One of these will be my new mining mules for the summer, both reselling prices with sufficient warranty, and won't lose much of their price for a few months. Should I wait a bit more time (2 weeks) and pay more for the HD6970 or start using the HD6870 right away? I'm limiting myself to a single GPU, which coincidentally will double as an actual gaming video card for a few hours everyday.

6970-ul e mult mai bun pentru minerit decat 6870-ul, iar diferenta de pret intre ele e relativ mica. O recomand pe prima. Sau si mai bine, vezi daca gasesti mai ieftin un 6950 de referinta, ii poti da unlock la shadere si il transformi intr-un 6970 practic. Daca ai noroc poti scoate spre 400 MH/s cu el. Eu cu trei din alea scot peste 1,1 GH/s.

...Oh, and in case speaking in tongues on the forum is restricted or smthng, I was just telling Killer Bomb here he'd be better off investing than mining, buying hardware is a surefire way of getting hit by lightning when setting up your box.

Hello,

i would prefer a Graphic card out of the HD58XX Series for mining. The architecture of the 5000-series is more opitimized for the sort of parallel computing which is needed for mining. And it's also cheaper.
The best MHash/sec per Cost value has, in my honest opinion the 5830, followed by the 5850 and the 5870. I was lucky getting a nearly new 5870 für about 120EUR today at my local dealer. So if you want to have a dedicated mining System: Choose the 5830 perhaps two oder three of them. If you want to game also, then youn would be better off with the 5870 (for the purpose of mining - due to the architectural properties of the 69XX series, these are better optimized for gaming benchmarks, than for parallel computing.

 


If you like my advise, i would be thankful getting a small donation at:

+33% Mhash/s, +33% EUR Smiley

Mersi de sfat. HD 6950 e la 220 EUR, si scoate mai bine ca 6970....

Points taken. The 5850/5870 were on my list, but keep in mind I want to buy or have a single GPU in the system, otherwise I would go into power issues/costs, cooling issues/costs and performance fragmentation. So I'm trying to get the single best board available, might upgrade again later this year if this goes well, if not, I have some gaming catch-up to do...

I had the 6870 and the 6970 as very optimal cards for Mhash/s and Mhash/J, and these are deals from friends (include 1+ years of warranty on them). I will look into the higher 5870's at around 230 EUR too...

The performance of the 6870 isn't great.  I only get 260MH with mine, and the 5850 I just picked up gets 290.
