A good deal if you know what you are doing. 4 units of the same GPU. Great if you are building a system for Local AI or 3d rendering. The Gigabyte Gaming OC is a tough reliable GPU, EXCEPT you will need to replace the thermal pads and thermal paste to get all these cards working at maximum efficiency.
These cards were well used, but still have a lot of life in them. I don't have time to replace the pads and paste, or shine them up so they are beautiful for the pictures. So, I'm just knocking the price down to an acceptable cost since you will need to do the pad and paste replacement yourself. If you know what you are doing, or just watch a Youtube video, you should be fine. The oldest card is in dire need, the 2 intermediate cards are just starting to show slow down, and the newest card you can get away with not replacing for a while should you want to save time. However, anyone who does serious work with these particular cards knows that you really need to replace the pads and paste eventually.
