What reviewers say

Both reviews found strong application performance and better value than the higher-priced Core i7 models. Expert Reviews particularly favoured it for video encoding; Alphr was more cautious about the premium over the i5-750. Both considered the cheaper i5 sufficient for many users, with Hyper-Threading most useful in demanding threaded work.
