Not even close. You could build something better for about $300 less, or $400 if you're willing to overclock.
Check out my $1000-1100 build here:http://www.squidoo.com/electronicandmore
The i5 3570K after an easy overclock is good enough for gaming. i7's are for people who are going to do heavy multi-threading and I'm assuming you're just gaming.
That motherboard is a ripoff and all ROG's will always be for consumers who don't overclock like with Liquid nitrogen or something. ROG performs like normal $130-$160 boards.
580 is old, the 7870 performs better than it for less and it's quieter, faster slightly, lower power consumption and less heat.
RAID SSD is not so good for the SSD life span.
H80 is a ripoff the Hyper Evo and A70 match up to the H70 which is $35 more than the listed air coolers.
