Dear Dr. Watkins! Thank you for the suggestions!
In the local shops I've found only Core i7 with 6 cores (like Core i7-39xx) and 4 cores. Should I obtain much better performance with 6 cores than with 4 cores in case of i7 cpu (assuming that I run simulation in cpu+gpu mode )? Also you've mentioned about 4 PCeI MD. Does it means that modern work-station could have 4 GPU's in one home-like desktop ? According to my current task I suppose that 2 GPU's would be suitable for my simulations (assuming that I use typical ASUS MB and 650 Watt power unit). Have someone tried to use several GPU's on one workstation ? What attributes of MB should be taken into account for best performance on such multi-gpu station ?
