I'm trying to finish picking out the parts so i can build my gaming PC. I live in Australia and i am building a PC initially less than $2000AUD now it may be $2500AUD hahaha. I would like to buy a GPU that can last me a while and i was thinking either the Gigabyte GTX 770 2GB or 4GB in an SLI configuration, or a GTX 780. I need help on whats the best option and are there others. I dont want to crossfire AMD cards because there are problems. I would like to play most games in Ultra settings. i enjoy FPS games and would like to max out games like BF4 when it comes out. Especially with next-gen games on the horizon. I know about the Maxwell cards as well but i would like to know if the cards i have mentioned in this topic will be suitable for 2, 3, or 4 years. any help would be great! Thanks.
