When looking at the 3.06 it indicates:
To ensure your system is enabled with Hyper-Threading Technology, look for the Intel Pentium 4 Processor with HT Technology logo.Processor - 1 x Intel Pentium 4 3.06 GHz ( 533 MHz ) - L2 512 KB - OEM
Does this mean if you already have the 3.06 look for the logo?

Have allready droped $300 in unit.... 500gb HD, 2g mem, HIS 4670 video card, 420w PS. 3.06 processor with fan will be $90. Will there be that much more speed from 2.53 to 3.06 with HTT? What do you mean by getting old, as in age, use or both. Unit has not had heavy use or abuse. THKS
I would go oem for the 3.06 if you decide to go ahead and get it. Starmicro has it listed on pricewatch for $30. Your old heatsink should be ok for it. And the 478 platforms are getting old. Your board could fail at any time; bad caps are common for some boards from this era, so read up on changing out a motherboard if you haven't done it yet. I also recommend a small ssd for boot up when you upgrade to a newer platform with sata II or III. The boot times are impressive, and they are twice at fast installing windows 7.
