AMD 7 Series Chipsets (with a Phenom II X4)

Often an ATI/AMD motherboard will be sli certified with the nvidia chipset as opposed to crossfire certified for AMD. I dought the onboard amd video board will provide the upgrade path to SLI.
The 770 and 785G boards are more budget enthusiast compared with the 790GX I believe. Although I have read some reviews say the SB710 doesn't have ACC in the bios all three mentioned here do. The Nvidia chipset's do not presently have the ACC code available in bios that I am aware of.

Thanks for the reply roonj,

At this moment in time I will not be upgrading to either a CrossFire or SLi configuration. I am more interested in whether an nVidia graphics card would significantly produce lower frame rates with an AMD/ATi chipset, than a motherboard with an nVidia chipset, such as the 750a? Hopefully this is not the case.

Regarding the South Bridges you are correct. It seems that the SB710 South Bridge does have AMD Overdrive but without the ACC, whilst the 790GX does list ACC.

Finally would the processor, a X4 965 in this case, perform better on a 790GX than a 770? This is possibly the main sticky point so far. If overclocking wasn't taken into consideration, eliminating the lack of ACC on an SB710, is there any difference performace wise.

So far it seems that I will be purchasing the ASRock M3A790GXH/128M for just under £75. This is simply because of the South Bridge offering ACC.

All further help is greatly appreaciated.
