Will my build be CPU or GPU limited? Basically I've been trapped on low settings at like 1600 render distance, so I was wondering if it's my GPU or CPU which needs an upgrade:

An Intel Core i5 4570 at 3.2gHz, an Nvidia 650 ti (standard, not boost) 2gb with 8GB RAM (1x8gb Kingston) on the side, all on top of a standard consumer m-ATX motherboard (shouldn't actually impact performance)

Heat never tops out about 70c and I've never gone over 380w of my 450w PSU even on stress tests.

Cheers guys ^-^
