I do a lot of heavy Photoshop work. Coming from an early 08 MP with 12g ram, a 512 nvidia gpu, and no ssd, would the "new" MP be a substantial upgrade? Also, it looks like their 512 ssd dropped in price. Is it worth the cost now? I haven't seen any other sites that sell one that large. Edit: aside from the ssd, I'd also be looking to increase the ram to at least 32g from a 3rd party retailer.
