I need a new Motherboard

So,

I made a great move and bought a second gpu without checking if my motherboard had enough space for it, it did not. Impulse buying ftw...


These are my current specs:

Tower: Haf X Full Tower
MB: Gigabyte Z68XP-UD4
CPU: Intel Core i7 2600K
CPU Cooler: OCK Frio
RAM: 2x8GB 1600MHZ Corsair Vengeance
GPU (1): XFX 7970
GPU Cooler (1): Accelero Xtreme
GPU (2): Gigabyte 7970 - Currently not installed due to lack of space
Sound Card: Uses a x4 PCI-e slot, but can use x8 or x16
PSU: Thermaltake 800Watt

I keep making mistakes, I've had a couple of motherboards fail on me, essentially I want something that will allow for Crossfire and have a decent amount of room between the GPUs. I don't mind if the sound card has to sit in between.

Another thing is the RAM, in my current build I have to have them in slot A and B due to the cpu cooler covering the first 2 A and B slots. I would like to be able to run them in dual-channel.

I also do overclock.

Any suggestions would be great.

If you need more info just post and I'll answer ASAP.

Price is always an issue but I am willing to spend if I can be guaranteed it will be worth it.

Thanks.
