So this is my situation, just bought a pre-owned mac pro 2009 from eBay( already sounds like a beginning of a tragedy). 3.46 12 core 128 ram with pcie ssd and titan x. On the item description there's a geek bench screenshot that shows 31000+ on august 2015. And when I received the mac today, just a year and a half, ran the geek bench, it becomes 18000+. SO! Is that possible that using a mac for a year and a half can lead to this kind of drop? Or I definitely ggot a lemon? Will post the screenshots later, just couldn't sleep thinking I might be f**ked.
