It's Black Friday. What matters most?
The Sapphire 470/480 OC cards are the best. Why should I buy 8 GB vs. 4 GB when my current 470 OC 8GB is utilizing 2300 MB, according to GPU-Z, and mining at 180 H/s? 4 GB should do the same?
My gut says go cheap and beautiful 4 GB cards to complete my 7 GPU rig. Why not?
