The bad news is the key - [Home Desktop Upgrade](https://blog.michaelfmcnamara.com/2007/10/home-desktop-upgrade/) - Last week I decided to sink some money into my slowing aging desktop computer. I upgraded my 9 year old 19" Dell CRT to a 22" Samsung 226BW Widescreen LCD and my eVGA 6800GS to an eVGA 8800 GTS 320MB. I have to say I'm pleased with both components.
