Radeon HD 7770 Lagging In World Of Warcraft

I'll post all of my specs here to start it off:
I'm running on a pre-built Emachines (I know.. I know) and I've done my own upgrades to it but I suspect I need to get a new mobo/ram and that's the cause of my issue...

My Specs:
ASUS Radeon HD 7770
AMD Athlon II X2 260 (3.2 Ghz Dual Core)
Ram: 8 GB DDR2
PSU: Corsair GS 700w

Model: Emachines ET1331g-03w (Don't ask me why.. but every specifications site has some version of a motherboard that I don't have and says only 6 GB are supported)

Here's my issue.. I was running an ATI Radeon HD 4600 and I could run the game fine but I had to turn Shadows to low and view distance to Good and now that I have a 1920x1080, I would have to turn everything to low to play it. The fan also stopped spinning so it was time for an upgrade.

So I plunged and got a new PSU and the Radeon HD 7770 but when I first plugged it in, I noticed I was only getting 5 fps... so I uninstalled the AMD drivers, downloaded the latest drivers from AMD and the issue seemed to go away.

However, I'm getting like 10-20 FPS in Orgrimmar and my CPU usage shoots up to like 100%. I get high CPU usage on just about every game I play and yesterday I had an issue where the GPU kept crashing WoW. I tried turning on AMD Overdrive and my CPU usage shot to 100% and the computer crashed.

For some reason right now, CPU usage is hovering at around 50-60% and my FPS went back to 5 FPS for some reason.

UPDATE: I turned on Starcraft 2 and the CPU is all over the place. It'll be at 80-100% for a few seconds, then it'll go down to 30-40%. It keeps fluctuating :\

it doesn't seem to be lagging bad on SC2 though, despite having high CPU usage pretty much all the time.. it's sticking around 70% right now.

  1. I am pretty sure your experience in cities are going to rely on a lot more CPU power than you have available. There is lots of processing necessary to keep up with all the activity of so many users, and that dual core is probably a bit short on power. Maxed out CPU usage is generally a sign of a bottleneck there, especially if the GPU does not appear to be working that hard.

    As I suspected...

    My CPU as soon as I turned the game off went to 2%. My GPU activity never gets high though... well. time to upgrade to a new mobo/cpu since I have the best CPU I can get for my motherboard :\

    It can only handle up to 65w so yeah, that limits me a LOT...

    Here's my upgrades I'm thinking about getting:

    (Yeah, I really need a new case)
