I play FO3 on Windows 7 64bit and yeah, it occasionally crashes to desktop, but we're talking about once every 10-15 hours of gameplay, and with the abundance of autosaves everytime you exit a building or enter one, I never lose more than 5 minutes of playtime.
I'm on Win7 Pro x64 as well and the only time Fallout 3 crashes is occasionally when I exit the game...and at that point, well, who cares?

Could be drivers not playing nice causing crashes for people. I'm using an nVidia GTX 285 and a Creative X-Fi ExtremeGamer sound card...the drivers seem to play nicely with Fallout 3.
Hahahahaha Yet another reason consoles are superior to your PCs. Watching you guys squirm at system requirements and list parts that total to over $150 makes me glad that I'm a proud 360 owner.
Lol...well, all I can say is keep telling yourself that if it makes you feel better about something. You go out of your way to bash PC gaming so much around here it must be a sore spot for ya. :laugh:
I mean, I have a 360 and several other consoles. Why do you suppose I buy almost all of my games for my PCs? I just gave my nephew my over-4-year-old castoff PC and it runs Fallout 3 better than my 360 does...and it's more stable. Just sayin'. Squirm? Did you mean, "scoff?" I don't even
read system requirements.
Really, though, why bother trying to pick a fight? We're all gamers and all of the versions of the game have the same content. Are you mad that you can't use mods or something?
Anyway, as many have said, the requirements for NV are extremely likely to be the same as Fallout 3. I haven't had to upgrade my PCs in a really long time because a lot of the games I've been playing are cross-platform, which can be run well on hardware from 2006.
