need opinion & suggestions please

Unless your running Crossfire (dual ATI cards), that motherboard is uneeded overkill. Save yourself some money. Both of these boards down below are the new P45 chipset just like that Asus board you posted, but cheaper in price. Any of the P45 boards will work fine with that cpu you chose. btw, that 1200 memory is a bit deceiving. Those boards support standard DDR 800 PC 6400 memory. It's cheaper, runs great, and overclocks better. Go with the DDR 800 PC 6400.

Also a cpu really worth looking into is this one below. It's the "little brother" to the E8400, and just by moving up your FSB (Front Side Bus) to 9.5 x 333 you can have it running at 3.16GHz. That means for $60 less you have the that cpu running at the same specs that the more expensive E8400.

Good ideas and advice by why_me , if you're not going to overclock, then stick with the E8400
