Would it support two GTX 780?

I mean, it would run with two 780's... but the secondary PCIe slot is not a full speed slot, plus this board is from the GTX 600 series / AMD HD7000 series era so I'm inclined to say no. It would work, but your second 780 wouldn't see its full potential on only an 8X/4X slot. If you're going to spend that much money for two 780's, I'd get a board that is specifially designed for crossfiring high-end cards, where both PCIe bays can reach full 16X speed. This isn't what I'd call a high-end board.

no it will only support one of them, because it only supports crossfire but you can use a single one.

David, I SLI 2 Nvidia GTX 780 Ti's and they work like a charm with this motherboard.

Yes, but both card must be same memory and a GTX 780. Can be different makers but it 's better to use same graphic cards.

No. SLI can only be viable with 2 identical cards. The most you might be able to do is dedicate the 780 to Physx alone..but it's hardly worth the price since many games still don't utilize Physx. I'd sell the 780 and put the money towards 2 of these. Or just sli 2 780 supers. The difference is probably nominal.

Considering that on average, while running newer games on Ultra settings, I'm only using a total of around 330 watts, I would say it'll probably work. On the other hand, there's literally no reason to use two of these in SLI; even with just one I can run any new game on the highest possible settings in every area and still get 60+FPS. The second card won't do anything.

Insufficient information. There are five different video cards that can come with a stock OptiPlex 780s, so it may or may not work for you without any changes. Look on the back for two VGA ports that are near each other (blue 25-pin trapezoidal ports). If you have them, it'll work. If not, then probably not, though you may be able to make it work with a DVI-to-VGA adapter (if there's a white port next to a blue port).

Depending on what quality you want with your game. I'm just using one 780 and it plays bf4 on ultra just fine. Unless u want to do 4K maybe you will need 2 of those.

For the 780, the minimum PSU required is 650. So technically you would be OKAY, but yeah, if you want stability and better performance, then you should probably invest on a larger PSU. I have the 780 and I'm running a 750W PSU. I recommend that or an 800 PSU

I have 2x GeForce GTX 660, running right now on this computer that are tied together with SLI. Working great. Video card link: http://www.newegg.com/Product/Product.aspx?Item=N82E16814125443

Yes. With the use of an SLI bridge (usually comes with motherboard or can be bought on amazon for cheap), you can use up to 4 of these at a time. Personally, I bought one. Then another when I had the money. Two of these is 10-15% cheaper and 10-15% more powerful than a GTX 780 TI

I would check out tomshardware gpu list and see how it stacks up. You will only be able to use 1 of the GPUs since they are from different vendors.

For a single monitor I would go with the 780, if you start using multiple monitors, then I would consider two smaller GPU's. The 780 is a fabulous card, but I have two 770's right now because I use four monitors for work.

Yes, it will support a GTX 760.It will not support 2 GTX 760s in SLI. The board does not support SLI at all (although it does support crossfire), but even if it did, the 2nd PCIe 2.0 x16 slot only runs at x4 speeds, so you'd bottleneck a 2nd card anyway.

It can handle even 3 780's easily, maybe 4 if the rest of your build is not very power intensive.

Yes!It's big, though, so make sure your case can fit two of them, you have 700w or better power supply for two, and of course, that your motherboard supports it.

Yeah, you should be able to crossfire it with a different manufacturer's card as long as it's a 7970. The clock/memory speeds will be set to the same for both cards, but it should work fine.
