Best Nvidia chipset for AMD?

There is absolutely no performance difference between the current NVIDIA chipsets for AMD (GeForce 8200/8300, nForce 750a SLI, nForce 780a SLI) except for some fancy features (i.e. SLI x8, SLI x16, support for EPP memory etc.). Summary:

- nForce 750a SLI = GeForce 8200 + SLI (i.e. the PCIe x16 link splits to x8,x8)
- nForce 780a SLI = 750a + nForce 200 (PCIe switch for x16,x16)

The older chipsets have no future (only HT 1000MHz; no support for the upcoming 45nm processors).

The full name of GeForce 8200/8300 is "GeForce 8200/8300 and nForce 730a" (it's a single chip, but is called as if it were a two chip solution). nForce 730a/720a is a cut-back version of "GeForce 8200/8300 and nForce 730a" without onboard video. Summary is here.

The HD audio controller built in these chipsets are exactly identical. The difference appears only with third-party audio codecs (ALC888, ALC889a etc.), but only when you use analog, there is no difference if you use digital (S/PDIF).

BTW if you use a Radeon card, it has its own HD audio controller (7.1 ch with HD 4xxx), independent of that of the chipset. GeForce card lacks it so that it supports only S/PDIF pass-through from the onboard audio codec.

Many people in this forum including me are using a GeForce 8200/8300 mb/Phenom and are very happy with them. Personally I didn't find anything flaky.
