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) Smiley

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 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.

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

2 steps down

Dacentec, best deals for US dedicated servers. They regularly restock $20-$25 Opterons with 8-16GB RAM & 2x1-2TB HDD's (ofc, usually lots of other good stuff to choose from).  I did a Serverbear benchmark of one of my $20/mo Opteron (June last year), it's here.  Have had about a half dozen different servers with Dacentec, & none have failed to sustain at least 40MB/s (burst higher). My favorite is a 12-month rent-to-own ZT Systems 2XL5520 16GB 2x2TB SATA for $40/month (got lucky with the 'off-brand', haven't seen a RTO 2xL5520 for under $50/mo since -- at least for monthly contracts).  wholesaleinternet.com has some ancient 2-core intel CPUs @ $10/mo sometimes (I got an Intel Core 2 6300 @ 1.86GHz, with a 250GB HDD with 46000 hours on it, LOL. $20 @ Dacentec is much better, if you can grab one). joesdatacenter.com (same location as Wholesale Internet) also occasionally has specials (or if you don't want to wait, it has an AMD Opteron 170 @ $16/mo).

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)

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 Smiley
