7950s, hands down.

7950s, hands down.

At what price and model?

7770s' cost $80 with the sale of the crap game = 170ish M/hash  2.125 M/Hash per $1
7950s' cost $270 with the sale of game = 580ish M/hash  2.148 M/hash per $1

BUT PSUs' have dramatic price jumps over 1000 watts. So I believe mixing the 2 cards is best. Also mixing them allows for more rebates to be valid. Also in theory selling them is easier since its targets multiple markets

7770s are the most bang/$ but they're horrible for density.  7970s are probably the best for density (7990s suck for now it seems)

[crazyates]

If you wanna buy a 7770 and a 7950, that's fine. 7950s are not that far off for the the best bang-for-buck, and they're also not far off from the density of those 7970s, so there's a reason you see all kinds of people building 4x 7950 rigs, for both BTC and LTC.

Simran loves his 7770s

5770s mine 90% as fast as 7770s and you can find them used for < $50...

Yes but for $10 more after selling the game code a 7770 with a warranty and lower energy usage is a better deal.

The 7xxx series cards are good because of their lower power consumption. I use 7950s and 7970s. Probably the biggest disadvantage to the 7970 is the higher cost for the PSU if you're putting together a high density (4+ GPU) mining rig. Also, if you're on residential power, you have to be creative in not overloading your household circuits. Been there, done that.

It's always been been the Ati 5830. (2.9MH/$)

260Mh/s for about £60/$90 (some people even claim to run them at 300Mh/s)

That's 1Gh/s for <£240/ $360

I would not recommend any 5xxx cards. It's not 2011 anymore. They're old, which means their expected lifetime is coming to a close. They're also draw a lot more power, which can make a significant difference.

A 7850 pulls more MH/s than a 5830, and uses about 2/3 the power. Plus, 7xxx cards aren't 2-3 years old, and many of them have warranties!

[Gator-hex]

The 7850 are nice cards, I use them too, but I can have 2x 5830's for the same money which is an extra 220MH/s (300MH/s vs. 520MH/s). *

*no volt overclocks.

5830 is perhaps the most power-inefficient 5xxx series. The 5850 and 5870 are quite efficient with proper voltage settings (as are 57xx cards).

Still, warranties and free games make 7xxx more desirable.

The 7790's are better deals.  I love my dual ASUS HD7790 cards.  They are less than $130 each after selling the game codes.  I overclocked them to 1190Mhz (stock 1075) at stock voltage and they run cool (62°C) with an ambient temp of 78°F (I am in So Cal).  They mine bitcoin at 290Mh/sec.  That's almost as fast as my old 6870 cards at half the power usage and runs much cooler.

6950.  You can get a visiontek 6950 here for 169.99 when they are in stock: http://www.tigerdirect.com/applications/searchtools/item-details.asp?EdpNo=7581172&Sku=V261-6954&csid=ITD&recordsPerPage=10&body=REVIEWS#CustomerReviewsBlock

I have mine running at 450 kh/s each.  Thats 2.647khps/$

[ecliptic]

I'm amazed the games are worth anything.

U get a free video card with the game so they are worth it

i have had good experience with the 7870 tahiti core cards, 500+ mh/s, low wat usage too.

keep in mind tahiti, not normal 7870.

Is Sapphire PowerColor the only company that sells the Tahiti version?
