New HD7970, not the performance boost I was hoping for.

Specs:

CPU: AMD Phenom II x6 1090T 3,2GHz
Motherboard: ASRock 870 extreme3 r2.0
Graphics card: XFX Radeon HD7970 Double Dissipation
Memory: 8GB Corsair Vengeance 1600MHz
PSU: OCZ ModXstream Pro 600W
OS: Windows 7 Ultimate 64x



I just bought a new XFX Radeon HD7970 Double Dissipation to replace my HD6870, and I feel like something is not quite right.

The main game that I play is World of Warcraft and I thought even with my old card I should be able to max all settings and be at 50+ FPS. This wasn't the case, but I wasn't distressed, as I might've had my expectations up too high.

Now that I have the HD7970 I am still having issues running this game at max settings.
I can get 60+ FPS in the open world when I decrease some settings like Shadow Quality, SSAO, Sunshafts, and View distance. It can drop to ~40 FPS in high populated zones.
but especially in 25-man dungeons my FPS takes a dive to 15-25 FPS throughout a whole bossfight. I've tried setting every setting available to the lowest possible, and my FPS will still not go above 40 in 25-mans.

It seems like something is keeping my performance down when things get rough, because my GPU Activity doesn't exceed 50% at the most graphically heavy fights.

I've also noticed FPS drops in other games, for instance Assassin's Creed 3. Doesn't matter what settings I pick, at some points in the game, like in towns, my FPS drops to about ~30.

Temperatures on my Graphics card are around 60 degrees celcius when playing World of Warcraft.
Temperatures on my CPU are around ~55 degrees celcius when gaming.

Could it be my CPU?

I'm at a loss here on what the issue could be.
If you have any suggestions, I could really use the help.
And if you need further info, I'll be happy to provide it.

Thank you!

Yes, your CPU is a dog. It always has been, unless the game is heavily threaded up to 6 cores. At stock clocks, it is even worse.

If you see your GPU usage lower than 99%...especially below 80%, that is because you are being bottlenecked by the CPU in most cases. V-sync can cause that too, but that would mean your FPS were at 60 for most monitors.

If you have 50% usage, there is no question the CPU is the problem, and turning up graphical settings should have no affect on performance (though shadows on WoW is heavily CPU dependent).

Download MSI Afterburner.
Open the application.
Go to Settings->General->AMD Compatibility Properties (bottom of page)->tick the "Disable ULPS" box.
Restart PC.
Try out WoW again, and see if your problem is resolved.
If not, go back to Afterburner and untick the box again (to re-enable ULPS - as disabling it isn't ideal, unless it helps with problems such as these)

If this doesn't help, then I'm not sure what else to suggest :O

Good luck, keep us informed :D

Thanks for your responses!

Esrever, luckily I play a ton of other games aswell, and I have noticed performance increases there.
So the money wasn't spent in vain :)

JRAtk94, thanks for the suggestion but sadly it didn't do anything for me :(.

If the CPU is the culprit, I was thinking of buying an I5-3570K. Would this be a drastic improvement compared to my 1090T?

Thanks again!

It should really improve your WOW experience, maybe not so much in other games but its a decent upgrade.
