I'm also trying to choose a mobo. It's the hardest part for me to pick.
You have to figure out what your really going to need and use.
Are you going to OverClock? Do you need a fancy Mobo with alot of options?
I am looking for just a nice standard budget board for around $150.
Set your limit on what you wanna pay, I am not to focused on AMD boards.
I have looked at that CPU before and compared it to a bit older i5-2500k (k) meaning overclockable.
This is a great site for comparing products!
AMD FX-8150 vs i5-2500k http://www.anandtech.com/bench/Product/434?vs=288&
I have choosen the i5-3570k Ivy for just a bit more money.
Post a link to the GTX 690 u want, are they the $1000 GPU's? If so that's a big waste of money.
What are you building this computer for? Making Hollywood Movies?
If this is your 1st time building a computer you don't need a $1000 video card.
I have made the mistake in the past building a gaming pc for $2100. When I could have spent $600 snf been just as happy!
