i recently bought an early 2009 model for a good price. It has the 2.66 cpu, 8gb ram (4x2), 640gb hd, GeForce GT 120. I was thinking of buying some ram, maybe 16gb. Also a more modern Nvidia card. Possibly a 256gb ssd. It seems that would make it passable for what I do : World of Warcraft, web, light video, music, animation. I figure the upgrades would cost me about $400. Keep it, upgrade it, sell it or gut it? Thoughts?
