I have a dell sc 440 server with a PCIe x8, PCIe x4, PCIe x1, and PCI slot but NO PCIe x16 slot. Some say PCIe x8, and PCIe x4 are only for RAID and SCSI drives and will not even recognize a video card. I just need a card that is capable of 3D graphics, HD resolution and Direct X 9.0. Does one exist that will fit in any of these slots? I have searched and am totally confused what the truth is here.
