Get the one that's going to be easier to expand & upgrade as it gets older.

I am thinking of buying a new 27" iMac, one of the standard configurations (so I can get a discount this weekend). I'm looking at the base and middle option. The differences are: AMD M380 vs. M390 graphics 1 TB 7200 RPM HD vs. 1 TB fusion drive $200 Photo editing (lightroom) is probably the heaviest lifting the machine will do. I know that Lr can use the GPU but I haven't been able to find much information about the difference between the M380 and M390. Now that the SSD component of the fusion drive is only 24 GB I'm not sure how much of an advantage that is over the straight HD. If I get the straight HD I will almost certainly use an external Thunderbolt SSD for most things, and use the internal drive for photo + music libraries. If I get the fusion drive, maybe that will be fast enough on its own, I'm not sure. If it's not and I still end up with the external SSD boot drive, I'm wondering if the fusion drive will actually be worse for photo and music libraries since it is presumably a 5400 RPM drive. (I guess, for the price of the middle M390 + 1 TB fusion drive model + external Thunderbolt SSD, I could get the top standard configuration with M395 + 2 TB fusion drive + slightly faster processor. The 2 TB fusion drive has 128 GB of flash. I'm just not sure how that would perform compared to an SSD boot drive). Thanks for any advice.
