I'm building a PC for $1000 and I would like to know, which would make more sense for the best performance? Getting an i7 4770K and a GTX 760/770 Or getting an i5 4670k and getting a GTX 780? (I will be gaming, 3D modeling and some coding) I plan to add another card in SLI later,came I will be OCing, but I want this build as future prof as possible. Also, if I should switch to an AMD card at this price point, tell me please. Finally, what ever I should do, please be specific with the graphics card brand and name so I can find it. Thanks in advance!
