Hi everyone, this technical question goes for experts who are sure about the information that they will give. the question goes, when you increase the number of GPUs on your one motherboard, does the HASHING SPEED multiplies or does it add up ?? Example: suppose the hashing speed for GPU of Radion 5830 is 300 Mhash/sec, when you add another 2 GPUs, what would be the total speed ? is it A. 300+300+300=900 or B. 300*2*2=1200
