I'm making the switch and I need some help deciding between a new and a refurb iMac. I do not do a lot of gaming. I plan on using the computer for Internet/Movies/Music/Pictures. The two configurations I am looking at are: New: 2.93GHz Intel Core 2 Duo, 4GB 1066MHz DDR3 SDRAM (can be upgraded to 8GB), 640GB Serial ATA; 7200 rpm NVIDIA GeForce GT 120 256MB GDDR3 (I thought of bumping to the GT 130 or the ATI but I'm not sure I need that kind of power and I'm not sure if I could survive the wait for the ATI) Refurb: 3.06GHz Intel Core 2 Duo 2GB 800MHz DDR2 SDRAM (can be upgraded to 4GB); 500GB Serial ATA; 7200 rpm NVIDIA GeForce 8800 GS with 512MB GDDR3 I need this computer to last me for the next 3-5 years. I think both systems have similar performance but should I go with the new computer as it has more RAM (and greater capacity for RAM upgrade) and HD? Would I be better off with the Refurb Graphics card? I intend on upgrading to Snow Leopard when it is released. Will the RAM speeds make a considerable difference in performance? I really appreciate your help/advice!
