Well, yes there are bugs and issues in the stock game, but with the hard work done by the modders here it's a totally different experience. You can pick up an on-disc copy from Amazon for about £5 so at that price I'd say it's worth a go!
Modlist in my sig if you want recommendations, looks like a lot but it's worth it. Plenty of people here to help if you get stuck in your installations too. I run it on Win 7 64 with no troubles.
Welcome back & good hunting
