Suggets me everything mobo memory and cpu

If you're going into gaming, the 650/680 chipset is catered to the overclocker, persay. Other than MSI 975x being known to downclock ram, those 2 should be solid boards.
 
The P6N is a fairly new board, but should be very overclockable. I for one, would go with the newer p6n, but either one would be good choices.

I would look at Asus p5B Deluxe WiFi or Gigabyte DS3 965 chipset boards...

But those ones doesn't support sli and what if I want to go for sli  
 
Isnt the MSI p6n sli a good buy? or what? remember Im on a budget

See this thread for more P6N info.
