4400+ is not that worth than 4200+ as both have same core clocks. Only diff is the L2 cache that 4200+ has 512KBx2 while 4400 has 1MBx2. But perfomance difference is negligible but price difference is much. If u want somethin above 4200+ then go for 4600+.
I suggest go for a 4200+ along with ASUS A8NE. Never go for A8N VM or ATI chipset mobo as with such a proc nd A8NE u can squeeze monsterous perfomance from it.
