AMD 2600+ upgrade to D805?

Hey guys i need some advise

2,5 year ago i build this pc
AMD sempron 2600+
MSI KT6V
1GB pc3200
Radeon 9600XT AGP

now it keeps on crashing and its getting slow and i want to trash it. Only im low on money so i thought the D805 would be a good solution.(?) Overclocking it to like 3,6 -3,8 Ghz.
Now i would like to point out im low on cash lol so ive found this motherboard.

It's got DDR and DDR2 both dual channel and PCI-E and AGP8x. This would mean i can use my old stuff and upgrade when ive got the money. But my question is: Can this motherboard take on the overclock? Or can i just better save some money till i can also buy new memory and a videocard for it?
On the article about overclockin the 805 they use the Zalman CNPS 9500. Are there any other good coolers except watercooling?

yeh i did but only a few shops sell the 915 here and every shop sells the 805 so i think thats why the difference is that big.
