Hp Compaq 6300 pro microtower best gpu to upgrade?

If that is the same PC that you have, go for it. The GTX 1050 Ti is the best card available for a SFF PC. I have one in my Optiplex 790 SFF (i5-2400). Plays anything I toss at it at 1080p high to near max settings. Which PSU comes with that HP? Can you link me to it so I can check out the specs?
 


So I actually have the tower version my dad has the SFF, both have a 320 watt psu I can switch pc's with him if necessary.
This is a link to my model https://support.hp.com/us-en/product/hp-compaq-pro-6300-microtower-pc/5232874/product-info
I currently have the Zotac Geforce GT 610 Synergy 2GB https://www.zotac.com/us/product/graphics_card/gt-610-synergy-2gb
and well it's way outdated can't play higher end games without severe lag
 


Thanks can't wait till the 1st to buy it ^w^
