hello all, i have been updating my system and it now consists of a 6400 x2 a 512 4870, 8 gigs of ddr 800 ram running at 4-4-4-12, a creative xfi elite pro, and an antec 850 psu, all running on vista. my issue is that my system seems to still be bottlenecked somewhere and i have the feeling that it is the motherboard. i get that feeling because it is an old Nvidia Nforce 570 series, the m2n-sli deluxe. im debating moving up to an AMD produced board with the 750 SB but im not sure its going to be worth my money to do so.
if anyone knows anything please let me know!

What tasks are making you think it's being held back? I will add that although you have the fastest AMD proc for gaming and such, it is quite a bit behind Intel's fastest offering. I'm not trying to say "Go Intel", for I am an AMD supporter myself. But you still have a pretty fast machine,even if it's not totally cutting edge. A faster motherboard is only going to give you a couple more percent in performance, unless you have something wrong with your current setup.
Just for the heck of it, check your HT setting. I had an issue with my Nvidia board's BIOS setting mine to 1x (200 mhz) instead of the full 5x. I had to update it to get it to run at the correct speed. There was a definite lag in my machine and it took a while to figure that one out.
My system is very similar to yours, except for the Nvidia video cards.

Well the 750SB is more geared towards the black edition processors. It's suppose to help overclock the system by allowing the FSB increase on the CPU to not F* up the stability of the board. Also the 6400 gets really hot and is already towards the limit of the Windsor core, so I'm not sure you'd get much benefit out of it. The fact that nVidia boards don't always like ATI cards AND the fact that your board is PCI-E 1.0 could limit your system, so in that regard going with an AMD board could help out. Anyway that Asus board should have some easy to use overclock tools so try them out and if you get a significant increase from it them it's your CPU that's the bottleneck. You should also try updating the nForce board drivers.

If your CPU is bottlenecking the system then you could upgrade your CPU. Looking at the Asus website it seems that your board supports up to a Phenom 9850 as of board revision 1502. Take a look at it yourself here.

What are you doing anyway that you feel that system isn't enough?

You will see exactly 0 performance increase from a new motherboard keeping all other hardware the same.
