back on topic- absolute speed. not necessarily OC to get there, but tweak OS, and bios settings. use the 3.25beta versions, and the -advmethods, and -forceasm flags to get higher concentration of gromacs WU that are worth more, and will be finished sooner, esp. in a given time line comparing tinker WU's to gromacs WU's. more points will be accumulated by running gromacs. only gromacs will use the assembly codes from the -forceasm flag (sse).
