3570K CPU - yes
Asus 680 2GB - I'd get two 670s .... as for AMD GFX, no way, no how on a dual GFX card capable MoBo as you have selected
As for being "overkill", the 680 gets a whopping 39 fps in Metro 2033, two Asus DC2 670s get 65 fps

G.skill 8GB RipjawsX 2133Mhz - yes, 2133 will get ya more fps, but perhaps not worth the extra cost, most popular choice is16GB DDR3-1600, CAS 9 (recommend low profile Mushkin Blackline or Corsair Vengeance)
Corsair HX850W PSU - excellent choice, perfectly sized for overclocked 3570k and two overclocked GPU's.... if not OC'ing pick the 750 watter.
Corsair 120mm H80i CPU cooler - poor choice (Phanteks quieter and better performance w/o any water inside ya electronics) ... it also tops the DH-14 in thermal performance, warranty (5 years versus 1 and aesthetics)

Zalman Z11 Mid tower case - Small for your proposed GFX.....also why "low budget" case and high end everything else ? ...... Corsair 500R combo rocks
$20 off w/ promo code EMCXSXL29, ends 4/15
$300 - $20 newegg discount - $20 MIR - $20promo = $240 for case
and PSU
Asus Maximus V Gene Motherboard - why Micro ATX ?
Suggest Asus Sabertooth (5 year warranty) or P8Z77-V PRO
Seagate 3TB Hard Drive - low warranty on new 3TB from Seagate, look at WD Black (5 years)
Artic cooling Thermal paste - not a good choice IMO ..... it takes 200 hours of thermal cycling according to AS5 website .... (a 12 hour game session = 10 minutes of thermal cycling, 5 minutes warming up and 5 minutes of cooling down) so it takes about a year if normal usage before ya AS5 has cured.
Shin Etsu is the way to go as shown in these tests

Due to the unique shape and sizes of the particles in Arctic Silver 5's conductive matrix, it will take a up to 200 hours and several thermal cycles to achieve maximum particle to particle thermal conduction and for the heatsink to CPU interface to reach maximum conductivity. (This period will be longer in a system without a fan on the heatsink or with a low speed fan on the heatsink.) On systems measuring actual internal core temperatures via the CPU's internal diode, the measured temperature will often drop 2C to 5C over this "break-in" period. This break-in will occur during the normal use of the computer as long as the computer is turned off from time to time and the interface is allowed to cool to room temperature. Once the break-in is complete, the computer can be left on if desired.
So by my estimation of this statement it would take almost a year of normal use to properly cure the AC5 compound, or almost nine days of continuous power cycles to meet their recommendation.
