Here goes: I feel like I'm slowly outgrowing my 12" 1.33 ghz Powerbook. Currently my issue is with WoW on it. While playing WoW I get like 15 FPS in cities and sometimes my character just outright stops. Initially I thought it was lag but then when I turned on the FPS display it definitely showed a huge drop (and my latency is usually 48 ms). And when I've viewed it on my roommate's MBP (same wireless connection etc.) there's like little to no 'lag' in response or stuttering. I was wondering if there was something like an 'external graphics card' or something that could improve my performance. Thoughts appreciated.
