Could someone tell me my bottleneck and what I can do about it?

Mobo: MSI K9N2 SLI Platinum/ K9N2 Zilent (MSI-7374)

CPU: AMD Athlon 64 X2 6400+

Graphics: Nvidia Geforce GTX 580

Memory: DDR2 8 gigs



I think it's my CPU... What's the best CPU I can put in there? I saw the list on MSI but I've heard people putting even better CPU's in this board than the list says but needing to do something with BIOS.

This is for gaming by the way.

Would it make sense to build a completely new PC?
 
The phenom II 965 is the best you're gonna do.

It will hold up pretty well with a 580. The DDR2, ancient chipset, etc aren't helping but they are minor compared to the CPU.

Only other option is to replace the board memory and CPU.
