rec. for SU:
• CPU : intel Core i7-4790K/i7-6700K
• GPU : nVidia GeForce GTX 960/970/980 (slower <-> faster)
• RAM: 16 GB (2x 8 GB)
• SSD : Samsung 850 Pro (at least as system disk)
not: AMD CPUs (slow) / GPUs (bad OGL)
not: integrated/shared video systems as intel HD series (bad OGL)
not: CAD video cards as nVidia Quadro or AMD FirePro (no advantage; expensive)
