The fastest of the desirable retail MacBook Pro 17" machines. 16 GB system memory (RAM) 1TB SSD (Solid-state drive) Quad-Core i7 2.4 CPU, that TurboBoosts to 3.5GHz If you are reading this ad, you already know why this machine is priced where it is. I am pricing it at less than I would get by selling on e Bay (recently one went for $2,500), but it saves me the fees and shipping time. Thanks.
