This gives you an option of adding a second 580 for SLI in the future, but you should upgrade your PSU to a 850w before that.
Did you need a monitor? If so, then you should remove the CPU cooler and downgrade the 580 to a 570 to get one.
what zhongyan suggests is fantastic
the only thing i could add on his build is that you have the option to go a little lower on the ssd, like 30gb and have it caching instead of a boot drive. It will be slower overall performance but it will allow you a better cooler.
It is just that 60giga is too little for me and i am thinking either go 120-128 giga or have it caching. Better aftermarket cooler nets higher OC results. I could be wrong in which case someone with knowledge on the ssd just for cache matter could enlighten us all.
