Actually I ordered it with 12GB of RAM. It seems to be just fine - Photoshop is using 6.58 GB (60%) of the available 10.966 GB of RAM. Once Photoshop is open (that takes about 15 seconds) and I close it and then re-open it, it takes less than 1.5 seconds to open. To me that's fast.
BTW, the two exterior HD's are recognized - as you said they would be - without any isssues.
It takes about a minute from pressing the power button on the computer to be fully open. I know an SSD with the OS in it would speed that up but I honestly don't care about the intialization of Windows - one minute is fast enough for me. What I DO care about, and what I've found remarkable, is that Photomerge (the pano program within Photoshop) now does its work in less than two minutes! Sometimes less than 90 seconds! That's blazing speed to me. I'm a happy camper.
Again, thanks to you mibix19 for you quick response.
