Yeah its pretty beefy, I've got a Corsair 600t, decided to spend the money on a decent sized case a few years ago so will fit easily enough.
trying to find any stats on what sort of fps benefit this situation would give though, struggling to find anything. Most videos / stats that i've seen is people pairing up very old 400 or less series cards with a 580 or 600 series. I'd have thought the 570 phantom is a pretty decent card to pair up with a asus 970.
Would I disable the 570 in Nvidia settings when i'm not going to make use it of and enable it when i do? or would it sit there not consuming any power until its actually needed?
Any rough stats? or resources to look up potential benefits? Generally speaking, I play Battlefield 4, Shadow of Mordor when it launches in a couple days.
