Hi,
For good graphics, you would either need to go for a GPU server or a dedicated server that has integrated graphics.
However, this type of server is the higher tier specification and expensive.
You can let me know what kind of EA and configuration you are working on and we will provide our recommendation for your usage.
For most trading platforms and EA, DLL, and indicators, you do not need GPU spec. You can consider a high-end high-frequency CPU power would be sufficient.
