If you can find one @ retail price, I would recommend installing a RTX 3060. on a side note, get a better CPU heatsink/fan, and a USB 3.0 card. The Xeon E3 1270 is the same CPU as your planned i7, but without integrated video and a little lower power consumption.
I am hoping to upgrade the workstation, with that being said, i need help determining the capability for the GPU. My current build; CPU:Intel Xeon E31225 3.10GHz RAM: 4.00 GB (2x 2GB) GPU: Nvidia Quadro 600 PSU: UNKNOWN   My Goal is to use... CPU: Intel Core i7-2600 (Sandy Bridge) Quad Core LGA115 95W (here)  RAM: Crucial (4x 8GB) DDR3L-1600 UDIMM (here)  GPU: UNKNOWN PSU: EVGA 700w BR (here)  I need to know what should i upgrade the GPU into...   thanks!
