Hi I bought this video card: XFX GeForce 8800 Ultra 768MB DDR3 SLI PCI-E, it has x2 6-pin socket connector, do i need to use them both? or with 1 is enough? im using a 590w power supply unit, thank you for ur patience

Hikari is right, you need to use both.

Generally graphics cards tend to come with instructions, you might want to look at those first
