What resolution is the monitor? For gaming the graphics card is the most important and its hard to know how much to put into the graphics without knowing what you need it to run

There's a start

Then you are going to need to sacrifice on some components or get a bigger budget, the OS throws a wrench in the works as it eats up a large chunk of the budget. You can save 43 by dropping to a dual core

You can also get it down to about 40 euro cost for the case by getting this one instead

But really a full build with higher prices for only 700 USD is not going to make a good gaming rig, if they offered combos you might stand a chance but its a small budget to fit a build with an OS into, you will likely need to drop back a generation of processors to the AM2+ ones.

I can fit this into my budget i know there is not much ram but i can upgrade that when i get more money i dont mind a boring case. i know the power is a bit cheapy but it should work. I was thinking should i go with xp and upgrade to 7 later on instead of going vista and then going to 7. and i dont need over 320GB of space coz all i do is gaming and i can always get a nother one later on if i some how fill it up.

I think its a good budget system i have the same budget but i droped back to am2 so i could get a better graphic card

IS vista home basic that bad??
