For a 580, I would choose the 3 GB version, but you will get a better BFTB with a 570 card. The performance difference is marginal, the price difference sizable.
As always, Harm, thanks!
BTW, I'll be running the PPBM5 this weekend on a build I don't see in your list (maybe because it's no good?). It's a dual AMD Opteron 6272 (32 total cores) and 64GB ram. I built it more as a render machine for Cinema 4D and After Effects, but I'm curious how it would fair with Premiere. All the Opterons I see on there are buried deep below the Intels. Hope I can change that with this rig.
Looking forward to your results.
Yes, there are only 2 AMD 16 core (32 with HT) systems in the results, one a dual Opteron 6128 and the other one a dual Opteron 6134 but both with far less memory.
Yea, not a good showing for AMD.
These AMD 6272s are true 16-cores each (no HT). So we'll see how it goes. I've got two 6128s in there right now (8-cores each) and it bearly keeps up with my i7 980x 4.2 GHz. That's when I ordered the 6272s to replace them.
I'll let you know. We'll both find out soon.
The basic problem with the AMD chips is the lack of SSE-4.1 and SSE-4.2 instructions which are key to great performance with Premere Pro. I though "bulldozer" was supposed to correct this but it does not look like it happened.
Also if you do not have to jump on the GPU purchase there are rumors that nVidia is about to introduce the next generation graphics cards sometime this month, it may or may not happen but at least you should be aware of it, it may reduce the current GTX 500 series prices.
Thanks for the heads up, Bill.
