So after getting my new GPU, I have x2 gtx 550 ti laying around. I was thinking on using one of them as dedicated PhyX but I dont know if this will improve my performance or just bottle neck the 780 ti and therefore run the 780 ti run alone.
So is not worth it to use it as phyx?, I cant sell both since im giving away my older pc to my sister so she need at least one card, then again if i do sell them i can add a 750 ti for it
If your sister will be gaming, I would sell both 550TI's and get a 750TI. If she won't be gaming, just sell one of the 550's. Or just let her use the integrated graphics (If you have it)
