I'm a noob. Trying to piece together a PC for gaming/streaming. Here's my build so far: http://ca.pcpartpicker.com/p/cxMrdC I would like a GTX 970 for the cheapest price but my question is is it worth it to spend 20-40$ more for something a little better for performance/quality or would I be fine with just the cheapest one? After picking a GPU if you don't mind picking the cheapest good quality PSU would be great, thanks!
