Yesterday I was working on a big photography comparison involving many 16-bit layers from 18/22 megapixel cameras, also scaled up even larger.
Here’s why I need that 80GB, and I would prefer 96GB— Photoshop CS6 was using a whopping 56GB of real memory! The only way to avoid very sluggish performance is to make sure that such big jobs stay in memory!
And here’s why I insist on a RAID-0 stripe of OWC Mercury Accelsior PCIe SSD cards (though Photoshop has internal bottlenecks that limit its speed):
A single Accelsior PCIe SSD is just fine, but because I often have really big files (save size of 4GB - 24GB), I opted for the dual-card RAID-0 stripe.
CS6 performance prefs
Due to a performance bug in CS6, a scratch volume still gets used at inexplicable times, so I use Scratch, my RAID-0 stripe of dual OWC Mercury Accelsior PCIe SSDs.
I never use the GPU (“Use Graphics Processor”); it causes visual glitches, and is actually slower for common operations.

I just love stuff like your Photoshop Preferences and your Mountain Lion Advice.
I thought something was the matter with my new 5770 card,( graphic glitches), until I read your piece, and of course you were right. I also adjusted the memory down from 95% to 75%(32 gigs).
Don't find that kind of thing anywhere else on the whole net that I know of.
Everyone else:(the usual Mac fanboi sites), are touting how cool the latest cat is for one stupid reason or another far removed from any professional needs.
DIGLLOYD: I can’t see anything beneficial to professionals yet in OS X Mountain Lion except removal of a few things that now slow my work down. But I did get back “Save As” with an obscure command-key shortcut.
