Thank all of you for your advice. I plan to wait for ivy bridge so there's no hurry.
I had a test just now:
OpenCL and OpenMP don't make much difference here……OpenCL won't reduce performance. I had hoped that OpenMP will give a boost on quad core computers.
Anyway, openAL do give a speed up over alsa……although it has nothing to do with the problem.
Under linux, the peak temperature of cpu is 80C. Windows with D3D9 is 90C. The maxium safe temp of my cpu is 120C so I don't have to worry……
