What you need to consider is the pc case dimension and whether the new card and psu will fit in it. Otherwise its a good upgrade to consider.
Big thanks for you help Hellfire. A friend stated that if we go for an upgrade on the psu we may have to upgrade the motherboard too for the GTX1060. We don't really have the budget though,so wondering if the Socket H3 (LGA 1150) is adequate? Thanks
