I already mentioned this in a bunch of other computer threads but if you live near a store called Microcenter, they will literally sell everything for a stuffload cheaper. The 3570k @ Microcenter is $189 (even though the newegg one is $199, it will only last until 10/26). Total savings would be around $200-$250.
other than that though, maybe you should downgrade your videocard to a gtx 660ti and get a better mobo+ case?
