Hi there, I've been immersed in Civ 4 for the past 3 weeks, and am loving it, having been a Civ 3 fan for a few years. It's been a long route to get it working though - firstly I forgot that I hadn't gotten around to installing DVD drive, so major disappointment that day the game arrived! Cost playing game so far £60. Then, every time I built a wonder the game locked up. After reading some of the posts on here, came to the conclusion it was the 3-year-old graphics card. New one arrives but I forgot when I upgraded the motherboard last year, I stuck with AGP, so PCI express graphics card ain't gonna work, doh! Resold on Ebay (couldn't send it back cos I had opened it ) net loss £25, plus new AGP 8x card at £95 = total so far £180! And while I was getting the graphics card sorted, I figured taking the ram up to 1GB would be wise idea, extra cost of £60 (I decided to exchange the 512 mb I already had for some with a copper heatsink in the name of a fraction extra speed). All-in total £240 to play (Just as well OH doesn't play, so he won't see this post ). But, I still have the same headache I endured with Civ 3, that being in the later stages of the game when I am running my large armies of mass-destruction, it all becomes mind-numbingly slow and clunky. So, to cut a long story short, is there another upgrade that'll remove this and make Civ 4 the truly mindblowing game it should be? PS I'm running a P4 3.2ghz, 1 GB RAM, Nvidia 6600 GT 256mb onboard. Cheers!
