I just bought a 2GHZ CPU with 256MB PC3200 DDR SDRAM, it also has an Integrated Radeon XPress 200 graphics card. I know 256 MB is the minimum but I have read that it usually is sluggish at that amount of memory. Now I'm thinking I should have bought the 512 for the $60 more it costs. I can always upgrade for $25, but what a bummer and hassle to have to have it installed. I just got it and am about to install it, so I hope all goes well!
Okay well, I just found out what I feared. This game is useless with only 258 MB of RAM. VERY VERY SLOW. Screen freezes. Takes forever to zoom in and out. Just forget about it if this is the amount of RAM you have. Looks like I'm gonna have to get the 512 to do any kind of gaming on this computer.
