I'm about to buy a GPU for my new PC and I only plan to keep it until Pascal's launch then I'll switch and give the old card to my gf or resell it. I'm tied up between three cards all at the same price point and was looking for suggestions/opinions on what to go with. I have 300$ to spend and found a Evga Classified 780ti, Asus Strix 970, Powercolor PCs+ r9 390 all for 290-306$. Any ideas?
