I can't be the only one waiting for 7990s to show up. I feel like they will be the ultimate mining card, probably 1200+ mhash per card, probably cheaper than buying 2 7970s, and should be superior power efficiency as well. All that and potentially great resale value. Best case scenario is nvidia puts some serious pressure on AMD resulting in a low intro price for 7990s.

Anyway, my point is I don't want to invest a lot of money on any other cards right now as long as it looks like we might be getting 7990s in the next few months. If I had to get a card to fill a slot, I'd just grab a cheap 5830.

Have to take into account the looming halving of block-size and the mining exodus that might occur after that if price doesnt adjust fast enough. Might be more profitable to pick up 2x 7970 now if AMD is going to drag their heels till Q3/Q4 to bring the 7990

In conclusion: 5830s are still the biggest bang for the buck. That's the way to go for poor-man's mining (until they remain profitable)

great resale value

i didn't spend $600 on a gtx8800 for its resale value, or $500 on a USRobotics Courier HST, or ...

you dont buy the highest end technology for resell value

exactly why I moved on from them.....simply not enough density possible.

I am with you. It shows there is no perfect GPU they all have advantages and disadvantages. I don't regret going with 5970s. Highest MH/W and awesome density. I couldn't imagine running a 15 GH/s farm using 5830s. Thats what 50 GPUs?

Still everyone's needs are different. If someone is a gamer who wants to mine part-time I would say get a 7970 (or two). Cooler and quieter than 5970 but I wouldn't want to try and build a farm out of them.

i look at them as very nice 'training' gpu's for those (like me) that are getting started with mining. they can be obtained easily, and with a bit of a warranty for short money and aren't really all that bad on power when tweaked for mining. for example, i wanted to test all sorts of things regarding setting up a 'big rig' and certainly wasn't going to run out and drop almost $3k on 5 7970's while not knowing what i'm doing. but for ~$500 in gpu's one can learn everything it takes to build out a large gpu rig including space, power, cooling, adapters, os/software management,.... - without being overly paranoid about damaging something.

I like a mix of 5970s and 5830s. I use the 5830 to load balance the breakers with my 5970 rigs. 1 5970 rig and 1 5830 rig per 20 amp breaker. Puts me right around 16 amps to keep in line with the 80% load rule.

Thats a good plan. I just went the brute force aproach.

two of them for a total of 240*30*2*80% = 11.52 KW (derated)

I'd fight Gandhi.

I have four 5830s running stable at 1000/300 325MH/s. For $100, they are great cards. And can probably sell each one for $50 in the next year or two for the 78xx, or maybe even 88xx series.

uggggg, but they are power hogs.

Anyone has actually verified and can quantify this affirmation?
I have some doubts that they actually consume the same of a 5870.

BTW: I have read somewhere here yesterday that someone has been able to undervolt a Sapphire 5830. I have one, and a Xfx too, and I was not able to undervolt any, both using Trixx and Afterburner. Maybe mines are locked?

I achieve 1.94 MH/w with my HD 5830s. 10 cards, 3 GH/s, 1550w from the wall. They aren't as efficient as my watercooled HD 5970 rigs which are running 2800 MH/s and pulling 1100w from the wall but they are cheaper per MH. I paid $105 per 5830 and they run right around 300 MH/s for 2.86 MH/$. The 5970s were roughly $425 with waterblocks and they run around 700 MH/s, so roughly 1.65 MH/$. This doesn't include the ~$400 in radiators and pumps that cool my 8 5970s.. The beauty of the 5970 rigs though are that once I got them setup they just chug along and I haven't had to worry about them. The 5830s however.. I have two with fans that will likely fail before the summer is out and I'm sure I'll have a few more fans fail that currently sound fine.

5830s will quickly get you MH/s for cheap. You'll pay through the nose in power but they sure do make nice heaters in the winter.

My Sapphire 5830s are some of the coolest and most reliable GPUs in my farm. I have 10 of them running on a pair of 890FX-GD70s and those two rigs have run for about a month now without any intervention necessary. Not the best for MH/w but if I could bulk buy another 10 I'd happily do so.

I managed to push my 5770 to 0.7v, core 920, memory 200 ...for a solid 198Mhz, they might be the most efficient cards out there, but you's really need to cram 6-8 on the same mobo to get the most out of them.

One of the best MH/$ ratios, if not the best..

100 bucks for 300MH is pretty damn nice.

real power hogs.

And a lot of them comes with cheap non ref boards with VRMs that cant handle undervolting either :/

There seems to be a lot of people wanting 5830s in the Marketplace. Was there some new development that I missed or something?

I noticed that people buy certain cards for different reasons. The HD6000 and HD7000 series are for higher resell value or gaming on, while HD5000 are purely for mining. And within these 5000 series cards, is can be broken down even further. There is the initial cost factor, and mining costs factor. The 5870 and 5970 are good when it comes to hash rates per kwh, but their initial investment cost is high. The 5830 has the lowest initial cost investment, but it consumes a lot of power for the hash rate output. This is favorable for someone with low cost or free electricity. It seems that the 5850 is the middle of the two 5870 and 5830 in terms of initial investment and electricity cost.

i'll have to disagree with some of these statements

hd6000 and hd7000 may have a higher resell value, but that's only because their value is higher to begin with. absolute $ is what would matter for our circumstance (maximizing profit from mining bitcoins) and the 5830's have dropped $0 in the last year. i haven't tracked 5870 values until about 3mo ago, but they've dropped about $25 (completed auctions on ebay). the 6000's and 7000's have dropped a lot more. not only in absolute value, but as a %.

expect that to continue, as more recent technology should *almost* always decline in value faster than older stuff.

someone else said they could get 5830's for $60 or something like that, but I don't find that to be the case. you can get them for around $100 shipped easily. you can get them for $80-$90 shipped if you spend a little time at it. the 5850's range from around $115 to $140. the 5870's from around $150 to $200.

i reckon 5830's are still the best buy in retaining value, but they also take up a card slot, same as a 5870 does. so, it'll cost you in terms of space, motherboards, etc. i converted my 5830's to 5870's just recently, since 5870's dropped into the $160-$170 range. in a couple months, 5970's will probably be a buy

you can find some in the hardware section https://bitcointalk.org/index.php?board=75.0 or ebay. don't buy used though, because there's a chance that the cards are in bad shape, which is what happened to this user: https://bitcointalksearch.org/topic/anyone-have-a-5970-with-one-really-hot-vrm-phase-77099
