Hi there. What motherboard do you have right now? Also, what speed of CPU were you looking at? I use the Asus A7V133 and the 1.2Ghz TBird (200Mhz bus), which came factory unlocked, so I run 9x133 and get the 266Mhz bus. It saves a little on the pocketbook, yes, but how long are you willing to wait? I'd assume that once the 266Mhz bus chips ship out, they are going to set the prices of the 200Mhz bus ones down, so you could probably get the 200Mhz 1.2Ghz cheaper and still run the 266 bus by running 9x133. I guess it depends on how soon you need the CPU and how much you are willing to shell out for a new CPU. Those are just my opinions and experiences and I'm not reccomending anything.
Hope this helps.
