I can finally afford to build a computer that can really deal with the graphics that Railworks can deliver. The core computer is a Asus M series desktop AS M51AC, CPU CI7 3.4, Memory DDR3 1600 @ 16GB, HDD 2TB SATA3. Video Card is a NV GT625/ 2GD3, Adding 750 watt power supply, and a GTX780 SUPERCLOCKED (EVGA - NVIDIA GeForce GTX 780 SC 3GB GDDR5 PCI Express 3.0 Graphics Card). Ok but I am waiting on the parts but paid for and ordered. So for the time being I hooked up my new Samsung monitor VIA, HDMI and wow, just the replacement of the monitor made the difference. I had asked about this and I was told that monitor technology does make a big difference in performance.
