Default Re: Thinking of building this! Would like some feedback

The high-end AMD graphics cards are due in January according to rumors so that is only a two month wait or even one month if they come out early January.

This is what I've planned now:

Processor: Intel Core i7-3930K ($599.99)
Cooler: Corsair Hydro Series H80 ($93.99)
Motherboard: GIGABYTE GA-X79-UD3 ($269.99)
RAM: 16 GB Corsair Vengeance DDR3 1600 MHz CMZ16GX3M4A1600C9 ($89.99)
Graphics card: 2 x XFX Radeon HD 7970 ($699.98?)
Sound card: Creative Sound Blaster X-Fi Titanium HD ($139.99)
SSD: Intel 510 Series 120 GB ($275.00) or Intel 520 Series if available by the time I buy
HDD: Western Digital Caviar Black 1 TB WD1002FAEX ($79.99?)
Optical drive: Sony Optiarc AD-7261S ($19.99)
Power supply: Corsair Professional Series Gold AX850 ($183.99)
Case: Corsair Obsidian Series 650D ($189.99)
Monitor: ASUS PA238Q ($274.99)
Speakers: Corsair Gaming Audio Series SP2500 ($199.99)
Keyboard: Microsoft SideWinder X4 ($42.77)
Mouse: Logitech G9x ($59.99)
OS: Microsoft Windows 7 Ultimate


1. Will an H80 be good enough to cool an overclocked 3930K or should I swing for the H100? I know that the 3930K is not exactly a cool running CPU.

Well, what are you hoping to OC to? Yes an H80 will be enough to cool an over clocked 3930K. Will the H100 *possibly* allow for a higher OC due to lower temps? Yes. Notice I emphasised "possibly". As always OC'ing is not a guarantee- there are other variables such as MOBO and RAM that play a big part in a units over all over-clockability.

2. Will the AX850 be enough to power this build?

I don't see why not. If you're worried about it and can afford it jump up to a 1200Watt PSU. Single or Quad Rail recommended of course. I've been using my 850Watt PSU since mid'06 so over 5 years now. Ran dual 8800GTXs without a problem and those things were far from energy efficient. I imagine the 7970s will be much more power-friendly than the top-tier G80 was so I'd say even running two of them you should be fine. But again, if you are concerned about it just bump up to a 1KW or 1.2KW PSU. If it's from a reputable vendor like Antec, Silverstone, SeaSonic, OCZ, etc you'll be fine- but just check the AMPs on the 12v rail(s) just as a precaution. Likely at that wattage you'll be more than sufficient but always a good thing to check just in case.

3. What happened to the Intel 520 SSD? Rumors were saying early November release date.

Oooh... good question- I've no idea. I don't follow SSDs too closely but I know Slawter does. Maybe he'll be able to chime in here.

4. Is it better to get two HD 7970 cards in CrossFireX or a single HD 7990?

There is no "yes" or "no" answer here. It strictly boils down to preference. So the right question is "Which would you prefer- two HD7970s or a single 7990"?
See bold.
