^ The list of components are good, but you can save money with these changes, without loosing much of features or performance...
1. Check out this mobo...has sufficient BIOS options for a very good overclock and has good layout...
EVGA 141-BL-E757-TR LGA 1366 Intel X58 ATX X58 SLI LE

And just a suggestion...For the price of that GTX 260, you can get a HD 4890 for about $10 more...But not much of a difference for that resolution though...

And GTX 260 SLI is not a good option to consider as newer Direct 11 cards are coming...So that time, instead of buying another GTX, invest in them...
Hope this helps...
Since you are going with the Antec 1200 Case you will need this 8-pin Power Extesion cable for Bottom mounted Psu cases. Otherwise you will have to run that cable across the length of mobo.
