Which Motherboard to choose?

I wonder if anyone would be kind enough to help me. I am looking at getting a new PC and wish to know what motherboard would be best to choose. I'm going to get...


CPU: 2 Duo E6600 CPU @ 2.4GHz 1066FSB 2x2MB L2 Cache
Memory: (2GB (2x1GB) PC6400 DDR2/800 Dual Channel Memory (Corsair XMS2 Xtreme Memory w/ Heat Spreader)
Video Card: NVIDIA Geforce 7950 GT 512MB 16X PCI Express Video Card
Hard Drive: 300GB SATA-II 3.0Gb/s 16M Cache 7200RPM Hard Drive
Sound: Creative Labs

and have the choice between
1. Intel DP965LT P965 Chipset LGA775
2. ECS P965T-A P965 Chipset LGA775
3. Asus P5N-SLI nForce 570 SLI

My main concern is that they will work ok with the RAM, as I have heard that there may be some problems with 800mhz. Is one motherboard that much better than the other? Overclocking is not an issue for me.
thanks in advance

Thanks for your advice l1zard,but sadly I can only choose form the three listed as it is the only options the company I am buying from offer.

I am just worried that the ram may have problems. The boards are all listed as only supporting 666mhz ram.

Just wanted to know if anyone has one of these boards and is using 800mhz ram
