I can tell you that I'm pretty happy with my crossfire setup.

Honestly, Im more bias to single card solutions.
as crossfire/sli
dont have good scaling all the time, they work great in some game but dont in others. say crysis 2 it just terrible.
even in bfbc2 it only has about 50% increass.

so i would recommand wither gtx580 or the hd6970 which are both great cards and amazing value. they will for sure run bf3 at max 1080p.

I had two AMD 6870's for about 25 days. I did experience microstutter every now and again. The reason I switched however was completely a different reason, I wanted to go 3D Vision on a single 1920x1080p 120Hz monitor. Made the switch to a single GTX 580. Same performance really on par. No hassel however.

For $180 x2 = $360 or one for $460.00 is a difference. Up to you if the extra money is worth it to you. Either choice is going to give you good gaming.

If you can't afford the one GTX 580 up front then you don't have a lot of choice and go with the one AMD 6870 now. Crossfire it later down the road. You may have to turn down some game settings on the more intensive graphical games but you'll get by until you crossfire.

That's my

Well I'm in a situation which is very similar to you, I'm upgrading within this month too for battlefield 3 & I have a GTX 460 & I'm getting the ASUS P8P67 Pro, i5 2500k, 8GB G.Skill Ripjaws, a 750w CM PSU & a H70/80/100 all in a phantom case So i was thinking about getting another 460 & go SLI but it's not worth it for me due to Vram cuz I'll be gaming at high resolution so i decided to get a single GTX 580 & maybe SLI in the future when price cuts down.

I was in the same boat as you. I opted to sell my 5870 to the bit coin miners on eBay and went with a msi gtx 580 lightning. The performance increases a oveclocked 580 can achieve are impressive, that's why I spent extra on the msi which has great cooling and I hope to reach 950mhz+. My other option was a 6950 cfx set up. I didn't go with the 6950s because of increased heat, noise, power consumption, and driver / crossfire profile issues. The 6950s in cfx do beat a gtx 580 in benchmarks, but the gtx 580 should ne able to play bf3 just fine and I have an upgrade path to do sli in the future. Or if you are patient wait for 7000 series.

I have a 6870 xfire with 6850 both OC'd to 950/1100 no problem so far. But still a single powerful card still the best offer if you can afford it or maybe sell your 6850 then add more cash to get 580.

More like $280 and no it's not worth it. Cheapest option would be to go with another HD6850 but if you really wanna sell it and upgrade to something more powerful then imo the 470, 560TI and 570 are much better bang for buck investments.

My patience will probably depend on how well I can BF3 when it's out. If the 7000 series has a clear release date by that point, I'll probably wait for it. If there's still next to no information, I'll end up going for the CF as a cheap stopgap solution.

Hopefully they will release the "casual" and high-end cards near the same time. I'd be fine with dropping a large chunk of cash on a card that will last me a while.

Yeah I'm not sure how I did my math there. I'm not sure where I would even go about selling my 6850. If end up getting a 2nd one, I will definitely try and sell them after I replace them.

Okay I'll put in my $.02.

Given the fact that the next gen is coming fairly soon, and you already have a 6850, and presumably you're gaming at 1080p or below ... I would probably choose another 6850 (note: NOT a 6870 - I don't think you'll see enough benefit to justify the extra dough it costs in this scenario) for crossfire.

The net cost to you, even assuming you would sell your 6850 if you got a 580, is MUCH lower ... and you're talking about very similar performance between 580 and xfire 6850's, at least at 1080p resolution.

People like to bring up the 'support' for multi-gpu a lot, and I suppose it's a valid point, but MOST games that you're likely to want to play WILL have multi-gpu support. I mean, if you're one of those people that HAS to play every game the day it comes out, or likes to participate in Beta's for new games that aren't out yet ... you may experience frustration from time to time because sometimes the drivers don't get the multi-gpu profiles added until after a game is released.

USUALLY though if it's a 'big' title, the profiles will be in the driver before the game is released. And there's work-arounds if they're not. For example I just fired up the 'Pirates of Black Cove' demo, which came out yesterday. A pretty obscure game, just came out, so ... No SLI love.

So I went to the website of Paradox Interactive and looked up the other games they make, and found a popular one called "Mount and Blade".

So I fired up nV inspector, and checked the available game profiles in the current driver set, and discovered M&B DID have an SLI profile. So ... guessing that perhaps this new game shared the same engine as M&B, I added the .exe of PoBC to the list of games for which the M&B SLI profile would be applied.

Et Viola ... the SLI works perfectly now. If I'd known the name of the .exe for Mount and Blade, I could've just changed the name of the PoBC .exe to match that of M&B, and it would've worked just the same, but I didn't, so I took the more complex route of using nV inspector. The whole process took all of 5 minutes, tops, and I had my SLI support.

Is that a 'headache'? I suppose it could be called that. Does it really bother me, personally? No. It's just a challenge to be met And BTW ... the SLI scaling is phenomenal on this game. It's close to 100%. Maxed out, the game was unplayable w/o SLI. FPS between 20 and 30. Once I fixed SLI, it's been holding real close to 60fps the majority of the time, the lowest dip I've seen is 48fps. Obviously, it's become totally playable now.
