Yeah, specs would be great. I just bought a new computer this week because my older one (Which is less than 2 years old) has been running like s*** for a long time now. Dunno why, but it became bogged down with just running slower and slower over time. Surprisingly it ran Crysis on mostly medium graphics and it has only 2 gigs of ddr2 ram and a 256 PCI-E video card and a 32-bit OS. i forget what processor it had, but im sure it was less than 2 ghz.
This new pc came with an AMD Phenom II X4 910 2.60 ghz processor, 8gb of ddr2 ram, 512 ddr3 PCI-E video card, and a 64-bit OS. havnt tried Crysis yet, havnt been investing any time into my older pc games anyway, still trying to pass the time waiting for AvP by pillaging achievements out of my Xbox 360 games. Im praying that this PC can run AvP on High detail smoothly.
I betchya they release the demo AFTER the game is released to the public next month. Seems like thats how developers are doing things anymore, i don't see demo's for a lot of good games until well after the game has been released..
