= $1635,91 + $100 shipping you would still be way under your price with nearly as much performance (but thats only really because of the GPU, everything else is same or above)
Down below you can read up on my opinion on the parts that i would choose if i had your budget or had to built my setup all over again.
CPU: Is plenty for gaming and brand new
Mobo: Asus RoG as always the best of the best, looks good performance and style wise.
GPU: The Matrix Platinum series only applys to the top end of each GPU generation and is hand picked out of the best 7970"s. Out of all Gpu"s it uses the BEST components and offer"s the HIGHEST clocks right out the box and on top of that it is the ONLY card that cools literally everything on the pcb. For a more indepth view check out the following review http://www.techpowerup.com/reviews/ASUS/HD_7970_Matrix/4.html
Ram: 8GB of 1600mhz is plenty for gaming, you dont need 16gb (even next gen will be designed around 8gb) and higher mhz has zero impact performance wise on most games.
PSU: 760 watt platinum is enough for your setup and one more top end part in this build. The psu is the hearth of each build and you really shouldn"t cheap out on that. Fully modular you can even buy individual sleeved cables on Corsair"s website if you so desire to.
SSD: I choosed the Samsung 840 Pro 128GB since its one just one of the fastest SSD"s out there. I did not choose any HDD since i think it would just slow you down. If you really need the extra space you could pick up the 256GB version which would grant you a higher writing speed (up to 520 mb/s instead of 390 mb/s)
Cooler: The Corsair h110 has really good performance but you would need enough space since it is designed with 2 140mm fans. I dont know if the case you choosed has space for it, but the case i did choose has it. Alternatively you could ofcourse get the h100i if you stay with your case.
Case: I did alot of personal research and none out of probably 200 cases did provide the mobility and space like the c70 did. You can easily transport it around thanks to the grips, has a huge window, has tons of room for cable management and on top of that you even could install up to 4 radiators.
Optical Drive: I did not choose a optical drive since i really think its no longer needed in 2013. If you still need a drive, you can take the one you already picked.I hope that cleared your questions up quite a bit and that i could convince you in some (if not all) categories.Edited by Takla - 6/11/13 at 8:31am
