Motherboard advice needed

I would like some advice on a new motherboard. I would like to go ASUS board and chipset combo with DDR2 ram, HDMI, Intel core 2 quad, socket775, 2 or 3 sata hookups, ATX, PCIe x16, a PCI express 2.0, HI def sound, something in the 150 pound or 300 USD range. I use the computer as my TV no gaming. I have a new graphics card, new power supply 600 watt, also something that is mot too new. Thanks for any info and your time.

Yo, something like this should be ok, it fulfills your requirements, except the HDMI which you shouldnt need because you said you already have a graphic card. The on-board sound should be ok, but you can always buy a dedicated sound card if your unhappy.
