I was thinking of doing that since another 780i board would cost ~$170. I would switch to the 1155 socket but, I really dislike the small choice of higher level processors, especially since so many people have them already; I would only go for a i5 2550k, or i7 2700k. Also I am waiting for ECS' z77h2-a5x motherboard to be released.
I currently have an AMD FX 8350, but I didnt like my Gigabyte 990fxa-ud5 board too much, so im selling it and waiting for ASUS' Sabertooth 990FX GEN3/r2.0
unfortunately both release dates are un-announced

I know that its a stupid reason but thats just how I am.
I really hate how you want something older, but the newer better thing is cheaper... I saw a DFI Lanparty X48-M3R_ on ebay for about $280. but theres an ASRock 990FX Extreme 9 for ~$190 including shipping on Newegg. its soo annoying.
