I am still in the lengthy process of building my new rig and I originally started with the GTX 770. But have since changed that to the 780. Now with the new 970 and 980 cards coming out should I consider one of them instead. Yhe 970 is about $200 cheaper than the 780 but it seems the 780 might be better in some areas. The 980 looks great but it is about $100 more than the 780 3gb. What do you guys think?
