Just in your shoes man -

Go for the 4200 or the 4600. Anything else will be SUPER FUCKING OBSOLETE AND POINTLESS. GeForce3 is on it's way out to pasture, and you can get the GeForce4 for a very reasonable price. As SOLIDUS said, MX is shit, and I wish I knew that before I shelled out my hard earned cash for it a year ago, but oh well it worked. Anywho, get the 4200 or 4600, you can get them as low as 212 off of pricewatch for a 4600, and 175 for a 4200.

You WILL see a graphically improvement. Definately. Especially if you're playing games like MOH and BATTLEFIELD. The damn things are fast and big.

Only thins is, make sure you do a BIOS FLASH or you may run into some problems with the GeForce/MB/and XP.

Fuckers.
