Well I'm planning to build a comp, but I'm mostly concerned about the motherboard xD

I was thinking of getting this:

Motherboard
Gigabyte GA-MA780GM-UD2H - moederbord - micro ATX - AMD 780G

Processor
AMD Phenom II X4 920

Ram
Corsair Dominator TWIN2X PC8500 4GB DDR2Kit w/2x 2GB XMS2-8500 dimm's, CL5-5-5-15, 1066MHz, E.P.P, DHX, with FAN

Power supply
Corsair Powersupply 650W Black, ATX/EPS,120mm Fan, 8xSATA, SLI

Hard disk
Samsung SpinPoint F1 750GB SATA2

graphics card
Club3D Radeon HD 4870 1GB GDDR5 PCI-E,Overclocked Edition, DVI/VGA, HDCP, HDMI


What more should I get or change? I thought about maybe changing the motherboard for a: Asus P5QC, P45, Socket-775, DDR2/3,ATX, GbLAN, Firewire, PCI-Ex(2.0)16. I don't really know xD I build my broke down comp with the ex of my older sister, wich is.... impossible now

[EDIT] My first choice motherboard has a build in Ati Radeon HD 3200, so is it possible to just use my current videocard with it? ATI RADEON 9800 128mb (it sux, I know.... ).
