I just recently bought an PE4H-EC060A module V3.2 and paired it with Gigabyte GTX 660 and it's working great. Plugged it in, installed drivers and voilà. X220, i5-2520M, 8GB, SSD ~18500p in 3dmark06 http://www.3dmark.com/3dm06/17572649 ~5200p in 3dmark11 http://www.3dmark.com/3dm11/8208499 But has someone tried a Quadro K2000 (or K600) setup? I bought the GTX660 on the assumption that it beats K600 in specviewperf 12 (based on a test - SPECviewperf® 12 - GPU Scores | PC foo), but I can't even come close to those numbers. The K2000 and GTX650 are both GK107, is there a chance of "error 12"?
