The PC version is absolutely not a port. This was a conscious decision early on and has meant that the PC version has been developed in parallel with the consoles as a project in its own right. We wanted to support and reward PC gamers who have stuck with the platform and upgraded their software and hardware to the latest specification.
The PC version is enhanced in the following ways…
Enhanced DirectX10 and 10.1 render path
Support for 32Bit and 64Bit Windows 7 and Vista
Optimized for Dual and Quad Core Processors
Certified for Nvidia 3D Vision (Not available on console)
Support for Window and Full Screen modes
Enhanced for SLi

Do you support multiple monitors and ATI's Eyefinity technology? If so, does the support go beyond an extra-wide view? Could you perhaps put the in-game map or some other info on a second screen?
We do support Eyefinity across multiple monitors. As Just Cause 2 features some of the most breath taking vistas seen in any game, being able to render those across 3 monitors results in a truly unbelievable experience, if you have invested in multi-screen hardware you certainly won’t be disappointed.
