Either SNB CPU won’t tax the
Either SNB CPU won’t tax the HSF enough to cause a noise problem so I’d run the retail cooler unless there was a problem.
At idle and most use cases a 65W SNB based CPU is close enough to a 35W one in power usage that unless you are running in a constrained environment (or really don’t need the extra frequency) it may not be worth the additional cost for the lower wattage CPU. There certainly are scenarios where the balance tips towards the “T”, but I don’t think that you’ll see it when opting for a case like the GD05B.
Other points:
1) Do you need the analog capture provided by the HVR-2250? If not, the AverMedia Duet is a much better deal for the same feature set.
2) Get a bigger SSD (I know it’s already been said, but worth repeating)
3) With Lynx available, I think it is a better option than the older AMD IGPs. But it’s important to keep in mind that they still have some driver issues to sort out on the platform.
