Upgrade tactics: CPU or GPU?
If you have the budget for CPU upgrade, you’ll see the most performance from that, but you wont see any noticeable performance upgrade if your motherboard is Socket AM3 and only a slight performance upgrade if its AM3+ and can take an AMD FX8350. And I stress..the performance gained from a Phenom II to a Bulldozer will not be that great in Gw2.
My suggested upgrade path would be at least an Intel i5 4590+compatible motherboard+RAM and leave your 4870 in it for the time being. It is starting to show its age old but Gw2 will still be bottlenecked by the CPU Single Core Performance before the GPU majorly bottlenecked.

A video card won’t need a motherboard and possible ram upgrade.
HD 4870 is a 130-140 watts, since we don’t know the size of your power supply is, in terms of 12 volt wattage, so R9 265 or GTX 960 in terms of power needed.
