-ATI Mobility Radeon HD 4650 - 1GB GDDR
-HDD: Seagate Momentus 7200rpm 500-GB Hard Drive 16mb cache
-Win7 x64

I need to choose between
-8 GB ram (both slots are full already) - $80
-ram and small SSD (for OS only) - $80 + $100ish
-large SSD for OS and prog files(120GB or so, i have a lot of necessary prog files) - $250ish

I use the laptop for school (Visual Studio, Office, web, adobe cs progs, etc) and games (SCII, COD, BFBC2, etc).
My boot time is bugging me, but i could also use less lag when multi-tasking and better performance in games.

The SSD is far more expensive so i only want to choose it if it will give a significantly larger boost.

Also, would installing all my prog files on an SSD change much? or would it make the most difference with the OS?

Please include your tech exp

Thank you.
