Sadly, you're pretty much cooked. With no discrete graphics card expansion slot, the best you can do is add a standard PCI graphics card. Because the bandwidth of the PCI slot is so limited, though, you won't get satisfactory performance in yesterday's games, let alone down the road. This performance bottleneck is also why PCI 3D cards typically come only with lower-end graphics chips. PCI video cards aren't totally worthless. They can provide additional video inputs and outputs, and they can also improve overall system performance because they typically have their own graphics memory, freeing up system memory that would otherwise be shared with an integrated graphics chip (such as the Intel Graphics Media Accelerator 900 chip on your eMachines T5062's motherboard). Unfortunately, the best way to upgrade your video in this case is probably by buying a PC with the appropriate slots.
