What is the best GPU card to mine scrypt algo?

[buddynuno]

Hello everyone,

I have looked at https://litecoin.info/Mining_hardware_comparison

But I am looking for the opinion from the miner's experience to know what is the best GPU card to mine scrypt algorithm based coins considering the following:

-Which is the best series: 5*** 6*** 7*** R9 2**
-KH/s
-Stability
-Wattage when OC
-Performance if Crossfire
-Performance on mining rigs
-Price
-Other important info you might want to add

Thank you all for the help

imho by this order, but the current prices cause distortions:
7950
280x
7970
Some 270x or 270 with GDD5 5600+
R9-290 with custom cooler.
7990
Some 7870 and 270
R9-290 with stock cooler
6950
6970
5850 and 5870
6990
5970

The R9-290 are in the middle because afaik they cannot be volt modded with VBE7 or other utility. If I'm wrong, then they climb up to near the 280x

That said, the last ones can sometimes be the best if you get them for the right prices.
For example, it's ok to buy an used 7950 at $200, while it becomes silly at $300 or even less

I had a bad experience with 2 6950's in Crossfire, but that was some time ago

I have the chance to get some cheap 7850's. Is it worth buying them? I would have to buy everything else as well, even mobo.

Depends on how cheap and how many. If they are 120€ or less, then I'd go for them. If possible, test one beforehand, because "cheap" may mean unstable or stressed out.
