Nice card. If you forget to connect the aux power cable the card still fires up and displays a message reminding you to connect it.
PCI express 2.0 is backward compatible both ways: a 1.0 PCI card will work in a 2.0 slot and a 2.o card will work in a 1.0 slot. Your new card should work fine in your PC.
p.s. USASUCKS is not a very nice name.
Thank you for letting me know information about the PCI Express 2.0 X16 video card in a PCI express X16 slot.
I have another question for you...How much power does a video card use.. (Watts)
This one says you need a 450 watt power supply , note that I have an 500 watt power supply 85% eff.
I know my name is not very nice but I am in Asia....
Just being goofy
