HP Prodesk 600 G3 MT (GPU Upgrade?)

[Buttonaholic]

Dear Forum,

I recently bought a HP ProDesk 600 G3 MT i7-6700 3.4GHz 16GB 1TB HDD Desktop Tower.

I plan to buy the propriety 400 W power supply, add a  M.2 SSD, and add a GPU.

I attempted to follow @NonSequitur777 ‘s Build:

(https://h30434.www3.hp.com/t5/Desktop-Hardware-and-Upgrade-Questions/Upgrading-HP-ProDesk-600-G3-MT/...), 

but the problem I’m having is I don’t know what GPU to buy for a few reasons:

- I want the best possible performance without a bottleneck for my i7-6700 CPU. (RTX 3060 bottlenecks, GTX 1660 underperforms)

- I will only have a 400w PSU

- It has to fit inside of the tower, considering the drive cage.

@Buttonaholic,

Yea, as you can probably tell, the HP ProDesk 600 G3 MT was a fun upgrade project!

Personally, keeping budget in mind, I would very strongly recommend that you upgrade your PC with an i7-7700 or an i5-7600 which will help minimizing the bottlenecking you are referring to.  You can get an i7-7700 for under $50, such as this eBay purchase option: Intel Core i7-7700 SR338 3.60GHz Quad-Core 8-Thread LGA1151 CPU – Tested Working | eBay, and an i5-7600 for even under $30, such as this eBay purchase option: Intel Core i5-7600 3.8GHz Quad-Core Processor SR334 LGA1151 | eBay.

At least with an i7-7700K, my HP-branded RTX 3060 did definitely not bottleneck.

Anyway, consider a GTX 1660 Ti or GTX 1660 Super.

Kind Regards,
