Slow performance on new computer?

[Pycno]

Ill keep this short, Ive fiddled with my HW lately and discovered its actually vastly underperforming.

I tested a friends computer with specs seen below, it yielded 500+ fps in Grizzly Hills on lowest gfx settings and 100+ fps with graphics set close to the highest values. This was with a low-end graphics card.
i7-920
4gb value ram, dual channel
Geforce GTS240 (costs 150$ or so)
traditional platter hard drive

Compare this to my computer (with specs seen below), I get 119 fps at the same location with every setting at its absolute minimum. I forgot to turn off antialiasing in the screenshot below and it has 4 fps less. All addons and even sound was disabled.
i7-980x
6gb 1600mhz cl7 ram (triple channel)
Radeon 5970 gpu
raid-0 intel ssd's

Pretty much to conclude, my performance is trumphed by a computer at 1/3 of the cost bought over a year ago. The difference is pretty large as the older computer is several times faster


My performance:

I think I found the perp, will test it later

I blame ATi.

Didn't you mention that you are unsure of how to turn off your Crossfire on that card? WoW wasn't designed for Crossfire or SLi so that could be hurting you.

Having Crossfire forced to enabled certainly doesnt help, but I found the source of the problem, it was the HDR graphics patch I had downloaded a long time ago. My older computer didnt have the same issues with it and it surprises me that it should have such a negative impact on the performance. Must be a bad .dll or something.. I disabled it and fps went from 119 to 850 on lowest settings, performance in Dalaran and with max graphics went up significantly as well and Im pleased with the performance now

You have a monitor with 850hz refresh?

[Pycno]

They are 60hz and I normally play with max fps set to 60, I only disabled vertical sync to measure the performance

As a side note, my old Eizo crt monitor has 160hz refresh rate, this made my screen update up to 10,4ms faster then a 60hz monitor. Not bad in a game where every margin counts.

where and what exactly did you disable? was it an HDR setting in the ATI catalyst control center or a wow setting or what?
