wow this is another approach to the problem.So far I received 2 suggestions: the higher clock the better since not every programs support 2 cores; and the gpu is the most important since the lower clock is not too neccessary but the lp2 ->the higher the better. Now you say the cpu is more important, not the gpu.So it means core2duo with lower GHz(1.5) with middleclass gpu;coreduo with higher GHz(1.8) with lower-middle class gpu; coreduo with lower GHz(1.6) with lower top class gpu; or just a simple turion x2(1.7)with middle class gpu??
