Nice, that's a significant improvement.
Well, I got rid of this card. Returned it to the original seller, and bought a GTX1080 that came up for sale.
I think I was having driver issues. Games would freeze randomly, and Windows was acting funny at times (non responsive after waking up from S3 sleep state). I've read things about AMD drivers, and maybe it just got in my head. I'm not sure if the GTX1080 will be faster or slower than this card - I've seen different benchmarks showing both. I figure it'll be about a wash, if anything, a little slower. The biggest advantage here will be Nvidia drivers and their polish.
