Hello!, I have an Asus P5G41T-M LX3 motherboard running a C2D e8200 @ 2.66ghz. I have a PCI express x16 slot in my mobo. I want to upgrade to a new graphics card. I'm planning to buy a Nvidia gtx 460. Will it be suitable for my mobo as I'm planning a final time upgrade for this mobo. So, which card should I buy that will enable me to take on hold for atleast 4-5 years as I will not be upgrading my computer for next 5 years or so.
