Sound card for music/movies

[hazelmania]

Hi,

I wanted to buy a soundcard for my 5.1 speakers since my new system doesnt support my old one. The options I was looking into were

Creative Sound Blaster Audigy FX PCIe 5.1 Sound Card
ASUS Xonar DGX PCI-E GX2.5 Audio Engine Sound Card
Creative Labs SB0880 PCI Express Sound Blaster X-Fi Titanium Sound Card
Creative Sound Blaster Recon3D THX PCIE Sound Card SB1350

Almost simirar prices. I will use it mainly for music and movies. So which of these will be the best?

System Model HP Compaq 8000 Elite CMT PC
System Type x64-based PC
Processor Intel(R) Core(TM)2 Quad CPU Q9400 @ 2.66GHz, 2667 Mhz, 4 Core(s), 4 Logical Processor(s)
