I need the 12 gb of ram. I do a lot panorama stitching in photoshop. When i do it, photoshop tap out my current 6gb of ram.
More RAM the better. I've been dealing heavily with layers. Yesterday, a single image went up past 2GB for me. That's just GIMP. With noiseware open as well, and that machine pulling double-duty, I think the 16GB i have was money well spent too.
The Vishera is OK - but most of the filters and stuff I do appears to still rely on a single thread at times, or doesn't scale very well past 2 threads. The Core i5 is not much more and will be noticeably faster.
Don't know if you bought yet, this thread is approaching a month - but the memory can be cheaper.
corsair 16gb 1600MHz, 10-10-10-27. You don't need the fastest. Diminishing returns here. $104 with 10% off using EMCXTVP43 = $93.60, which saves a good bit and doesn't sacrifice noticeable performance (cas 9 vs 10).http://www.newegg.com/Product/Product.a ... 6820233246
Hope it helps,
