It could run office apps, play non-3D gamers, browse the web, etc. all pretty fast. And this was without using nLite.So yeah, if you are not of the category to install a thousand useless tools/games just for the sake of trying them out, then WinXP will run fine on the machine you describe above. I was able to run XP on the following config using an nLited version: 233MHz, 64MB RAM, 3GB HD Pretty decent for web browsing and word processing...
