I get 265H/s from stock R9 280 3gb (core 940) using ZecMiner64 @ intensity 5

Me too. All my 280x get 180hash on 6 card rigs. BY FAR the best zcash gpu. I dont think others can compete for the price.
The 280X is about 200H for the Claymore miner. That is quite good performance considering it is more than 4 years old.

My 280x's get just under 180sol/s on all Stock Settings and Stock Bios with Intensity set to 2, 175sol/s on average.
very intersting, which model 280x?Gigabyte Windforce and a Sapphire though the Sapphire runs a fair amount cooler.

that is very good. If you have cheap electricity and the 280X price is very low, you might get some ROI.

Well I went with a 2nd hand 280x instead for only $10 more than the cost of the 280, so now I have 2x 280x 
Both on stock bios and stock clock settings with AMD 15.12 Drivers I am getting from 168-180 sol/s on average with intensity set at -i 2 on the both of them.
I tried -i4 and it was a bit more powerful but after a little bit 1 GPU dropped off in hashing after a while to just over 110 sol/s until I gave it a 1 minute break and restart, I also tried -i 0 but only got 140-150 sol/s
Even at intensity -i 2 I still get the occasional drop in hashpower on the same GPU that requires restarting of the miner and then things go back to normal which is weird.
350 sol/s from 2x 280x I am happy with, now I just need to test how many Watts it draws when mining.

it's use full i use a R9280 not X version and it gets a little less then the X version does so yea it's good for Zec mining not much else it should get close to 161 Sol or higher, the x version according to others does a little more but you have to use claymore miner till Silent army matches speeds and they will and are working on it now . listen to the others also about Electricity it may eat up a lot power but if your in it for fun and don't care ROI it very use full for ZEC mining.
IM at stock setting boost is off
ZEC - Total Speed: 161.217 H/s, Total Shares: 2065, Rejected: 1, Time: 03:54
ZEC: GPU0 161.217 H/s
with boost on it went lower , i even set the memory to 1500 didn't change a thing and max the clock to 1100 speed stayed the same the only thing i didn't do yet was mode the bios.

That is a good hash rate for zec or zcl. Only problem with the 280/x is they use a lot of power, so your electricity price will be a big factor

Nothing ? No Answers at all... ? haha I guess a lot of people don't mine on these kind of AMD rigs 
All joking aside my 280x hits 180+ sol/s on Stock Bios, Stock Core Clock/Memory Clock & Default miner Intensity when mining with the Equihash Algorithm.
So you should see a little under that to sum it up in basic terms.

Hello all,
Just a question, would a AMD R9 280 GPU be decent for mining ZCash & Zclassic ?
I already have an AMD R9 280x and it is making fairly good hashrate with stock bios at 120+H/s at -i 4 Intensity
What could I expect from the 280 ? Close to if not the same Hashrate ?
I am considering buying a 2nd hand one and the specs are as follows:
Gigabyte Windforce OC Version PCI-E 3.0 REV 1.0
Radeon 3072MB GDDR5/384 bit
950MHz Base Clock
1175MHz Boost Clock
What are your opinions ?
