I am planning to buy a second GTX 1070 (Gigabyte G1 Gaming) for my computer and was wondering what configuration to set it as. Ignoring the fact that a 1080ti is better that 2 1070s in SLI, should I put the new card as the primary card or the old one. Common sense would choose the new one as primary as its just, well, NEW. So I was wondering if this is the right way to do it?
