Howdy, all. I'm going to buy an aluminum iMac very soon and from everything I've been extensively reading, I think I'm right in this assumption but I just wanted to confirm: A 2008-model iMac 3.06, if maxed out with 6GB RAM should be comparable to the 2009-model iMac 3.06 with its standard 4GB RAM, since the graphics cards are pretty darn close.... right? I know the hard drive size will differ, unless I were to open it up and upgrade someday. I can get the '08 model at bhphotovideo.com for $1549, upgrade the memory for about $160, so it's just a bit over $1700 (another hundred for a 1TB upgrade, which then leaves me with an extra 500GB to put in an enclosure) ..... or I can pay $1849 for a refurbished '09 model with the works. Either way, the '08 model maxed out will cost me a little less, once I factor in sales tax to Apple. So I think I solved my own problem. So now I'm wondering: Do I really need to max out the RAM to 6GB or will 4 suffice? I know it's DDR2 vs DDR3 and the difference doesn't seem to be dramatic. Advice? Oh yeah, I use my computer mostly for print and web design but want to get into video in a few months, hence the desire to have max specs.
