2 x PCIe 2.0 x16 (dual x16, blue)
1 x PCIe 2.0 x16 (x4 mode, white)
1 x PCIe x1
2 x PCI
The top blue PCIe 2.0 can't be use since I have a SB sound card in the PCIe slot. I'm pretty sure I can add the other card to the PCIe 2.0 x16 (x4 mode, white) but I don't know if I'll get any improvement or gain from it.
I also thought about picking up another sound card for the PCI slot, but it seem like there aren't any good sound card compare to what I have that will work. I'm running a creative SB X-Fi titanium card in the PCIe slot.
What would you guys do? Any recommendation would be great!
