Which Graphics Card to get?

I am ordering a new PC, and would like some advice on which graphics card to choose. The three I am considering (can afford) are:
1GB Nvidia Geforce GTS 250
1GB ATI Radeon HD 4870
1GB ATI Radeon HD 4850X2

Which card will give me better performance on max settings on a demanding game like GTA IV.
The rest of the system is as follows:
AMD Phenom II x4 @ 3.00GHz
4GB Corsair DDR3 RAM
1TB HDD

4850*2
i think both then ati cards are better than the 250

gta4 is not that a demanding game gpu wise its more cpu dependant
(except it needs a whole lot of vram)

ive heard ,but not 100% sure that gta has some problems with *2 cards

Considering it's an AMD setup, I'd choose either of these two, but I'd lean towards the 4850x2 as it outperforms a single 4870.

Now for the bad news - You'll be able to get 'good' gameplay, but not at max settings for GTAIV

I was leaning towards the 4850x2 anyway, so I think I will get that one.
As for GTA IV, I dont really mind, I just picked it because I have heard its a demanding game.

One more thing, the total size of the 4850x2 is 2GB, right?

No, unfortunately it does not work that way.

How does it work then?

The memory is shared between the two GPUS.
