BTX is the new formfactor for motherboards arriving later this year.
It will put the CPU down low by the front intake fan, and the add in cards on the back of the board. It is primarily designed to improve airflow with faster and hotter CPU's.
With it you'll see the new PCI-X cards replacing standard PCI, and PCI-X for graphics which will replace the AGP. DDR2 will also appear with the new mobo. It should be the biggest thing to hit the home PC since the Pentium.
Basically every internal piece of hardware you own now, will be completely useless with the BTX mobo's even the case and power supply.
So, yes, if your current hardware config is good for you know, but the speakers aren't go for the speakers and save your cash until the new toys start hitting the market.
If you search back a few weeks, Larry started a thread regarding the new Intel chipsets that are beginning to hit the market. Now IS NOT the time to upgrade.
As for the speakers, if you have the cash, the Logitech 680's are awesome! 500watts, THX certified, Dolby and digital DTS encoding built in. These speakers are sure to start a riot at 1AM in the morning.
