 PCI Express 2.1 x16 HDCP Ready CrossFireX Support Video Card with Eyefinity
1 x OCZ Vertex 3 VTX3-25SAT3-120G 2.5" 120GB SATA III MLC Internal Solid State Drive (SSD)
Old Seagate 300GB Sata drive from current computer (Don't laugh)
USB3.0 1TB External HDD
SeaSonic X750 Gold 750W ATX12V V2.3/EPS 12V V2.91 SLI Ready 80 PLUS GOLD Certified Modular Active PFC Power Supply

Thanks again!
