You want a NEW board because you believe there is a problem between your current ASUS board and your SSD???
What exactly are the problems / symptoms?
There is no good guarantee that a new board will solve your problem, simply because you -may- encounter the same chipsets on other boards as well.
If you are sure that nForce is to blame, you'll need to switch to an AMD chipset... here are two examples between 50 to 60 bucks... cheap boards are more difficult to find there...

But before you go there, check if a newer BIOS is available for your board, and if a newer FIRMWARE is available for your SSD.
Next, are you using AHCI? If not, you probably have speed problems with the SSD. Trouble is, if you switch on AHCI on an existing system, you might need to install from scratch. DON'T switch it on if your current system has been setup without it, but plan to reinstall at some point from scratch with AHCI on from on the beginning.
Next, check driver settings (cache on/off? write-through/back?) and switch on buffers if they are off.
Next, absolutely DO make sure there is a problem with your specific SSD and some boards or chipsets --- GOOGLE!!
