Il2 is actually an old sim and doesn't really require the fastest hardware available. Some mods will cause a frame rate hit, but generally speaking, Il2 runs just fine on fast, single core processors and what would be considered high-end video cards of two or three years ago. I could run it just fine on my old system:
AMD Athlon 4000 over clocked from 2.2 to 2.6GHz
2 MB of DDR-400 RAM
Nvidia 7950GT video card
Soundblaster Audigy 2ZS sound card
Windows XP Home edition.

My current system absolutely smokes Il2
Intel Core2Duo E6850
2 MB of DDR2-800 RAM
Nvidia 8800GTS factory overclock
Windows XP Home edition
