If your looking for more ways to benchmark your system using real world applications as opposed to synthetic methods (FutureMark etc.) Zardon of KitGuru has just made mention of a new update to his real world benchmark script designed for Adobe's Photoshop. It can work with Photoshop CS5, CS4 and is also compatible with Photoshop 7 (but the results will differ depending on what version you run).
Zardon has gone into extensive detail on how his script works, how to prepare your system to run it effectively and the sorts of scores you should be expecting from your hardware (assuming your system's in good shape). If you've read the full article about it here and would like to try the latest version; V1(4), you can download it here.
