That's old info you're reading.

Get 7950s used, or wait for the new radeons to decide. Mine litecoin or mine at middlecoin.com or multipool.
5870's are actually fairly decent for mining, configured correctly they can yield up to 400KHs in scrypt I've read.

Nope, that's 6950 territory...they were the go to cards for sha256 when people mined 3 btc per day on them.

We use newer cards nowadays, mainly because of scrypt's ram bandwidth requirements and cause of better power efficiency.

hmm ill look at 7950s when i mined litecoin on my 5870s before I was around 300-350 although admittedly I haven't tried recently. any idea what the ROI time on the 7950s is now a days?

and if i go gpu i wont mine bitcoin its just not worth it anymore from what ive seen it would be better to save up $2500 and get a 30-40gh/s asic machine off of ebay

also how are the USB miners not worth it anymore? from what i saw 333 from a $20 usb stick isnt bad they also have some 2.2gh/s 2nd gen usb sticks up for $160 now. Are there just too many asci machines coming online now?

First of all, don't look at buying anything for bitcoin. You'll never pay off your machine with mining anymore, even with the newest machines, or the cheapest USB miners. A 30GH/s miner won't produce $2500 worth of bitcoins ever either.

I'd go with a 7950 if you're looking to buy equipment and mine on multipool. You'd pay off your card in 2-3 months using this method.

@ivan, there are definitely better cards out there now but the 5870's are still great for mining, 5970's as well. A 5870 is pretty close to a 7850 in terms of performance, it does around 40-50KH/s more than a 7850, while only taking about 30W more. And 1GB of VRAM is enough, people are using 7790's and 7850's with 1 GB VRAM and mine with them, no problems.

And compared to a 7950, a 7850 is exactly half performance of a single 7950 (I've found this from testing) and 7950's use around 180-220W I've found as well, so again, I think 5870's are still good mining cards.

So OP, definitely don't get rid of those 5870's, they'll net you around 0.05 BTC per day mining on multipool minus power costs (probably around $2) so you'd be making around $4.50 per day with three of them. That and a new 7950 and you'd pay the 7950 off pretty quickly.

Forget about btc mining, asics I'd buy would be the kncminer ones which have fast delivery and cheaper prices. But sincerely, I'd avoid pre order stuff, or usb asics, or those overpriced ebay ones.
Most of the time you won't get ROI at all with those devices.

You can get ROI with a single 7950 (say you buy it at $180) in exactly 100 days mining nowadays. That without taking power costs in consideration and mining some conservative coin (and no cpu mining).
I mine primecoins on my cpu using beeeeer.org (which makes me 0.2-0.25btc per month) and also mine at middlecoin.com with my 7970 (which makes me 0.4-0.6btc per month).
BTC price can be seen at mtgox or bitstamp (people lately are paying me bitstamp pricing or mtgox -10%)

ya i wont preorder anything kncminer is still on back order as well and damn I would have thought that those $20 USB miners would have had a better ROI especially at $20 or $160 for 2.5gh/s. Whats keeping the ROI down on those devices?

How much luck have you had with middlecoin.com, how long have you bee using them. im assuming the .4-.6 btc monthly is about your average? ive got all the makings to run 3 5870s i may just set it up and try it out

The difficulty changes are keeping their ROI down - it's increasing but about 32% on average every 2 weeks, which is an enormous amount and really cuts earnings quickly.

As for Middlecoin, I can tell you my experience with it. I enjoyed it, except I find their fees a wee bit high. If you set up multipool and cryptsy auto selling the fee is around 1.5%, so you make slightly more. However, Middlecoin sometimes holds your coins until they can sell them at a higher price, which might earn you more in the long run. Also, multipool has more stats but it's honestly personal preference to me.

Yeah, that...auto sell makes middlecoin kinda pointless, except that it helps not kill coins so badly (when not selling in uber low periods).
Gotta be patient with those, it's more of a lazy thing to do, if you don't have time to check it daily.

ya thats what I was thinking with all the BFL asic devices getting into peoples hands now. So basiclly Alt coins are the way to go now it looks like unless you have some serious coin to put down on large ASIC devices

well now the question is do i keep my 5870s or sell and pick up one 7970 or 7950 my 5870s pull between 1000-1100 all together last time i used them to mine

Well why not keep your 5870's and get a 7950? Don't go for a 7970, they're basically just $50 more for like, 60KH/s more, which isn't really worth it IMO.

If you have an extra PCI-E slot definitely just buy a new 7950. If you have all slots full, maybe sell a single 5870 and get a 7950. You have 3 5870's right?
