I was a little disappointed first seeing the requirements for TWS2 but so far it's turned out that it players very well, as long as I keep to Normal unit size and Medium graphics settings. I can even play battles online without any problems. Still, I have been thinking about upgrading my computer so I can turn the unit size up. This is what I have:

Processor: Intel(R) Core(TM)2 Quad CPU Q8300 @ 2.50GHz
RAM: 8.00 GB
Graphics Card: NVIDIA GeForce GTX 260

I was wondering what the best thing to upgrade would be to improve performance. It seems pretty obvious I have enough RAM. I wasn't sure which of the other two needed replacing more, though...
