And here's me struggling with my 2007 Intel Celeron M 1.6 GHz laptop. I maxed out the RAM last year to 2GB from 1GB! This is the machine I use every day! It does the job, just. The internet gets heavier each year though so it'll soon be time for an adblocker! Youtube videos seem to get harder to decode as well.
I bet an X5000 would seem heavenly fast compared to what I'm used to!
YouTube gives you VP8/9 encoded videos by default, if you install h264ify add-on for Firefox/Chrome it'll force YouTube to stream h264 encoded videos which your video card should be able to play with it's hardware decoder.
Install ublock origin for your sanity/security too
