ATI Radeon X300 Reference PCI Express Videocard
 

What I will be stating is that if you are moving to the new Intel LGA775 specification or the new Athlon64 PCI Express motherboard and you just need a basic 2D videocard, the X300 based alternatives on the market will make you more than happy. If you are even considering gaming, do yourself a favor and upgrade to an X600 if you want some decent playable framerates on any of the more recent or newly released games on the market.
