Overclock questions

[PC_gamer5150]

I am pretty new to Overclocking a graphics card and wanted to ask
is a overclock of 1215 good from a stock clock that was 980 base and 1033 boost? I use msi AB and GPU-Z
Now i am seeing 1215 when i play a game,it used to be 1066 when i gamed.
also wanted to ask if this is not considered a high overclock what should i be going for?

Which card do you have? I'd keep raising until you have stability problems or out of control temps. Then work on raising the memory speed.

best stability tests for me are Metro Last Light bench on max settings except no physx, Tomb Raider bench on max settings, and Firestrike.
