I think I can he be of help. I'm currently using a P4 2.8Ghz with HyperThreading, 512Mb DD1 @ 200Mhz, a ATi Radeon 9800 PRO (AGP) with 256Mb of DDR1 @ 324Mhz, and a 122Gb IDE HDD, on Windows XP.
It quite badly needs replacing in truth, the HDD has began to fail, my sister infected and crammed it with malware, thousands gifs, adware etc... and there simply isn't enough RAM to multitask, or even unitask. However, when playing games, apposed to general web browsing, it's quite proficient. I would be quite confident to say it would do alot more had it been new.
It has managed the following:
Unreal Tournament 2003 (All full specs, online, 40+ FPS)
Dawn of War : Soulstorm (1920 x 1200, 20 - 40FPS, all high)
Neverwinter Nights (1920 x 1200, all high, smooth framerate, online)
Zoo Tycoon (All high, Smooth)
Fallout 2 (Flawless)
Diablo 2 (Online, Flawless)
Mark of Chaos (A little lag even low specs, later missions I doubt would be playable)
Morrowind (Flawless, high FPS, all high)
In regards to Fallout 3, I'm sure it would not play, however I had some success with Doom 3 through Ubuntu, so I'm sure it would have played on XP.
The standard for games in the past half a decade seems to be 2Gb of RAM, and of the last 12 - 18 months, Dual core as a requirement has become a common sight on packages.
