| First question; according to every single source I could find, the real-world performance gains at higher clock speeds were negligible. I decided to get DDR 800 RAM with a nice big heat spreader so I could focus on lowering the timings, an area that DOES put out a real world gain.
And for overclocking, it depends on how you define strain; I am not pushing the processor to the limits of stability, but I see nothing wrong with pushing it until the die reaches a reasonable 60C, a pretty conservative number (many consider 75C an upper limit). 40C full load is excessively low. |
