I have an old Dell laptop with a P3 800MHz,512MB ram, and 20GB Hard drive. This thing is a tank. The ram is already maxed. I have seen people successfully run W7 on low specs but don't know how well it will run compared to XP. It does have dedicated graphics and a pretty high res for such an old laptop. How well do those torrents with supposed "lite" versions of Win7 work? It seems like most of them remove important features. I'm probably just going to keep it to play around with then sell it on craigslist for $15-20. So if Win7 is not functional I'll just leave XP on it.
