Any suggestions on my new rig?

Nice build  

If I was going to do anything different with that build I might do something like this below...

First the mobo. This one down below runs dual cards @ 16x & 16x like that Asus, but it hold the record o/c for these SB cpu's and is consistently the "King of the Hill" in o/c in regards to 1155 mobo's.

Dual gtx 560's in SLI > single gtx 580. These ones down below are factory over clocked and have plenty of head room to go higher...

Thanks Why_Me,

Now I'm thinking about changing the Velociraptor for a 1TB black caviar and use the spare money for a bigger SSD as you said. Any more suggestions someone?

If you're shelling out this much money for a computer, might want to consider spending an extra $20 for a DVD drive.. Depending on what it is used for you might find that having 2 drives is a HUGE benefit (if you want to rip your entire movie/music collection, for example, 2 drives is VERY convenient, especially with large collections...)
