New Gaming/Video Editing PC

Hey motherboarders,

I am thinking about building a new gaming/video editing computer. So the parts I am thinking of:

Case: Cooler Master Elite 430 Mid-tower
CPU: AMD Phenom II X6 1100T
Ram: 6GB DDR3 2000Mhz
GPU: SLI GTX 470s (2)
PSU: To be determined
Mobo: To be determined

Now first off I would like to know what you guys think I should look at for a PSU and Mobo. From the first glance of searching I didn't find a good AMD board with Nvidia chipset. From what I understand I will not be able to run SLI on a board with ATI chipset unless I use a cracked driver (or something like that) which I do not want to do.

I have no clue about PSUs. I don't know whats good and whats not. I was thinking a 700-750w?

Also I chose that case because I am not a fan of full towers. I don't have room for one and to be quite honest I think they can be an eye sore. I like that case because I can fit the longer GPUs and it has great air flow.

Anyways what do you all think?

  1. 6 gigs of ram is for i7s, not amd cpus... Get 8 gigs of 1600mhz g.skill.

    Correct on the sli, go for ati, maybe 5870.. I think there are 2 boards that support sli... But even that is glitched...

    You only need around 650 watts if it is certified, I always say to get bigger so you can upgrade later on...
  2. A quality modern PSU has full range active PFC (no little voltage switch) and 80+ certification. Antec, Seasonic, Corsair, XFX, and Enermax are among the better brands. For a pair of GTX470s, I think 750W would be a good size.
    Based on the PSU calculator at , you could use 650W, but you'd probably be outside its most efficient operating range.
    For a high-end build, take a look at Sandy Bridge. It outperforms AMD by a sizable margin, and most LGA1155 mobos support both SLI and Crossfire.
    I would not attempt to SLI a pair of HOT GTX470 cards in that case, no way no how. If you want to use that case, get a single GTX570.
  3. Thanks for the input guys.

    For the GPUs, I am planning on add Zalman coolers on both to help with the heat. Also with 3 intake 120s and 3 exhaust 120s the case should vent the heat pretty well. Either that or I will just get a single GTX580.

    As for the PSU, I will probably end up getting a Corsair 750w.

    As for as the CPU, I am dead set on AMD. That is what I have always used and the Intel's are just a bit out of budget (at least more than I am comfortable with).
  4. The Coolermaster Elite 430, does not have that many usable fan openings (a long PSU will block the bottom one), and only comes with two fans. Although it has a bottom-mounted PSU, it has no cable management. I don't think you should try to SLI two GTX470s in it.
