I want to upgrade my graphics card from a EVGA 9600 GT KO to a Gigabyte GeForce GTX 550 Ti 970MHz 1GB PCI-Express HDMI (OverClocked). My questions are this, my computer is a shuttle SX38P2 Pro which only supports PCIE- X16 version 1.00. The power unit is 450w so that is adequate and it has the nessesary 6 pin power. The new card is PCIE 2.00 so will it work okay in my system and what performance reduction do you get using a PCIE 2.00 device in a PCIE 1.00 socket? I have since starting to look at replacing my current card the EVGA 9600 is also a PCIE 2.00 device and it has worked fine for the last 4 years but could not say if it has been hampered or not by the PCIE 1.00 slot.
My system has 8 gig Corsair TWIN2X4096-6400C5DHX - Corsair ) DDR2 PC2-6400 800MHz
