Well I would mate if i not been running slimmed down OS images since day 1 with my 2500K I ekked out every last rpm I think and without doubt at 3.7GHz the H97 Pro ( equal to Z97 if non overclocking ) with Haswell refresh was noticeably faster in desktop. When I say noticeable to me mate I talk in 0.0 's But I got to admit it surprised me somewhat, almost to the point I get crazy notion of running benchtests with my Card and SSD before I built for mate. lopl I think a H97 Gamer and stock i5 ( save money on cooling and CPU ) so more left for GPU is a good option when you don't have quite enough. Lot better its seems then H67 etc. was for mine.
