When is the Due date on this puppy? I understand is a Chipset. on what mobo's will the be available? anyone knows about the price?

Im going to buy another computer sooner or later (i was going to do it in 1 month from now) but with computers timing is everything, i don't want the coolest, newest, fastest money can buy, because i dont have it, but a very scalable system, that i do want.

My current setup is

Intel 1.6 Ghz
512 Mb PC133 RAM
Aopen GF3 Ti 200
Integrated Sound Card
LinkSys 10/100 LAN Card
80 Gb HDD
CDRW 16x/10x/40x

Does SCSI improve a lot the performance of the machine, i have access to exchange my U2W SCSI Controller for a SCSI 3 (160 Mb/s) but i need to get a drive, is it worth it?
