Best mining card for under $100?

[davidian22]

Hi,

I would like to know what the best mining gpu is for under $100. Any links to buy it would be appreciated!

This may or may not help you. But scroll to popular mining cards, and look at hash rate and price. There's some pretty good info on there. Hope I helped!

Yeah I already was there. But I cant find any of those cards. I was looking for the amd 5850 but all i can find is Sapphire.

XFX HD-677X-ZAF4 Radeon HD 6770 1GB 128-bit DDR3 PCI Express 2.1 x16 CrossFireX Support Video Card

...should get around 200MH for $100

Your not going to get much hashing power under $100. You should consider investing more, buying dedicated hardware such as ASICS, or just buy BTC. HD 5870'S go for about $160 on ebay. A 5870 should get you 393-420 MH/s which would make you about 3 bitcents or $3.83 every 24 hours (at the time of writing this). Hope this helps!

Ati 5830 (£60/$90 on ebay) 260-300MH/s depending how far you overclock.

Obviously with the recent interest in Bitcoin these cards will be in short supply right now.

5830's are going to be the best if you can find them, i bought 2 about a year ago and they do about 280Mhash each.. so best cheap card.. but they're so rare now.

better off not buying any cards, and buying asics

[bahehs]

Ati 7850 is a great card to get.

Double the price and not much faster at mining.

AMD produces the chips and reference designs, and companies like Sapphire, XFX and others make the actual cards you can buy.

But if you're thinking of buying a GPU strictly for mining purposes you better work out the math first. It may take you a long time to get your money back. Also keep in mind that the difficulty is likely to increase quite a bit now that ASICs are getting deployed.

My 0.0000001 BTC on eBay, with the recent changes to their site, make sure you scroll down the left and select world wide after each search!
that one button auto moving to local after each search is a pain and has hid alot of hidden cheap things since it started.

most ( not all ) 512MB cards are the ' intro ' to Open CL ( mining rigs ) so that is a good place to start.  Just avoid any Nvidia 8600 ( any kind ) as there is an issue on the solder paste on them making them a ' bake every few months ' to get back to working. I have one and have spent a week trying to get it up and running again and ran in to the issue that Palit just plain ignores they are the ones that produced it in the first place.

What are the differences between XFX and sapphire cards?

David

[c789]

From my limited experience, and from reading posts here, it seems like Sapphire are better quality and have a little higher hash rate - and they're more expensive.

I have XFX and Sapphire cards and the Sapphire gets about a 15% better hash rate. But, there are so many variables that go into hash rates (cgminer settings, etc.), so your results may vary. I'm still happy with my XFX though...it does the job.

[Gurthang]

Sapphire are generally cheaper too.  Check out Directron's prices.  They generally beat NewEgg.

Anyone find one that can be had for BTC and TRUSTWORTHY
So far, all that I can find would reqire a 3rd party to ensure the card was sent
