I could need your help. I got a refursbished workstation as a present. Its GPU is too old to enable GPU acceleration. It'd be great if someone could point me towards a newer yet affordable GPU!
Thank you for asking about the amount of RAM on the GTX 1660 Super. All 1660's have 6 GB of RAM. It's the GTX 1650 Super, which is less powerful than the 1660's, have 4 GB of RAM.
If you need a new GPU right away, and you're planning to keep your existing workstation for a while longer, then just buy a GeForce GTX 1660 Super and be done with it (at least for a while). The 1660 Super costs around $230. There are currently no desktop Quadros that are worthwhile at this time as they are all either too weak or too expensive, and they all cost substantially more money than a GeForce of the same relative level of performance.
In addition to enabling GPU acceleration for effects and resizing/scaling, you will gain hardware GPU-based NVENC encoding to H.264 or HEVC with the 1660 Super. The Tesla-architecture FX 3800 does not support NVENC at all.
Really don't know anything about hardware, so may I ask: Does it matter which brand? and how significant is the GPU's RAM? I found GeForce GTX 1660 Super offers with 4 or 6gb.
