OS: Win 7 Pro 64Bit [ver 6.1.7601]
Miner: Nicehash Miner v.: 2.0.3.0

CPU: Intel i5-4670K 3.4GHz
GPU1: Asus GT640
GPU2: Asus GTX770

I'm trying to get my windows rig to mine using one or both of my GPU's ... One is an older one, ASUS GT640 2Gb Low Profile from my SETI Linux Rigs I made, and the other is a GTX770, a very expensive card I bought a while back. I've got some GTX750ti LP as well, haven't tested those yet, but I don't want to use those, because I using those in my Linux rigs which I hope to get to work using Linux. But, this win rig here, I've heard that you can mine using nicehash even if your GPU isn't from yesterday. And this is why I'm trying ethereum.

Running the benchmark shows both cards, but only the CPU is chosen when running the miner. I've been trying for 3-4 weeks now. I'm not just asking away here Please help me

Kind Regards,
Dan
