Not going to be any modding here soon.
Haven't had a chance to get into town, and I ended up having to pull the 8400GS completely, and switch back to onboard video.
Unfortunately, the onboard is a 6150LE - which won't run Fallout 3 at all. Nor, by extension, the GECK.
Will run Oblivion, but I'd have to scale my video settings way back, and I'm not sure I want to go to the trouble of rebalancing the whole mess twice more.
Played some Zero Hour. Found out I can still wipe the floor with three hard AIs single-handed. With an ease that makes the whole endeavor boring.
CoD4 is in the same boat as Oblivion. It'll run... but not at 1024x768 - where I normally keep it set. Have to switch back to 800x600, scale down the effects, etc etc. Again, not sure it's worth the trouble.
Never realize how godawfully boring your pathetic life is until you lose your primary source of diversion.
Depressed now. Joy.
