[quote=&quot;Sauron&quot;]i'm stil lost with the video card. how much ram you recommend? 512? 1GB[/quote]
I've got an ATI x1950 XT, it's a 256MB DDR3 card and I think it plays the UT3 beta just fine even with all the quality settings turned up all the way - I don't like the look of the game that way though.  I've never let the amount of RAM on a card concern me much but the more the better.  Sometimes the big difference between something like an x1950 XT and an x1950 XTX is the amount of RAM but I don't know if that's often the case. The price will also be more - a 1950XTX with 512MB might be selling for nearly $400 while the 256MB 1950XT can be found for under $200.  How much do you have to spend?  I don't like to spend more than $150 on any single component for myself but that's me - I'm usually broke and have to scrimp and save forever to put together a new machine :)  512 would be an ideal minimum right now maybe if you can afford it.

Tom's Hardware actually has a recent roundup where they pick they're favorite cards for different price ranges here:

Months ago the ATI X2900 cards were poop, but new drivers have fixed that apparently and they chose the 2900 Pro for the $280 price range :)
[quote:16d651f6eb]The Radeon HD 2900 XT debuted with mediocre performance compared to the GeForce 8800 GTS 640, especially when price was factored in. But ATI has stepped up to bat and introduced fresh drivers that really bring out the 2900's potential, even allowing it to challenge the 8800 GTX in some arenas.[/quote:16d651f6eb]
But the nvidia 8800 series of cards is just better than anything right now... especially looking toward the future with DirectX 10 games.
