If you haven't got an Ageia card, don't bother.

User Rating: 3.5 | CellFactor: Revolution PC
I'll give Cellfactor: Revolution this much: it has a really kicking soundtrack playing at the main menus, and it has pretty good graphics. But ff you haven't got an Ageia card, don't bother. I have a reasonably good computer, Windows XP Pro with >2 Gb RAM, 7800Gs video card, 3.2 Ghz Intel CPU. Granted I'm on AGP still but it's top of the line there. I play Command and Conquer 3, Company of Heroes, Half-Life 2, and even Oblivion on med-high settings and I get decent performance. But Cellfactor: Revolution was a slide show on my machine, and I tried restarting many times, same result.
