Well:
Minimum system requirements - Windows: Windows Vista / 7 / 8
Processor: Intel Core i3-2100T @ 2.50 GHz / AMD Phenom II X3 B73
Memory: 4 GB RAM
Graphics: ATI Radeon HD 4850 or NVIDIA GeForce 9600 GT
Hard Drive: 14GB free space
Mouse, Keyboard.

So it looks like you're way under the minimum specs. It's still possible I guess, but I wouldn't expect it to run well, if at all.
Maybe someone else on a similar machine can confirm if they've tried it?

yeah, thought so.

i just hoped that, as you said, the actual requirements might be much lower...

thanks.

I've a good 6 years old configuration near minimum system requirements:
- Core 2 Duo T9400 @ 2,53 GHz
- 4 GB RAM
- ATI Radeon Mobility HD3870

With high graphic settings and high resolution (1920*1200) it's not playable with less than 10 FPS but with low graphic settings same resolution game is comfortable with 25-30 FPS.

Minimum system requirements is not far from truth.

I will try with lower resolution but I think a GeForce9300 GE which is approximately 7x lower than my graphic card doesn't have a chance...
