So here's the deal. I've got a maxed out MacBook Pro 15" mid 2010. By maxed out I mean, High-Res AG 2.8 i7 8Gb Ram 120 SSD ... I'm sure you know the rest Ram and SSD are upgrades from OWC. Needless to say that it is pretty fast. Geekbench gives consistent scores 5900-6000. So the most anticipated upgrade to the new line of Pro's is the inclusion of Sandy Bridge chips. From what I understand this would mean a boost in processing power and better GPU. But I have no idea of the specifics. For example what would be an anticipated benchmark score? Just an estimate. Reason I'm asking is because if the expected increase in power is in the 10-20% range I don't see a me selling my current Pro to get the new one. If it's expected to be more I'd consider it. One would recommend waiting for the new line to be released and then decide what to do. However, I am afraid I will loose much of the resale value if I decide to sell after the introduction of the new Pros. Lastly, would I be able to use my current 8Gb Ram with the new line? I mean, does the introduction of Sandy Bridge mean new Ram specs? I know there's much speculation going on here but any thoughts will be greatly appreciated. Thanks!
