Question Overclocking a HD 7870

So, I have been trying to overclock my GPU, since it bottlenecks nearly all my games. It is a Sapphire HD 7870 GHz Edition and I'm using Sapphire Trixx instead of MSI Afterburner because it is the only software that allows me to change the voltage. if I overclock it a measly 5MHz I get artifacting on my main monitor (but not my second monitor) even if use the max voltage and power limit. If I ignore the artifacting I can get it up to 1150 MHz on the core. The reason why I'm curious is because I've seen people online (http://m.hardocp.com/article/2012/04/26/sapphire_hd_7870_oc_edition_video_card_review/3 ) getting way better overclocks and no artifacting, and I'm wondering if I'm doing something wrong.



Specs:

CPU: Intel Core i7‑2600K
RAM: HyperX 16GB DDR3 1600
GPU: Sapphire HD 7870 GHz Edition
