Newegg via eBay offers the AMD FX-8350 Black Edition Vishera 8-Core 4GHz Socket AM3+ Processor, model no. FD8350FRHKBOX, for $159.99 with free shipping. That's tied with last week's mention and the lowest total price we could find by $20. It features an 8MB L2 cache and 8MB L3 cache.

Update: Newegg direct now has it for the same price via coupon code "74JULY157", and Amazon also charges the same.
