ok. my parents are going to america which means i have a rare opportunity to buy a 1080 in a much cheaper price than where i live (about 30-50 percent difference). i don't have a good computer, i bought a gtx 960 last year, and other than that my computer is 5 years old pretty much. i have a GA-PH67-DS3-B3 motherboard with a i5-2400 cpu. can i get decent performance with this system and a 1080 with a later upgrade of the whole system or will it definitely bottleneck the card and i should buy a whole system instead?
