Over at Planet Doom there's news update dealing even more with Doom 3's minimum specs. Apparently PD heard a rumor that Windows 98 wouldn't be supported by Doom 3, so they went and asked Activision about it. Activision of course confirmed that Doom 3 was only meant to run on Windows XP or Windows 2000 and nothing lower. So, if you're still upgrading you may want to add XP or 2k to your shopping cart as well. As a bit of a side note, if you or someone you know is in college them you may be able to snag a copy (upgrade or full) at a considerable discount from the sticker price.
