If you want speed with less money, you have to get an ATI card..
Radeon 9500 pro gives a very high performance for a low cost.
Whatever you do, do NOT buy Geforce4 MX420. I personally wouldn't buy any of the MX line cards, theyre basically just souped up geforce2's. In MX420's case it's not even souped up, it performs as bad as the Geforce2MX SDR!!!!
Remember that the display card is THE most important factor with your gaming performance. It's the wrong place to save. A Pentium IV 3Ghz system will give you a whopping 15-20 fps in most modern games if it's equipped with MX420. A radeon 9xxx on the other hand will blow your fps through the roof with the same machine.
One thing I forgot when discussing with Tumor: Intel CPU's have now built in a system called cassandra. This hardware system enables microsoft to kill your computer with a security update (if you don't have a legal copy of the OS), it enables MS to stop you from running ANY programs that are not licenced with MS, it enables MS to stop you from playing any MP3's or AVI's which are not paid for etc. funny stuff.
Basically the system will not let you boot up your computer if a wrong checksum is found with OS. It's the ultimate Big Brother of computers..
If the Digital Millenium Act goes through, none of the Intel owners really own their computers anymore.. Because your computer will be controlled totally by a third party, Microsoft and RIAA.

AMD has reported not to add this function to any of it's CPU's. A big reason why I'm going to stick to AMD regardless of the Intel price.
