o___O 5870 is kinda.... old.
Easier, yes. Points per dollar, not even close. Boinc doesn't care about extra shaders or memory. The number of CUDA or Stream cores a card has is the only factor. Check this out.
6970 - 1536 cores - ~330k ppd - $300
6950 - 1408 cores - ~260k ppd - $275
6870 - 1120 cores - ~250k ppd - $170
6850 - 960 cores - ~200k ppd - $150
Now the 58xx series
5870 - 1600 cores - ~370k ppd - $150
5850 - 1440 cores - ~275k ppd - $125
5830 - 1120 cores - ~155k ppd - $100
For a dedicated BOINC or Folding rig, the 68xx or 69xx cards are just not worth the cost.
