Hey guys I am just getting back into gaming again after a long hiatus. I have a decent comp.. its a dell xps 720..

2.4ghz quad core, 8800 gtx vid card, 4gb ram (only recognizes 3).

Anyways.. I plan on upgrading...

I plan on getting case, ram, mobo and processor at the same time and then video card at a different time.. These times will be atleast a month apart so I'm wondering where I will see the best increase? New video card first or get the new mobo/processor/ram first?
