1024x800 the new standard?

For a long time now the standard for designing web sites have been to make them look ok in 800x600 and up; is that standard still valid?

Do you think that it's ok to design sites with a minimum res requirement of 1024x800 (800x600 users can scroll side ways if needed) or should the 800x600 still stick?

Ofcourse it does matter what type of site you are designing - I am considering switching my flowing layout on my ranking sites (www.hardwareranking.com) to a fixed 1024 width... what's your thoughts on this?
