Video Editing Software Problems!!!

[CaptainFrosty7]

Hello all, I have downloaded the Go Pro Studio and iMovie for mac and both do not seem to work right. I am running 10.10. When I go to open iMovie i just get the iMovie quit unexpectedly window and that keeps happening. For the go pro studio, if I try to convert more than one clip at once or one clip sometimes, i get that quit unexpectedly window as well. Please help, Thanks

I found the problem and it seems that both applications did not like my Radeon HD 6450 gpu but they work fine with the Intel Integrated 4600 graphics.

Any suggestions on a good graphics card? I like the gtx 970 or the radeon r9 290x but i don't know if there is support yet.
