Driver RSS feeds are always useful (and yeah, ATI still is mentioned here too despite being "gone", haha):
http://www2.ati.com/rss/catalyst.rss(nVidia decides they don't need one however...anyone got some other one for them? Google doesn't help, on either the American or UK site!)
Asus, even though they have a pretty bad website, do a RSS feed for every single item on their site, which is darn useful. Find the product and there are custom RSS feeds for them. Eg this is my motherboard:
http://support.asus.com/rss/RssFeeds.aspx?product=1&model=P7P55D&SLanguage=en-usGaming link; who doesn't know about Savy Gamer for cheap(er) deals?
http://feeds.feedburner.com/Savygamer (also there are ones for each system if you don't want everything;
http://savygamer.co.uk/categorised-feeds/ ) - always nice.
I'd start recommending virus scanners and firewalls but don't want to bother; MalwareBytes is by far one of the best free malware scanners though if you need it. I still need to see if there is a better (free) firewall then Comodo sometime too.
