I've recently bought a used GTX970 (Gainward) to replace my aging AMD HD7870.
When I installed it in my system, I was shocked to find performance was almost the same, rather than approx. double that of the old card.
I ran a benchmark (Passmark PerformanceTest "3D Mark"), where the GTX970 in my system came up at only ~5900 points, rather than the average ~8800). The HD7870 achieved ~4700, slighty above average for the model, which led me to assume I wasn't bottlenecking.
On another system, the GTX970 ran perfectly fine, with the same drivers and a similarly clean installation of Windows 10, achieving ~9100 points - I'm now searching for the bottleneck that's keeping my system down with the GTX970.
Specs of my system:
Mainboard: Asus M5A97 R2.0, newest BIOS
CPU: AMD FX-6300
RAM: DDR3 1x4GB, 2x2GB Dual Channel at 1066 Mhz (<- Bottleneck?)
PSU: 550W
Specs of the well-running system:
Mainboard: MSI B350
CPU: AMD Ryzen 3-2200G
RAM: DDR4 1x8GB "DDR4-3000"
PSU: 500W
Could it really be garbage RAM slowing down the Graphics benchmark so much?
