I have this as the processor on my laptop and want to get an upgrade. I dont want to spend a lot of money around $100 if possible but i could spend more if nessary. I want to be able to play games like dragon age on low settings so hopefully the upgrade doesnt need to be expensive

It's usually not possible/extremely hard to change a CPU in a laptop. What are the specs of the laptop?

CPU speed 2.10 ghz
Ram 2.7 gb
OS Vista
Video Card Geforce 8200mg
Video ram 1.4 GB
Hardware T&L yes
Pixel shader 4.0
Vertex shader version 4.0

If i cant play games like dragon age on my laptop how much would a replacement that can cost me?
