Thanks a lot for yor welcome and the link to Phils computer Lab! It is running!!
After a short "ups", because the Screen was black for at least 30 seconds with no Video Input. Basicly the performance does not matter, I use the Card in my "Disc-Computer" where I have the KV2-Lite Mainboard (ECS K8T800-A) with an AMD64 X2-4200+ that has only AGP, but supports two Floppies 360k and 1.2MB - a third 1.44MB is connected via USB with SCSI, SATA and SAS Cards with WinXP and Win7 in parallel.
I needed a Card with Dual-Link DVI Connection (the Monitor needs Dual Link for the 2.5k Resolution), driver for WinXP and Win7, and only one Slot because I have - a 50pin SCSI Card for very old drives - it is functional with my 20MB SCSI drives, a 68pin SCSI Card for modern SCSI drives - even 80pin 146GB drives are working with an adapter, but not a very old one, a SATA Controller for SATA II drives - the onboard SATA Controller has the issue that SATAII drives will not work, a 1Gbit LAN Card and a SAS Card (with PCI to PCIe). So all Slots are occupied.
I had a GF7600LE in before, but this Card had a 1.5 Slot design and I hat to swap a PCI card when needed. Win7 is only needed with drives above 2TB and for the SAS card.
