Get a 6600GT or you can do what I did. Buy an X600Pro and use a BIOS to flash it to an X600XT or make it run at the same speeds as an X600XT. If you need more then just Overclock. Currently, all Pentium 4s are 90nm and they run cool enough to be overclocked. I just don't know why everyone is *****in' about the Pentium 4s running hot and mine is OCed very high and it doesn't run hot on stock HS/F.
Make sure you get 2 x yyyMB sticks of DDR2 400/533 memory. They must be identical sticks to run Dual Channel. You should definately run Dual Channel since Pentium 4s need all the memory bandwith they can get. And Dual Channel provides them with twice the bandwith as running them in single channel.
