 ==== Final Thoughts ====
+   * Testing proves that the Cirrus Logic card is **as-fast-as** or **faster-than** the Tseng Labs ET4000AX in every real-world benchmark. That's no surprise as it's a much later design.
    * The Am386DX-40 really doesn't benefit much from the ISA overclock to 13MHz; in Doom it is clearly the processor that is by far the most restrictive element.
    * The Tx486DLC-40 going from cpu cache-disabled to the default cpu cache-enabled setting results in a **12%** improvement in Doom low-detail frame rates and **13%** in high-detail.
    * The Tx486DLC-40 going from cpu cache-disabled to the most optimised cache-enabled setting results in a **17%** improvement in Doom low-detail frame rates and **a staggering 35%** improvement at high-detail.
-   * Boosting the ISA clock from 10MHz to 13MHz with the DLC brings just a **1%** improvement to Doom low-detail frame rates (to be expected, since we're not pushing many pixels!) but more than **6%** in high-detail.
+   * Boosting the ISA clock from 10MHz to 13MHz with the DLC brings just a **1%** improvement to Doom low-detail frame rates (to be expected, since we're not pushing many pixels!) but more than **6%** in high-detail. In certain benchmarks this is noticeable, but in the real world many ISA cards would be way out-of-spec at such a setting; in that case the 10MHz ISA clock is a good, stable increase over the ISA 'default' standard of ~8MHz.
    * From non-optimised cache-enabled settings to most-optimised shows gains over just under **5%** in low-detail modes and **19%** in high-detail Doom timedemo results. //Who wouldn't want a free 19% of extra performance!//
