MOBO Upgrade Help Wanted!!!

Hi, I'm looking to upgrade my motherboard as I can't attach any more internal hard drives to my current one and it doesn't support 6.0mb/s so I'm not getting the full benefit from my SSD.

My current Mobo is an ASUS M4A77TD, it has 6 sata ports.

I will also upgrade my RAM, probably to this:-
http://www.amazon.co.uk/Corsair-CM [...] omputers_2
Corsair CMZ16GX3M2A1600C10 Vengenace 16GB 1600MHz CL10 DDR3 2x8gb sticks. This will leave me with the option to upgrade to 32gb at a later date if I have 4 RAM slots.

Here is a list of my current components I want to keep in the setup:-

AMD Phenom II x4 955 3.2ghz
Crucial CT128M4SSD2 128GB M4 SSD
NVidia Geforce GT220
Asus Xonar DS
LG Blu-Ray Burner
3 Port IEEE 1394a Firewire PCI Card
Front usb/multi memory card reader.
COOLERMASTER SILEO 500 MID TOWER CASE

Can anybody suggest any suitable MOBO's and what are the attributes/ main features I should be looking for? Looking for something new also so built in usb 3.0 is a must. I onle use a wired internet connection so no wi-fi but bluetooth would be nice but not all that important.

Thanks for reading eD.
