You could also buy a refurbished mac. They tend to be about $300 cheaper than the retail version and tend not to have any problems. I just bought one and so far its been perfect.
I just bought a MBP 15-inch retina display with a 2.3GHz i7, 8 gigs of 1600MHz DDR3L SDRAM, 256GB Flash Storage, and a NVIDIA GeForce GT 650M with 1GB of GDDR5 memory. What about that is outdated?
