hello guys, i use a 4770k(4.3 ghz oced ). i want to buy the next GA102/GT102 ( however they call it). i think this will come out within 2 months of 1180 release, may be as geforce titan. i have been using the 1080 for 2 years plus ( bought it within 7 days or the release ). now my question is if i want to buy the G*102, do i need to change my cpu ? will it bottleneck ??
