View Full Version : 750a vs 980a chipset

I can't decide between these two motherboards:



All I'm really concerned with is performance. The only difference I can see is that MSI claims that the 980a can overclock the RAM higher. My understanding is that the 980 is just a rebranded 780, and a 780 is a 750 with more features and not added performance. Am I correct in this?

I have the NF980. Just built a new system using it. Seems like a nice board, but right now I'm having what looks like heat problems with the on board GPU/south bridge and something else. The GPU and another sensor are reporting numbers of 81-117c. the other reports around 90c. 81c is 177F which is too hot to touch yet I can touch the heatsink for the SB. While it is hotter then I'd like it to be, I can keep my finger on it. Though I do live in the desert....

The nforce drivers for the chipset on the nvidia site are newer then even the download drivers on MSI, but that is normal for motherboard companies.

Which ever you get, try for a BE cpu. I got the 945 95w as the 955 was $30 more because I wasn't looking to overclock the cpu. But even to overclock the memory controller which can take a bit (CPU-NB), you need a BE and now there is only a $10 spread.

Also. I used the Thermalright 128SE heat sink with an Artic Cool 120mm PWM fan and it keeps it at 40-42C under full load and is still too quite to hear with out taking the cover off and sticking your ear next to it. The Corsair 950TX power supply I think is a bit louder though you have to be right next to it to hear it as well. I don't have any video cards yet so it doesn't really spin up it's fan.
