If I plan to overclock this CPU to 3ghz with only air cooling, (yes, I would buy an aftermarket cooler), does it really matter if I get a B3 or G0? Any cooler recommendations to go with it btw?
For 3 GHz either will do. G0 will do it slightly cooler.
That's my G0 with a Thermalright Ultra 120 Extreme+1600 RPM Scythe Slip Stream (90 CFM). I have a Cooljag 110 CFM fan that I will be using after I mod it (won't work with the clips like it is). On that screen shot the AS5 on the Heatsink is about 30 hours old. They recommend 200 hours for curing, so I'd expect temps to drop another 1-2C.
I got mine for $276 US Shipped. Find a store that will guarentee a G0 if you want to go that way.
