For 60fps ultra 4k you need sli 980ti, sli titan x, cfx fury x, or equivalent.

A single 980ti will play 4k ultra on most games at around d 35+fps

Also, get the os from g2a or Microsoftsoftwareswap. It's 1/5 the price and legitimate copies.

thanks atmos, i was wondering if one 980ti would be enough, but no one said anything about it to me before. I'll look into it more. Regarding to OS, whats the best way that you think i should go at it. I'm was planning on WIN 8.1 OEM 64bit, but since WIN 10 idk what to do. Should i still get WIN 8.1 or try for a cheaper WIN 7 then upgrade for free to WIN10?

g2a is probably the easiest, you dont have to deal w/ a person. But the reddit page is the cheapest.

 

I'd say just grab a copy of 8.1 pro and then upgrade to 10 when you're comfortable. By the time you upgrade most of the bugs w/ 10 should be worked out. An 8.1 OEM is perfect, and alwasy get 64bit. Windows 10 copies are expensive atm compared to 8/7

Id really suggest a higher wattage PSU aswell, you may find 6 months down the line that the single 980ti is struggling with 4k and to add another, in which case that PSU won't supply enough food to the prison queue. Id suggest a 850w quality PSU now to save you $$$ down the line

 

I also second going to G2A for Windows, I just got 8.1 pro for my daughters PC build for £22. That's money saved towards your 850w PSU. I got my Fractal 1000w for £95
