    Should use the new GPU programming for Nvidia and ATI (CUDA or something?)
    Like my CPU has 4x 3ghz... Thats about 9 ghx effective.

    My HD48700 from ATI has 1,3 Tflops. (Thats ALOT, but its GPU...not a CPU)
    And a 1gb gddr5 GRAM. So if that could be used it could check alot faster for colors. But still...most people don't have 8xxx series and up from intel or 38xx from ATI that support that technology :/
    There are a few misconceptions in this post.

    First, slower CPU's can handle both scar and Runescape if they change priorities. Not every loop that runescape does is dedicated to graphics rendering. Most are just loops to make sure some event hasn't occurred.

    The next is the effective ghz statement. Umm, yeah, 3ghz quad core != 9ghz cpu (or even a 12 ghz cpu...). Each core is independent of the other. A quad core won't make runescape run faster then a single core at equal speeds (EG both at 3.0 GHz), because runescape isn't multi-threaded it won't go any faster then if you had at 1000core cpu vs a single core machine.

    As for CUDA/programming on the CPU. Well, for scar you would see no benefit. Scar and scar scripts are VERY serial in nature, there are some things that can be made parallel, but for the most part scar would run slower if it was dedicated to the GPU. (GPUs excel at tasks that are highly parallel and involve mostly floating point calculations.)

    So for Future reference, TFlops, Cores, Clock speed, ect != speed. Yes, they represent some of the capabilities of a program, but they don't equate directly to speed. (For example. a single core of a current quad core run at 3.0ghz is much faster then the old P4s run at 3.0ghz, somewhere in the range of 20-30% faster. Ghz isn't everything)
