Hey Maziar, thanks for replying. Sorry, was enjoying the weekend
You're right, CPU-Z reported my card as the 9800M GT, not the 9800 GT. Intrigued, I decided to take the laptop to the shop where I bought it (asked them to open things up so I could look inside without voiding the warranty). Turns out it said "9800M GS" on the GPU itself.
I've also read around, and it seems this is a bug on CPU-Z. Oh well, we can always dream!
