text: [apple users]  which power mac is better? dual 2ghz powerpc g5 processor - 1ghz frontside bus/processor - 512k l2 cache/processor - 512mb ddr400 sdram - 160gb serial ata - 16x superdrive (double-layer) - three pci slots - ati radeon 9600 - 128mb ddr video memory  ====or======= dual-core 2ghz powerpc g5 processor 1ghz frontside bus per processor 1mb l2 cache per core 512mb of 533mhz ddr2 sdram (pc2-4200) 160gb serial ata hard drive 16x superdrive (double-layer) nvidia geforce 6600 le (128mb gddr sdram) thats a hard question to answer. having the dual chip rather then dual core is better but! having 1 mb chace is better then 512k and you need the extra cache to get extra performace. in the end i would end up picking the second just because i like nvidia cards much better then ati. if they both nvidia cards on the other hand i would pick the first one.  in fact i change my answer the first one sense i would be upping the ram and video card anyway. and see if this is one of the modles i could up the cache with
