UPgrading my DDR3 board

[BTRY B 529th FA BN]

I guess the big question really is does a person want to go dual gpu's or a single gpu. I'm not really sure. I just am looking for a new DDR3 775 board for my Q9650 + watercooling setup. Price doesen't matter as I'm seeling off my Q9300 & mobo to help furnish the cost of a new mobo. My H20 components are all copper and I guess you aren't suppose to mix metals. So, if you're sure of an all copper pre-built H20 board let me know my considerations. But, I'm partial to Asus mobo's...

Thanks for your thoughts,
