Is the new 3.06 Ghz (with the GT 130 in it) a "downgrade" compared to the one I bought last week ( 3.06 Ghz with the 8800 GS)? I thought I knew what I was going to do, take this one back, for the newer model. But after reading so many posts on this and other sites, I'm starting to think the new 3 Ghz iMac is inferior to the one I currently have (have 4 GB of RAM in it already but the RAM I put in can still be returned for full refund ). Unless you factor in the 4850 GPU but that is a non-comparison since right now I could only return this one for the GT130 machine. Wouldn't returning my current week old model for the new one with a bigger HDD and DDR3 (and more of it) and the GT130 make sense for an even swap (if my friendly apple store is nice and doesn't make me eat 10% RSF)? Hard drives have never played a factor in any of my computer purchases or builds for what it's worth. So really the only up side I see is the 1066mhz RAM vs my current 800 DDR2. But I think the new model actually use a lower end processor than my current model and then there is the great 8800GS vs GT130 debate. It's enough to make a pretty laid back guy go crazy! In short, I'm hoping you guys/gals will go "Clash" on me and come right out and tell me what you think - should I stay or should I go?
