But Quad's are really bad for gaming as they are underpowered and no game supports 4 threads yet, which is where dual cores come in, but in sins it won't make difference until it is multi threaded.
Thats not true at all, you using windwos and other programs in the background, they do require some calculation all the time. So if the game is programmed to use 2 cores, the duel core will have to share one of its cores to other things which is running in the background. On a Quad the program will be able to have 2 full cores all to it self.
Edit: Didn't even see this was an old thread. While we're at it: If we can run that many ships.... why will the cap be so low that it's unfeasible to actually play a large map (unless you want to play a game of "catch the enemy's fleet while it rampages through your empire and vice versa")?
FYI this took me about 2 full days where one core was running the game all the time. Once you get beyond the 1000 units it will be unplayable.
Still a cool post though (the 10k ships)
actually i got to 20k ships

Oh and Sins DO support multi cores

SgtDPilla i hope the modding stuff you asked for will help you see its not playable beyond the 1000's units, and that beta 4 supports multi cores
