#1. The celeron is not enough processor (solo core) and 1 gb of ram is not enough ram to run vista properly and add salt to your wound, the x3100 may not be enough graphic card to do you any good.
#2. At least this one has a dual-core (preferred to run vista) but still on the short side of ram and even worse graphics.
For college I would recommend anything that has a Intel Core 2 duo processor, 2 or more gb of ram and an Nvida 8000 (or higher) series graphic card. The down side is that you will have to double (or more) your price. Remember, you cannot up-grade your graphic card on a laptop like you can on most current generation desktop computers.
I don't know much about hardware/specs n all but could could someone tell me which one of thses would suit me, i need one for college and WoW - thx
