What do you mean by this... your tired of complaiments that are good?
The correct sentence is the second one "She built a high-performance CPU".
The first sentence should not contain a comma and is incorrect. The third sentence is incorrect because there shouldn't be a dash before CPU. The fourth sentence is incorrect because CPU is not written with dashes.
