      I opted for a GTX660 (see post #1 in this thread) and now it is installed on a x79 mainboard with i7-3820 CPU. Result: 3 BRP4cuda32nv301 tasks simultaneously take approx. 3100 s < 52 min. This is a factor 1.85 increase of performance compared to my old GTS450 and power consumption is only slightly higher than before.
