Currently best GPU for mining

[HighSociety]

Hi all I would like to get my lovely behind into mining. And was wondering which card / setup is the best out there at the moment?

For bitcoin, i wouldn't bother with GPU mining - better to grab some USB erupters if you're starting out .

Sorry it won't be for bitcoin haha but alternative cryptocurrency. I've heard some good stories about the R9 290 ?

ah gotcha. 7950 is the best I think in terms of power/performance. 290 i don't think is worth it over a 280, but the R9 cards are just a refresh of the 7xxx series cards.

this will probably help you:

I'm using several of the R9 280X cards. Though they are hard to find now. Have a look here for a comparison: https://litecoin.info/Mining_hardware_comparison

I can only get 820Kh/s from mine, its the Sapphire R9 290. Would you be willing to share your cgminer settings?

Not at all, I've two main boards Z87 Pro, each have 2   R9 280x cards. I'm waiting for powered risers to add more cards. I've a 1200 watt PSU on each, so I'm not expecting problems upto 4 cards. The board has 6 PCIe slots.

Currently I'm getting 750-760 khs out each of these cards with the following settings in guiminder-scrypt using CGMiner

--gpu-platform 1 -d 0 -w 256 -v 1 -I 13 -g 2 -l 1 -T --lookup-gap 2 --gpu-powertune -20,-20 --auto-fan --temp-target 65,65 --temp-overheat 85,85 --temp-cutoff 90,90 --gpu-memclock 1500,1500 --gpu-engine 1080,1080 --expiry 1 --scan-time 1 --queue 0 --no-submit-stale --thread-concurrency 11200
