I am building a new system. Budget is not the issue performance for what I need is. I will mostly use it for video editing (Canon 7D camera) and photo editing. Sometimes I have to do the rendering of the video and the photo editing at the same time. Here is my system that I think to build:
1. Asus P9X79 WS or Intel DX79SI
2. Intel Core I7-3930K
3. Corsair H100 CPU Cooler
4. AMD Radeon HD 7970 or GeForce GTX 680 PCIE SC+
5. Coolermaster HAF X
6. Coolermaster Silent Pro Hybrid 1300W Power supply
7. Corsair Dominator 4x6GB DDR3 SDRAM
8. Seagate Barracuda 3T
9. Intel 240GB SSD
Right, well people can correct me, but I can advise you in some way. Firstly, lets start with the RAM. That RAM, someone will have to check me on it, is meant for triple channel memory, which probably isn't compatible with your motherboard or CPU (because i've only found 6x4Gb dominator sets). So I suggest going for either the 16gb or the 32gb option of RAM, because it's easier to find, there's a greater variety of those kits available, and from what i've seen and read, your motherboard will be happier (don't actually know the validity of some of those forums, but meh).
As motherboards go, I don't think you need all that expansion space, ahaha, so I'd say go for one of the rampage boards, like the Formula.
Now for the PSU, 1300W is waaaaay too much, especially for your set-up, i'd say 1000W at most, but even that's pushing it. If you do want head-room i'd say the 1050W corsair HX series, but look down for your PSU wattage, not up.
Finally, the GPU's. Well, that's a bit cruel what you have there, sock-pcb HD7970 versus a stock board, but custom GTX680.
For a 7970, the gigabyte 7970 GHZ OC is a great place to start. I'd only recommend the 7970 if you are overclocking or having a multi-display set-up, where the extra bandwidth shines. If not, the 680 is the way to go (me I use the 7970 and I video edit, photo edit and 3d model on C4D, with one monitor, but I just love overclocking).
However, I would recommend a custom PCB 680. The Gigabyte 680 OC is a brilliant card that is quiet and runs really cool.
Hope I helped in some way. Anyone else can come in and amend what I said, I don't claim to be a guru, just saw this forum and decided to help out best I could.
isn't 750W a bit low since both cards will use at max 500W at certain times? I might add a video capturing card at a later time plus a 3D sound card if the motherboards option is not as good as i would like it to be.
Personally, I wouldn't get a 750W, more like an 850W or higher (but not above 1050W) PSU. Also, soundcards draw relatively no power, typically only 10-15W for a dedicated soundcard. A video capture card also doesn't draw too much extra.
It's not the most accurate, but using a PSU calculator I came up with about 616W for you, although headroom is good. 750W could prove to be enough, but if 850W will give you peace of mind, I'd recommend that.
A 750W power supply is enough to run 2 GTX 680's, especially a Corsair 80 PLUS Gold. It's your money though, you can get an 850W.
Yep, I got about 747W for a SLI 680 set-up on the calculator...a little close for a 750W powersupply, as they don't always run at peak given ambient temperatures, manufacturer and even PSU product (some *ahem* 'lie' about actual wattage, with some PSU's only being about 730W instead of 750W, or ~820W instead of 850W)
