Why GFX card with more RAM?

CPU has to provide enough data for GPU to work with. It can be a problem if CPU has to calculate AI of many aircraft or ground vehicles.

I had stutters both online and offline with stock speed of my CPU (2.8 Ghz) and happy to run it on 3.8Ghz online or offline with about 30-40 AI around. I guess if you can take a dual-core to 4.5Ghz+ it may be sufficient not to bottleneck gtx560 but sometimes a 3rd core may be needed to avoid stutter or fps drop. I think no one did much testing on this. You can check out results of some benchmarks of many various systems here http://translate.google.com/translat...hp%3Ft%3D68723
Easy to understand and make conclusions.
