Some interesting replies on here, with some equally interesting divergences of opinion. My PC is a Dual Core Intel with 8 Gb of Ram, running Windows Ultimate 64-bit. I use Lightroom 4 for importing and tbh I haven't found the setup struggles at all with the D800 NEF files (which I convert to DNG in any case). It's a little slower than with the files from my D700, but not enough to be frustrating. I won't be upgrading any time soon, mainly because a) I don't feel the need to, b) I need to save up and c) I'd have a right faff on to find a better display than the 25.5 screen on my HP Touchscreen without forking out a fortune in addition to a new PC.
So as long as Old Faithful (now 3 years old) continues to handle my D800 files the way it does now, I'm not for upgrading.
My laptop, which is a 64-bit machine, only has 4 Gb of Ram and it handles the D800 files just fine - a bit slower but again, nothing to get my tights in a twist over.
Lightroom 4 and Photoshop CS5 should get the job done.
Hope this helps.
D4, D800, D600
It ain't so much the things we don't know that get us in trouble. It's the things we know that just ain't so.
Why is this thus? What is the reason of this thusness?
