You won't find a laptop that can read Wii/GC disks, as only certain desktop drives can.
As for a good laptop, you'll need to raise your price range a lot, to like $1000 minimum for a good gaming laptop with a dedicated graphics card with a separate heatsink for the CPU and GPU.
As for that laptop you have now, it is an Ultra Low-Voltage (ULV) CPU, so it is designed to not draw a lot of energy and not have a lot of power. Lightweight games will maybe run fine, but not many games will reach fullspeed.
