You should upgrade your 486.
Try again

Intel i7-920 clocked to 4.0 GHz
12Gb of 1800MHz DDR3 RAM
2X HD6970 2GB
3X 22" 1920x1080 monitors in Eyefinity
2X SSD HDs (one for OS and one for games)
Asus Xonar DX soundcard
But my system specs are irrelevant, the guy posting the pictures on this very thread has already said it is unplayable on his system. I dare say it is better than a 486.
