But why is the price is so high than the 3.2. It seems 3.2 GHz cost Rs. 14,000/- and 3.4 GHz costs Rs. 23,000/-. Is this true?? What is the current price of the 3.4 GHz & 3.6 GHz? Motherboard: In the 915P & 925x series they say that there is one ATA 100. So how to connect a DVD-ROM, CD-Writer and the old Parallel ATA hard disk. How to use the RAID.

What is the price of the GeForce PCX 7570 SATA Hard disks: Is the SATA based HDDâ€™s has any performance boost than the Parallel ATA HDDâ€™s ????
