GeForce GTX 970 (4095MB) driver: 362.00 OpenCL: 1.2 i3-2130 CPU @ 3.40GHz Windows 10 = 1,072.02 Run time

GeForce GTX 980 (4095MB) driver: 362.00 OpenCL: 1.2 Pentium(R) CPU G3258 @ 3.20GHz Windows 10 = 769.77

GeForce GTX 960 (2048MB) driver: 362.00 OpenCL: 1.2 i5-4670K CPU @ 3.40GHz Windows 7 = 1,790.06

GeForce GTX 750 Ti (2048MB) driver: 362.00 OpenCL: 1.2 AMD FX(tm)-8320 Eight-Core Windows 10 = 3,367.13

I definitely need to upgrade my GPU's. Here's the run times on my Radeon HD 5870's... and thus my problem with fixed credits on Amicable Numbers.

I tried a 5970 on it, but it was obvious it was way to slow. AN seems to have a preference for NV. Tahiti's are not terrible, but not as good as the NVs.

Edit: Though the Tahiti's are slower than newer NV's, they are a big improvement over the cpu version.
