I'm running the 7025 and the brisbane 3600+, overclocks very nicely. I've gotten it to do 2.6ghz with little effort (with 667 mhz memory, lol, I really should have gotten the pc6400, oh well). Just set memory timing to 533, up the voltage like... 2 ticks from default, and it ran stable at 2.6ghz on stock cooling (cooler never felt hot, probably could have gone higher on stock) for about 5 hours before I got bored of running prime95 twice in the background while surfing the internet and playing mp3's 😛
The TF7025 definitely gets my vote for simple design, as this is the first overclock I've ever done. (old motherboard was intel , lol, can you say locked tighter than a chastity belt? 😛)
