Yes, but not much is know. Remember 5870s are still going for high prices. 5870s also in dual cards still run great and more than needed for maxing games, Later on use 6970 users can quadfire.

GPU: No one can, of course, say how demanding BF3 will be.
But as some of the others are suggesting, I would also recommend holding off until the next GPU series are being released. It will presumably make the current line of GPU's fall noticable.
I respect your non-Nvidia thing, but honestly, a GTX 460 or GTX 560 is not bad.
However, The HD 6850's in Crossfire should do you very well. It performs the same as my GTX 460's and I am able to play anything besides Metro 2033 on highest graphics (while Metro being terribly close) with decent FPS. I really doubt BF3 will overtake Metro 2033's throne. By all means.
When the Radeon HD 6850's in Crossfire are overclocked, they may perform on level with the GTX 580 in quite a few games.

PSU: If we assume you pick up 2x HD 6850, you will not need anymore than 550W at most.
Like the Antec EarthWatts EA650 and the Corsair TX650W V2 PSU. They are both very decent and durable (with the Corsair being modular), so I would recommend those for your needs. They're not that expensive.
However, for Crossfire/SLi, four 6-pin connectors would be preferred, though they are no must. These only have two each.

2GB concern: At 1080p, 1GB will be enough. My GTX 460's only struggle with Metro 2033 because they lack memory, while they are actually fast enough to play the game at max settings. And Metro 2033 is the only game I have had the memory issue (damn you, MSAA).

CPU bottleneck: A PII x3 will presumably bottleneck your GPU's if you choose the 6850's (that setup is just an example to give you a slight heading about memory, speed and bottleneck). Perhaps about 10-30%.
A PII x4 will do far better when overclocked, a hexacore Phenom will honestly not make any noticable difference in games, since any game, as far as I know, only utilizes 4 cores maximum. Check out bencies, eventually.

A Phenom II x4 clocked to 3,8GHz will presumably only bottleneck your GPU around 2-10%, while an Intel i5-2500 will bottleneck it about 2-5%. All depending on the game, of course. Games like StarCraft II are very CPU intensive, and makes your framerates go down by 10-15 FPS when using a PII x4, compared to a i5-2500K.

So unless you're doing something CPU heavy like video editing or large image rendering, I wouldn't recommend an AMD Phenom II x6 at all.

My suggestion would be to wait at least a month to see what happends to be out there.
AMD's new CPU line, Bulldozer, is on our doorstep and arriving in june, as far as I know. Perhaps it will suit you better than any enthusiast CPU on the current market.

To speculate requirements for an unreleased game is complicate, like so many have said already. Best choice, keep saving money and wait for requirement spec sheet or final release. Because you may not need to ruin your credit with a 590/6990. I'm all for heavy hitting top end computer equipment, but from a financial standpoint it doesn't make sense to drop $600 bucks on a card that will be crushed by a 200 dollar part in 6 months

I recommend trying another chip to find one that will either be quad, or unlock to quad, plus a nice cooler to push it to 3.8GHz or more.
Then add a 6970 with over 1GB of video memory, and power it with a SeaSonic x650 or Corsair AX/HX/TXv2, Antec HCG/HCP/TPN, Silverstone Strider+/gold or similar quality power supply. A 650 or 750w quality unit will have the power to run a pair of AMD GPUs with ease.

You *may* be able to get good frame rates with the tri-core, but only if you can wind up the clock speeds to a decent (3.8Ghz+) clock speed.

Skip the 6950, even with the unlock it's not able to match the 6970.

Well it'll honestly depend what the market looks like but I'd much rather get a 69xx with plan to CF it later.

As for Unlocking my CPU I'm starting to wonder if I may have been premature in my assumtions. I haven't OC it yet but so far With +12% it's survived mild stress tests. I'm a little confused as to exactly what ACC is and google just turns up people as confused as I am. I'm gonna try to to scale this back and see what minimum stability for it is before I start to overclock it but so far it's promising.

I'd like to pick a PSU with a future 2x69xx in mind even if it'll be far down the road. If I can make this CPU juggle that board with minimal sacrifices then I can nab a mobo, bulldozer and another 6970 sometime next year when they're a little less bran spankin new.

The problem I have with 68xx is that they dont come in 2Gb. The way I see it, Upgrading is about achieving for4ward compatability as long as possible. Eventually this whole rig will be rebuilt by a series of slow replacements and I'll be able to have a whole second computer!

So today I'll be disassembling the thing to reorient my heatsink because I think it's losing airflow having been oriented to the old power supply which had a bottom intake. Even with a bottom intake power supply i think the rear facing exhaust will be better with my newish case fans.

I don't think I'll need a new heatsink until I get a new CPU. This one seems to handle anything I toss at it so far and I've never seem temps above 41C in any burning I've done but I haven't pushed the voltage yet either. (Well the one test I did that got 3.95 was with 1.55v in SmartOC)

If im losing %10 off the top of a 6950 then I don't see the need to get a 6970. 2Gb & the ability to crossfire with a future 6970 puts me where I want to be for $100 less.

Some things about BF3 aren't speculation. Like an independent thread/core for audio, utilization of up to 8 threads/cores. GPU reqs are speculative at best at this point which is why I've been dismissive of anyone projecting prophecy about their premature purchases. (lawl)

I don't play anything currently on the market and don't really plan to. BF3 will pretty much be my only game next to Alice which won't be nearly as demanding (Nor FPS count critical as it isn't a MP-FPS).

Things are looking promising and I should know within a day or two if my CPU is just teasing me or not.

at 1920x1080 resolution 1GB of memory on a video card is fairly enough. 2GB is for higher resolutions and eyefinity. It is best to upgrade for the future, so 2GB is wiser. But you also have to factor in price and what you are willing to pay.

I still say wait till the end of summer then decide where your going to put your money. Buying now for both those games that arn't even released yet isn't the smartest idea. if you wanted to play games now that would be different. But you already mentioned your only going to play those. The 7xxx series will be out in the summer as they've already started mass producing them.

If your going to buy anything, the first thing would be a psu. They never really drop in price. The one you linked in the thread earlier is great and will last you many builds from now on.

I would personally go with a GTX 560. However, since you prefer AMD/ATI, I would suggest getting the HD 5870/HD 6950 2GB. Also, attempt to unlock your CPU to 4 cores if you can. Your CPU will be your only bottleneck with cards like those.

Yes, as these are the only game I will be playing and price is a significant factor I do plan on waiting and hoping for drops. I will have to disconnect my computer from my 560w UPC but I have other uses for that thing but it's not really something I can avoid. Maybe I'll be able to get another one for this rig if the prices drop enough. (ugh, every time i think about this upgrade mroe expenses pile up LOL). PSU will be upgraded as soon as I can.

Still wondering if that PSU would support a bulldozer & two 69xx in crossfire. I'm having trouble finding out what the math is on PSU reqs for CF.

Hmm....looking at this one now: http://www.newegg.com/Product/Produc...82E16817152043

I forget, is a 6970 near a 580 in performance? If so, an OCed 6970 would do nicely. Just make sure to have lotsa Vram.
