Hello, I currently have in my case an ATI Radeon HD 4850 graphics card and I recently bought of ebay an ATI Radeon HD 4890 to go with it. But it doesn't fit in the mother board? Any help please?

I think that is the problem, that I only have one PCI express slot. The original card is slotted into something that is blue and is a bit bigger than the other slots
 
you have only one PCIe x16 slot, so you will be only able to use the HD 4850 or the HD 4890, you can't use them both together in crossfire as you don't have additional PCIe x16 slot
