If you have high electricity rates then don't mine with this rig, all the cards you mentioned above are power hungry and mining isn't profitable at this moment you should buy it and resell for gamers or mine if you have fair or free electricity

I think it is better to buy the nVida cards, they are less power hungery.

yes nice idea to resell after use

I only sell after it is not efficient to mine. Otherwise, I will keep it.

if all the components are is good working condition then the price is a fair one.
you could buy it for resale to the gaming players looking for a mid level gaming box.
and you could make a few bucks

The price is not so good I think, since the video cards are old model and I think it has been used for about 12 month I guess. In general, a video card can mine for about 24 month, if the card are mined more than 12 month, you can use it for about 1 year, and then you will sell it for the second hand.

My suggestion is that I will always buy the latest card to build my rig. Don't buy second hand, unless you know how long time it was used.

Fastest equihash (ZCash and clones) card at this point is the 1080ti - a highly overclocked one might exceed 800 HASH/s but not by a lot.
R9 280x is more like 300-350 hash/sec.

800khash/sec would be a SCRYPT (Litecoin/Doge/etc) hashrate ballpark figure for the R9 280x.

equihash

No, the R9 280 (or 280x, for that matter) will not get 800 kH/s on Equihash.

For perspective, a 2GB HD 7850 can get around 150-160 H/s on Equihash. A 3GB GTX 1060 can get around 280-300 H/s.

I'm not aware of a current single GPU that exceeds 1 kH/s on this algorithm.

i've heard that the r9 280 can go up to 800 khs is that true ?

On which algo?

first of all hi everyone , so i wanted to start mining to change from trading and try something new but being on a low budget 450eur i could'n find a good offer until i came across this offer tell me wht you thing about it : motherboard : 6port PCI express msi Z170 A pro processor celeron

4GB ram module

gpu : 2 R9 280x + 2 AMD Radeon HD 7950 +HD 797

no alimentation nor SSD and all that for 500 USD what do you think ?

Just be careful and check your electric cost. Anything above $.12 will kill alot of your profits. Those 280x/7970 are very power hungry.

yes my bad it's a 7970 and it's 4 card not 5 2 R9 280 and 1 HD 7950 + 1 HD 7970 , and like you said it it' better for the ZEC and that's what i will go for 1250 sol i think is what they can do , and or the power supply can i go with SeaSonic 1200W ATX12V/EPS12V 80 Plus to run everything ? it's 400 W less than the EVGA G2 but cheaper

4 cards should be no issue, presuming that's the Snow Silent Seasonic 1200 watt platinum model (I'm not familier with any other 1200 watt Seasonic model offhand).
I have some of their X-1250 Gold models I've used for years, good supplies, but I don't trust that "fancy name" sleeve bearing thing they put in their newer "Prime" models.
I've also got a BUNCH of their X-850 and a few of the SS-860 models in my 3-card rigs.

yes quite a good price that would get me a 80mhs on ethereum i think

Hard to tell since you didn't list the full model number of the 5'th card (I am presuming it's a 7970 and you just cut off the final zero).

I'd acually guess closer to 70 MH/s on ETH - but the 280x 7950 and 7970 are better at ZEC mining than ETH.

You're going to need a SERIOUSLY beefy power supply, or a PAIR of mid-range supplies to power that beast.
R9 280x from personal experience is a 200-250 watt card on ETH, you can tweak it for somewhat less on ZEC - the HD 7970 is the same GPU as the R9 280x with a bios update and slightly slower ram and it going to eat about the same amount of power, the HD 7950 wasn't a BIG step down from the HD 7950 (equates to the R9 280) so still looking at 150-200 watt ballpark on ETH.

For a single supply running ETH I wouldn't look at anything less than an EVGA G2 1600. The "split" power supply should probably be the pair of R9 280x and the motherboard on a single 850+ watt, and the other 3 GPUs on another one.
Might get away with a 750 for the first PS but definitely NOT on the second one, and you might want to go with a 1000 for the second one.

buy it!

looks like a great price and a pretty decent setup at its cost.

That is quite good price. It is almost $100 for the 280X.

What is an "alimentation" in a computer context?

Alimentation = PSU
