  1. And does it change the performance ?
    Ram 1 gb
    Cpu : 2.9 ghz
    Os : Windows 7 ultimate
    Motherboard: MSI K9A2GM V3
  2. The 7770 is said to work fine with the PCI-E 1.1. Look at this thread and see for yourself what the first answer says:

    and about the performance difference,not much difference can be seen. There'll be a slight difference of a few fps,just like you see when adding a PCI-E 3.0 card to a 2.0 slot. So you should be fine.
    But seeing that you have just 1 GB of RAM and a CPU,whose model and manufacturer you haven't specified,I suppose the 7770 will be bottlenecked by your PC,and don't blame the 1.0 slot for that please... :)
