Thanks!I bought asus gtx770, which is much more powerful and I can do a higher reclock. (first you need some voltage fixes in nouveau.ko and later put it in latest kernel and recompile it, later do update-initramfs)
From: 07: core 405 MHz memory 648 MHz To: 0f: core 1050 MHz memory 7010 MHz GTX770 it is a much better option that any Intel GPU.
