Hey guys. I'm looking for a GPU for gaming and editing. My current system is an i5-4570 on an asrock z87m pro 4 with 2x4gb of Adata XPG 1600mhz ram. I have a 525 watt 80 plus psu. I built it recently and chose these parts specifically because we are later in the lifecycle of this generation and i'd like to upgrade when the new stuff comes late this year most likely. I will most likely be upgrading to asus z87 pro with i7 k series processor when the 5th generation comes out, and i will be looking to get a GTX 880 when that comes out. But for the time being I need something to work for cheap because my camera is starting to give me a lot of problems and getting a new camera takes priority over upgrading my system further. I'm looking to spend under $200. I use adobe photoshop and premiere for my editing. Would a GTX 660 be alright on a small psu like mine or would recommend a 650ti or wait on the 750ti?
*please note I live in Canada so the prices are about 10-20% higher IN GENERAL.
