Ok this AMD V INTEL crap is getting out of hand and sim city cannot multithread so don't brag about it if you have sim city running perfectly on a Quad core 3ghz. My idea is to compare pc's which could and could not run sim city without lag now if anyone would like to participate in the test e-mail me your system specs and when your pc starts to lag e.g. population when it starts lagging. Please do not lie if you get 3fps with a quad core just to make yourself feel better, no one cares about what how great your pc is, but what we do care is if we can identify the problem and find a fix for those who would be most grateful for the even if slight increase in performance, I for one would. Please participate and my e-mail address is djpenman@hotmail.co.uk. I am looking for the following information: CPU CLOCK BRAND (e.g. AMD Athlon64 4200 2.2ghz dual core) RAM CLOCK BRAND (e.g. Kingston DDR2 and how many sticks of ram you have such as two 1gb etc ) GPU MODEL AND CLOCK AND MEMORY IF POSSIBLE (e.g. NVIDIA 7950 400mhz core and 750 mhz VRAM SLI etc) Also if you know could you tell me your hdd specs such as rpm cache and size
