So basically I've been looking to upgrade my PC lately. As I know nothing about computers I asked a friend for some help and they directed me to the GTX 970 to replace my AMD Radeon R9 M360, as well as a new PSU (650w, as opposed to my current 280w). Was ready to buy them today when my brother told me I should wait since the GTX 1070 / 80 is being released soon, and I might be able to get one of those instead, or get the 970 for cheaper. Personally I really don't want to wait too long, but are price drops that significant that it might be worth it? And should I expect to need more than 650w if I end up getting the 1070?
