Damn forum errors. 
Reposting,
 
 @ repi You mentioned that the demo was powered by the GTX 580 card. SLI (2 or 3)? Debating on which GPU to settle on come fall.

@ themobsoftware only 1 geforce 580 card

Safe to assume a 580, coupled with a quadcore Possessor with 4-6GB of RAM would run this without issue. That being said, can we stop having the "ZOMG No one will be able to play without a SUPA COMPUTORZ!" I keep hearing on every website/podcast. You can build a rig that can play BF3 for less then the cost of your Macbooks, and would be more useful(Trolling not intended).

So I have a Geforce 280 - what would be a good card to upgrade to before BF3 comes out (Nvidia only, ATI has always caused troubles for me)

I don't understand why anyone would upgrade now considering BF3 isn't gonna be out until Q4 of this year. Save up your money for when the game actually comes out and you'll get a better system for a cheaper price.

There are other games coming out before BF3, so there is a reason to upgrade for some before the game hits.

Shame a GTX 580 costs nearly as much as a PS3 and 360 combined. 
 
I'm sure my GTX 460 will handle it nicely, but unless the console versions are complete pants, I'll most likely be picking it up on 360.

Cool, that'll save me a few hundred dollars in October or whenever I buy my new comp.

This was confirmed on the day it was shown. 

I'm sure my 5770 will run this on the second highest settings well.

I don't understand why everyone is thinking it will require such insane specs to run... Remember this game has to run on consoles people, so I'm sure it'll look good even if you haven't upgraded your GPU since 2007. (good as in same as consoles. I would hope.)

I'm sure DICE have already said that if you can run Bad Company 2, you will be able to run BF3.

Either a 560 Ti or 570 GTX if you want to stay Nvidia.  I actually got an EVGA GTX 470 as a warranty replacement for my 285 which died so I'd happily recommend that too (easly 25% faster than my 285 was) but of the other cards are even faster and cooler to boot. "

Nice source. "

Now I need to check if any new cards are coming out before bf3 comes out that make it worth waiting.

Nice being late to the party.  "

 I guess that's good news for people who want to upgrade, for me though I just hope my HD 5850 is up to the test when the game comes out :).

Ugh I need a new processor first. My GTX 260 is getting pretty old, but it still holds up pretty damn well. However a dual core........sigh.

I still don't see a source, so I imagine your full of shit. "

so when the game comes out i will see how my 5870 runs it, if I can't run it at the quality level I want I will get a new gpu, and sell my 5870 to a friend.

"@Geno:  Thanks for telling me the 1st time around. I searched and found nothing. Not to mention your post about it was an estimate, this is confirmation. Also seems like no one knew, so your welcome. "

I heard it was 2 580's running in SLI

MY 6870 should be good :)

Awesome, I'm building a PC soon and although I'm going a couple steps down from a 580, this means I should be able to play the game on medium settings smoothly at least (assuming that the graphical intensity doesn't get bumped up later, as this is pre-alpha footage and so there's probably less to render now than after more effects and textures get added in, etc.)
