You need to factor in the cost of a decent power supply as well as for your graphics card. Don't put expensive new hardware on that power supply.

Rest of your system would be fine for that upgrade, although the 1070 is still a fairly good card at 1080p, I'd question whether a 3060 is enough of an upgrade. A 3060ti would be a far better upgrade path.
