It does not matter about the video ram. You can use DDR2, DDR3 or DDR5. More of a concern would be the PCIe 2.1 version being compatible on your 1.0 motherboard, but it should work. Some have had issues and others have not. Make sure you have the latest Bios version and chipset driver installed and you should be fine.
As Kelbear1 says, the video card RAM is independent of the system RAM. For example, my old Socket 939 (DDR 400) works very nicely with a 6450-based video card with GDDR3 memory.
The PCIe 2.0 cards are supposed to be backwardly compatible, although that's not always the case. Again, the old Socket 939 illustrates this well: it will not resume from S3 sleep mode with an older 5450-based card, but it does so just fine with a new one that's 6450-based.
