Welcome to Tom's Hardware...
Can you be more specific on the model of your Inno3d 1gb ddr2 video card? Your motherboard has a PCIe x16 slot, so should work with any current PCIe card (1.x or 2.x). I would suggest to download the lastest drivers for your GPU and see if that helps.
Also, what games are you planning, at what resolution and how are your temps??
