Second choice of course

1) The more machines you have, the better it is because the data is spread on all of them and you'll benefit from parallel processing

2) CPU for the second choice is almost as powerful as the first choice

3) 16Gb of RAM is OK if you have SSD. Usually the bottleneck is the disk I/O
