Hi guys, I'm unsure as to whether I need a sound card for my pc build or if my graphics card already has one installed. I'm going to be using the Asus HD 7770 2GB AMD Radeon Graphics Card. Any replies would be appreciated!

Its usually the motherboard that has integrated audio. This will be communicated to the graphics card if you choose to use an HDMI connection. The DVI connection (most used with HD monitors) does not carry sound and you will have to plug into the motherboards audio-out for sound.

No, it's not built into the graphics card. It is, however, almost certainly built into the motherboard.

So no, you probably do not need a dedicated sound card.

oh okay, I'm afraid I'm a bit of a noob. My Motherboard is this: Gigabyte GA-78LMT-USB3 Motherboard Phenom II AMD Athlon II Socket AM3 AMD 760G Micro ATX RAID Gigabit Ethernet (rev. 4.1).

Has this already got one built in?

Pretty much any motherboard has built-in audio, and in modern times its passable quality compared to what used to come onboard. So no, you dont "need" one. If your an audiophile and would appreciate the extra quality from a dedicated card, I suspect you would already know the answer to your question :D .
Myself, I use an ASUS Xonar DGX sound card. I haven't noticed any increase in quality per se, but I definitely have noticed the head-phone amp. Having more power pumped to my headset means that it can go louder and has the power to drive the more bass sounds without getting crackling. If your using a decent headset/headphones, I recommend you look into a cheap $20-30 sound card, if only just for the amp.
