The TFII's cannot unlock at all, TFIII have a chance
That was my fingers failing to hit the same key three times in a row. My bad. >.>
The TFII's cannot unlock at all, TFIII have a chance
6950 ===> unlock it takes 5 minutes if that====>1gb model is 204.99 and 2 gb is 249.99====> i like how you talk to me like i dont know anything...esp when i have the hardware that i talk about....bud

not gonna argue with the decision, 580 is a good choice, but just to clear up some "myths"
Constant updating of drivers: AMD is on a monthly release cycle. This is no less frequent than nVidia. I really don't see your problem here.
New to the AMD drivers: not really sure what you mean. But I'm guess it is that you have never used CCC or something? I mean for the 1 minute you will use it in your life, it works fine. I personally think it is more organized than NCP, others think the other way.
Crossfire issues- most games support it some don't, most get it patched in by updated CAP packages. Valid point on your part though, single card eliminates this.
Microstutter- really hard to notice unless you are getting consistently low frame rates, CFX has come a long way since X1800, for the most part microstutter is un-noticeable. Again though, single card has 0% microstutter.
Unknown overclocking routine: google it? It is literally the same as nvidia now that nvidia linked the shader and core clock like AMD. you move a slider, raise volts stress test.
Just to clairify I have 2 systems one with 2x6950's bios unlocked (With a gtx 260 for physx) and one with 6990+6970 tri fire and the micro stuttering is 100% able to be eliminated.
By running the game at a setting where your graphics cards are able to output more than the monitors refresh rate (that is, the maximum FPS the monitors are capable of; the pixels on your screen can only change so fast) microstuttering is eliminated completely. Most monitors have a refresh rate of 60 or 70Hz, meaning you would need 70 or 80 FPS to eliminate microstuttering. Also, running the game in Split Frame Rendering (SFR), with the top half being rendered by one card and the bottom half being rendered by the other, will eliminate microstuttering, but opens the door to tearing and a performance hit. I don't know if SFR is even still supported...
Micro stutter has been around as long as 2x GPU's were possible and the truth it all you have to do is top fps OVER what your hertz is on your monitor and its fixed or force SFR mode. Most people don't know this or like to base their opinions on people that would rather complain then fix the problem.
I would never drop money on the toxic or frozor cards as they are too close to the pricing of a 6970 which at that point i would just fork over the extra 60 dollars total to have a much better stable OC with the cards without as much wattage usage.
As item # N82E16814127588 which is frozor does NOT unlock at all most people RMA them to receive tier 1 released cards that do unlock, doubt you want to do that.
item#N82E16814127562 DOES unlock but it is a 50/50 chance there and it costs 289.99 up front. If you RMA these you will not receive tier 1's
These two above are all MSI, now onto the toxic's sad and true the toxic lines DO unlock but your chances are less than 10% that they do with NO chance of RMA, they use the antillies chip which is physically disabled on the card to not being able to unlock the bios. You might get lucky with good stock but i doubt it.
Best way to catch how the stock is doing is;
1.Call them (if they think there gonna get a sell more or less they'll help you)
2.Check review DATES that model will have to been changed to the antillies chip due to AMD's instructions.
3.Have good ties into the industry.
But aside from that your mind is made up and I don't blame you just trying to help you along your way. Now before I get a trashing (haha) ill throw some good things your way
Evga is an amazing company with a step-up program and a good warranty
With nvidia you'll be able to use physx which is a nice plus but ehh
Going with one card opens you up for SLI later if you need to upgrade [The reason why a lot of people push for the 6950 crossfire is even without the bios unlock your only gonna be 10-20 fps ( with the unlock its a whole nother story) slower then 580 SLI at 1/2 the cost]
In the end I take the time to write this not to be a jerk but to help you and maybe somebody else something they may have passed over some things while building a computer. It's your money you do what you want with it! :biggrin:
I hope this helps more for anybody who's reading.
PS: I prefer nvidia but they dropped the ball this series
TIP: Take that ram and downclock the speeds under 2000mhz and lower latency as DDR3 has diminishing returns after 2000mhz if not used in a tri-channel setup.
Get 1600 ram and a single 6950 now, then upgrade when 7000 and 600 series released. BOOM.
Noticeably faster? In what scenario? Benchmarks? And a 3 slot 580 is not a great investment at this time.
even then they cant get a decent kit past 1600. idk if you are into that thing, but that is why i keep my 2000MHz 8-8-8-24 kit around. I have some pedestrian 1600 CL9 kit i use for everyday use, but the fast kit lets me easily beat out people running processors that are even slower than mine.
