I think gnarly1 is trolling, the water pump speed does not increase FPS. I use the website PCPartPicker to assemble a parts list when building a machine. I would recommend looking at the sample builds for ideas, their forum also has a section where you can post your requirements,budget, etc and other users can post a suggested parts list.

The first number(s) represent the graphics card generation, 9, 10, 20 30 etc. The last two numbers (roughly) represent the relative performance of each card within that generation 30, 50, 60, 70 80, 90 etc. The higher numbered cards are more powerful. NVIDIA also uses a Ti or Super suffix for some models that are more powerful than the base model, e.g. the 3070 Ti sits between the 3070 and 3080 in terms of performance. To answer your second question, the 1070 is more powerful than the 980, but the 1050 is weaker than the 960. https://gpu.userbenchmark.com/Compare/Nvidia-GTX-980-vs-Nvidia-GTX-1070/2576vs3609 https://gpu.userbenchmark.com/Compare/Nvidia-GTX-960-vs-Nvidia-GTX-1050/3165vs3650

What tool are you using to edit DDS files? It sounds like it may not support some of the newer DDS formats. Regarding Windows Explorer thumbnails, Microsoft's built-in DDS reader only supports the DirectX 9 formats: BC1 (DXT1), BC2 (DXT3) and BC3 (DXT5). Windows Explorer will show thumbnails for BC7 DDS files if you install Paint.NET and set it as the default program for opening DDS files, it takes over the DDS thumbnail rendering from the OS.
