This it what he bought. Dell Inspiron i3650-3132RED Desktop (Intel Core i5, 8 GB RAM, 1 TB HDD) NVIDIA GeForce 730. He wants to buy my msi gtx 970 I know how to install a gpu I just want to see if i could with his setup.
1050 or 1050 to is a better choice as poster above says. For that 970, he'll need a new PSU and to just hope that card fits his case and that it had enough ventilation which I would not count on.
you would need a low profile gpu thats both small and not power hungry like a gtx 1050 low profile edition msi has one and if your psu is atleast 350 watts it should handle it fine
