Ok, so whats the best HSF for damn socket a? and whats an average overclock estimate.
Is an overclocked xp-m betta than a 3000+ 64
The SLK line from Thermalright is pretty good. It's what I've got and it's solid copper. Weighs a fair amount too. It doesn't come with a fan but generally good aftermarket heatsinks don't although there still are good ones like the Volcano 12+ Couple that thermalright with a vantec tornado and cooling won't be a problem, but sound will be. The tornado's are loud. I have a fan controller so I keep mine at halfway most of the time unless I'm gaming but then I have headphones on so I can't hear it anyway.
As far as estimated OC it generally varies from person to person of course, but I have yet to see a XP-M barton core that didn't hit ATLEAST a minimum of a stock 3200+ XP which is 2.2GHz which currently would be better than a 3000+ AMD64 which is stock 1.8GHz....the 64 however does have twice as much L2 cache but until a 64bit OS comes out to fully utilize that 64bit processing the 400MHz over that chip will be more noticable towards the speed of your system.
There's atleast 3 people here including myself that have an NF7-S v2 motherboard and XP-M chip and none of us had a problem hitting 2.2GHz. I'm sitting at 2.5 although I can get it to run 100% stable at 2.7GHz I choose not to run it that high because it requires a lot of voltage and a little more heat.
4W4K3 has the same board, but has a 5w 2600+ XP-M and he can hit 2.5GHz on a lower Vcore than I can. Also I believe Leonidas has a 2600+ XP-M and the same board and he also can hit the same speed with a little lower voltage.
At newegg the 35w 2400+ XP-M's are no longer on the website. Don't know why, but they were in high demand and the price kept going up. the 45w 2600+ XP-M will still OC as good if not better than the 35w 2400+ XP-M
