I have an HP H8-1214 desktop, it has an amd fx-6100 processor and a GTX550 ti gpu with 600 psu that I installed. Anything else I can do to push the performace of this? It does really well for the most part but would like to run WoW on ultra settings with no issues. I can run it on ultra as is, but I do get big framerate drops in heavy populated areas etc.
