i have an i3 5005u which i think is good enough and an radeon r5 m330 2gb gpu which is too old. so my gpu bottleneckes my cpu right now and i will upgrade my gpu. i am about gtx 750 ti and gtx 950. but if i choose such good gpus my cpu might bottleneck it,so should i buy a new cpu despite my already bottlenecking gpu or a new gpu that might bottlenecked my cpu.oh. and i would like to know if it would be better to have an i5 3470 cpu with an r5 m330 gpu that will surely bottleneck the cpu or an i3 5005u with an gtx 750 ti/gtx 950 that might get bottlencked by my cpu?
