You don't want that RAM with those tall cake cutter heat spreaders unless you plan on using them for a hair comb. The serve no purpose other than to impede any decent sized cpu h/s. Also no need for an 850w psu for two of those cards in SLI. 750w gives you plenty of headroom. And if this is a gaming PC then go big on the SSD seeing how it's in your budget. SSD's are dropping in price just about every other week now so by the time you purchase they should be even cheaper.
