[SOLVED] Gigabyte HD 6870 really compatible for Hackintosh?

[ziynchen]

I installed Lion 10.7.2 and SL 10.6.8, both of them meets the same problem which is shown on the picture below. The graphic is a mess, every time I open a new finder window and move it, there will be many dots appear and even polygons overlay on the window. I tried several methods and follow the instructions from different guide on this website, but didn't work.

All of my parts come from the recommended build of tonymacx86, which is:
CPU: i5 2500k
MB: Gigabyte Z68XP-UD3
Graphic: Gigabyte ATI HD 6870
Memory: 16GB Corsair DDR3
HDD: Corsair SSD 60GB

Is Gigabyte ATI HD 6870 really compatible with hackintosh? Did anybody use the same parts to build the hackintosh and succeeded? I'm really thinking of return the graphic card to amazon and buy another one, do you have any suggestion for a compatible card?

Maybe your card is defective?

How to test the card to see if it's defective?

Isn't it obvious from your screen?
That, or your LCD screen is defective.

That's not a compatibility issue, that's a hardware issue. Either your card is overheating or it's on it's way out I'm afraid. What PSU are you running?

Try it with another screen and if you get the same results send the card back. You might want to see if the card does the same in another os though (Windows, Ubuntu etc) Also, have you overclocked any of your componants, I had some graphical issues when I overclocked my ram.

Is there any possibility that problem is from motherboard?

PSU is corsair 650W, I didn't overclocked or anything else...

I don't have another screen but I already test the screen on the laptop and it's good...

Do you think I should return the graphic card and get a same model again?

By the way, I tried to run Civilization on the system, snow still there but sometimes it will disappear for a second. The problem is not that big when I run a 3D game, but it's really annoy when on the desktop...
