I have a choice of 2 PCs, my main purpose, besides internetting, will be video ( and photot ) editing

Both have an Intel Core 2 duo processor with 2x 1,8 GHz, one the Intel chipset 965C but 2GB of PC4200 SDRam, the other the chipset 945GC with 2 GB of PC5300 SDRam
( my selectionis limited, I am in japan whee all PC come with japanese OS, but I need english OS - see my regarding question at the Vista forum )

Which one would you prefer for editing?
