I saw someone post about overclocking the cards for MSI.

These are gigabyte cards, will the MSI program work for these or is there a program from Gigabyte? Is there a tutorial on this somewhere?

Also the comment regarding the lowering the voltage, is there a tutorial on this?

Yeah, but those aren't available for sale almost anywhere. Yet. I'll stick to what's locally available. I see we have MSI-990FXA-GD65 where I am, so I can go with that.

You can mine with different cards, no problem.
It has no metter if you use pci-e 3.0 or 2.0., for mining you don't need even pci-e 16x slot, it's good with 1x too, just need powered riser for that.

Can I ask, all new high end video cards for GPU mining can use 1x pci-e slots? That means it's the short connection? And all GPUs can use powered risers that fit pci-e 1x?

So I can use almost any motherboard that has a bunch of pci-e slots, because the smallest one is 1x anyway?

Yes, but use powered risers for 1x slots because we've seen a few motherboards set on fire because they weren't expecting a graphics card drawing 75w from it!  Shocked

There are motherboard designed for the task though check out http://www.asrock.com/news/index.asp?cat=News&ID=1765

I am mining for a hobby so please do critique me for mining with a GPU (I know GPU mining is dead but I want to try it anyway), but I have 2 GPU Radeon R9 290 and 2 GPU Radeon R9 290x both made by Gigabyte, Can I put both of these into one mother board and mine or do I have to connect them to two different mother boards because they are different cards? Simply put can a person build a mining rig with two different GPUs?

Also on the motherboard is there any difference in speed between a 3.0 and a 2.0 connection for a pci connection?

Thanks in advance
One advice though: give yourself a favor: switch to mining litecoins instead of bitcoins. You can exchange them later to bitcoins if you wish, but mining litecoins is ~26 times more effective than mining bitcoins. I am sorry that I switched to litecoins late, just wasted a lot of time.
You will need just change a little bit the command line or config file of your miner.

Yep different cards is not an issue use Afterburner to overclock both cards separately. http://www.youtube.com/watch?v=wMWb5SlSgfU

We still use GPUs to mine Litecoin, so don't worry we don't think you're a fool, unless you want to mine Bitcoins that way!  Tongue

make sure to grab msi afterburner to overclock them. You can oc each card to squeeze a bit extra out of each card, free and easy extra hashing

you might want to undervolt them a bit too so they run a bit cooler
