I'll second Paul's recommendation on cpu-z .  Find out what stepping your quad is too, as that'll have an effict on what might be recommended.  If that's a B3 running at full load, the temps aren't that bad for a stock machine.

I'm assuming that you've already got core temp or something like it since you list 4 temperatures.

You won't find true hardware raid on consumer class boards.  You'll need a server class board (no overclocking) or after market raid card for that.   The raid that comes on the consumer class boards is driver based, but it's good enough if you don't need ultra performance.

Well, you have a G0 stepping quad, which is a good thing .

On the low end of the overclocking scale, I like the Gigabyte ga-p35-ds3r .  It doesn't have the 8 pin cpu connector (it has the 4 pin one), but seems to run quads very nicely regardless of that.  It has onboard raid 0, 1 5, 10, and jbod (driver based but decent) and will do just about anything you'd want.

Stepping up from there is probably the Gigabyte ga-p35-ds4 .  It adds firewire, an 8 pin cpu power connector, and a second pci-x 16.  It also has the raid you're looking for.

That, with a good HSF should get you well above 3.2 ghz at reasonable temps.

One thing you didn't mention which I'll bring up here is the power supply.  That's going to be critical for overclocking.  Do some research there as that's probably the most important part of a quad overclocking setup.  Myself, I'd lean towards a single 12v rail supply of at least 550 watts and very good quality.  The last one I bought was PC Power & Cooling Silencer 610 and I'm very happy with it.

65 is no big deal for that cpu.  I wouldn't want to run it there permanently, but it's far enough below spec that a couple weeks like that won't hurt it.  If you haven't already, just pull the side off the case  and run it open.  That alone is usually good for 4 or 5 degrees .

Nah, I'd wait until you get the new mobo before addressing any cooling issues you have.
