So im sold on the whole core 2 processor even though im an AMD fan :roll: However im at a loss as to what the mobo would cost and the selection of them right now, or can i get them now.
Well, if you want to overclock (as you say below), you'll want a standard enthusiast board. They will run you anywhere from $150-$250. There are boards that are currently Conroe compatable, so you can go ahead and buy them now.
Also how powerful a PSU would i need?
A standard 500W powersupply would be fine, unless you're looking to have 5 hard drives with two Cross-Fire Cards with bling-bling lights.
I am looking to overclock so i suppose i would need a liquid cooling and the whole bit.
Depending on the chip, the standard cooler can overclock quite a bit. If you buy a lower end version (say, the 2.13Ghz one), you could probably expect an easy overclock up to ~2.7Ghz on stock volts/cooling based on early reported results. If you buy the XE, you could probably overclock up to around 3.3Ghz on stock volts/cooling. With a good air cooler (such as a Tuniq Tower), you can probably hit 3.6Ghz without too much trouble with some extra volts.
Water cooling is (in my opinion) a waste of time. Good heatsinks (such as the Tower) work almost as well with a lot less complication. If can be worth it if you get a water chiller (one that chills the water to about freezing rather than just ambiant temperatures), but those cost a lot.
Hope this helps.
