Asus ROG G20 AJ cant really handle everything

[Drippingclouds]

So as stated I have an Asus ROG G20 AJ the base model from Best Buy, and well it can really handle a WoW client along with HB. The FPS drops in PvP and in raids while in the lowest settings. So that being said I was wondering what you guys would recommend I do for some upgrades to help this console sized PC out. This is the current specs right now.
GeForce GTX 750
i5-4460 CPU @3.20GHz
8GB Ram

Trust me I know lol. But I have to work with what I have at the moment until I'm able to build my own.

Check you power settings to make sure that it is in performance mode, there is no reason that that pc should not be able to run wow and one hb client

Shes in performance mode but once I get into pvp say like ashran the fps drops bad even without a HB client running

Is WoW the only game that has fps problems? And make sure that you drivers are all up to date. Nvidia had some poor drivers a few months back and i was getting really low fps and i run an i5 6600k, GTX980 with 16gb ram.
