AMD fix this problem. There is a huge Open GL bug in after effects.
When using certain effects such as CC Slant and CC Burn and few more effects in After Effects, the system crashes (BSOD).
I have confirmed this with 3 graphics cards. 4870x2, 6950, 6970. I used after effects with all 3 of the cards and when ever I used those effects my system would instantly BSOD.
For those use After Effects try it on your own. Create a new composition, create a solid object, apply cc slant and play around with the settings. your system will BSOD instantly.
Here are some people having the same problem.
16 GB Kingston RAM
1 TB Hard Drive
