 +<ArtForz> I mean, 6970 is pretty exactly as fast as 5870 for me
 +<retsilex> ArtForz: 6950 .. would you recommend it?  instead of 5870
 +<ArtForz> well... for 3D, yes, for mining.. no
 +<Diablo-D3> retsilex: 6xxx is useless for mining
 +<ArtForz> you need sdk2.3 for 69xx, which has broken OpenCL multigpu support
 +<Diablo-D3> retsilex: you're stuck with sdk 2.2 or 2.3, which is shit
 +<ArtForz> so unless you have a CAL miner, 69xx sucks ...
 +<Diablo-D3> retsilex: 6970 should be 15% faster than 5870
 +<Diablo-D3> but its not
 +<Diablo-D3> because the sdk fucks you over
 +<retsilex> ArtForz: your desktop uses which sdk, which drier version? and what linux?
 +<ArtForz> debian sid, 2.6.32, fglrx 10.9, sdk 2.1

 +<foucist> ArtForz: i heard you were the guy to ask about the reason for the drop in stream processors between 5970 and the cards that come after :P
 +<ArtForz> foucist: pretyt simple really, 5xxx had pretty bad shader ALU use % in games on average
 +<ArtForz> so 6xxx got more fixed-function ahdrware, beefed up frontends, better mem controller, ... but shader ALU * MHz went down
