I am going to build or buy a new computer and one of the main criteria is to be able to play C2C on max settings: gigantic map with 50 civs. Maybe good folks here can offer some advice which hardware parameters are actually important for Civ 4? I am currently thinking: Processor: Processor speed / throughput seems to be rather important in order to reduce wait times in late games. 4 cores is rather standard nowadays but it seems that Civ 4 can actually not benefit much from anything more than 2 cores. Intel Core i7, some model with 8MB L3 cache, 4 cores. RAM C2C on max settings looks like to be a memory eater. So 4 GB RAM (in a 64 bit OS) is a must, but is there much point to increase the RAM size to 8GB? I have heard that Civ 4 can not use the extra memory. Graphics Card Discrete GPU is a must here. I have heard that Nvidia GeForce works better with Civ 4 than AMD Radeon cards, though most likely both are fine. But when searching forums I have noticed that people have had problems with cards from GeForce 400 and 500 series.
