If you are setting up a GPU (Graphic Card) mining rig do they have to be the same GPU (Graphic Card)

 Can someone answer this question for me?

Please start this topic at the altcoin section where it belongs.

Bitcoin mining today is done with ASIC hardware, like for example Antminer S9, AvalonMiner741...

No, they don't.

 No, they do not need to be the same card.

 Same MODEL of card will tend to be more stable though - as in run all R9 290, or all RX 470, etc, instead of mix-and-match.

Its about the gpu mining. So its not asic...

Its also ethereum mining and there is no asic miner for that yet.

Way more convenient with tweaking. I have one rig with XFX 480's. Some are black edition and some are not. I am at the point to either sell off the non black edition or set up a seperate rig for them. It's that frustrating to set them up in one rig. However if you plan to leave everything in stock settings you should be fine.

So If i had 6 random gpus will it make a difference.

Also if i had 6 Radeon 480 8gb different brands and stuff what will happen then.

It's not a problem to mix and match brands and models. You will need to find the sweet spot for each individual card even if they are all identical anyways, so there's nothing to be lost by mixing different models together. Sure if the price was the same I would always buy the same GPUs, but if I can save $100+ by shopping the sales and rebates I'll go that route.

Understood so my next question is that I have a rig with 5x SAPPHIRE Vapor-X Radeon R9 280X and I want to add a 6th card. I'd like to add the most powerful card that has a good ROI still however should I simply add another SAPPHIRE Vapor-X Radeon R9 280X? I'm sure I could find one for a decent price?

[Jdope]

If you want the most powerful card then you can get a 390, it's much more powerful than the 280x

They are powerful but depends what you want. If you don't pay electricity or if it's low per kwh then they are best option. If you are paying then the best option is rx 470 or 480

[klaaas]

If you are paying then the best option is rx 470 or 480

Correct, A rx 570 or 580 could also worth to consider.

My elec. is semi high based off the prices I've read others have at .14c kwh, my main concern is the conflict of it potentially not being recognized on the rig

[RentGPU]

You can mix diffrenet brands like msi,gigabyte,xfx..etc it won't affect anything , also you can mix diffrenet gpus but it will cost some time to setup and make everything stable to run , as an example for rx470 rig you just install driver for one card then adding any additional rx470 will just be installed automaticaly it is not the case when adding diffrenet gpus models.
