Building my first computer

[Xigmatek]

Hey all.
Am new to all this computing.
So i thought it was time to follow my brother in computers Ive got about a grand to spend, probably a little bit more.
Worked very hard to get this money and would like some advice on a graphic card to go with my system.
Ive been given my brothers old monitor a 24 inc as his upgraded to a hdtv.
Dave said if i waited till Jan i can have his old 4870x2. But just been bought the new need for speed shift for the pc.

Is this a good combo of parts for a gaming rig. Thats all i would be doing on it. but mabe my bro can show me some overclocking when he gets back from overseas. Army and all..
Thought about having a go on bros pc, but it looks really complicated. with all them pipes and all. he running two cards from what i can see but on one lead coming out the back. Whats that all about. am also going to buy a pc mag(Any good ones out there?). so i can start learning about this kinda stuff.

I have about a grand. but could use some of the money i have for holiday about another 200.

With the card its not costing me anything. as the 5850 will cost me 70. As hard as it is i might buy all my other components. first then have his ati. how long would that card be ok running games before i have to start lowering graphic spec in games down?
