1 GTX 580 or 2 6950 ... For the 500 price range.

post #1 of 45
Thread Starter 
Ok guys, some input from you would be highly welcome

So, i've been checking and checking and with the latest updates on the unlocking of the 6950 i'm thinking about something.

For the price of 1 GTX580 i can get 2 6950's.
Ok, i will spend more money on the extra waterblock but, what do you think. Is it worth going xfire with the 2 6950's? ( who knows, maybe i can unlock them eheh )

It's in the same price range ( i can get 6950's for 250Eur ... )
I'll be gaming at 1920x1200.

Thanks in advance.
Pedro

well if you can get 2 6950s for 500... then yeah go with that... but the gtx580 is a better card and 1 card is usually more stable

2 6950s would be faster but you may get problems in some games which don't like CF. Generally it should be fine though.

I am sad to hear myself say this, but I say the 580's. People HATE Crossfire with ATI due to how many problems there are with the drivers.

Also when 580's drop in price you can get a second one then, and then dominate benchmarks and games...

And if you can still get the waterblock for higher overclocks

Ohh this thread is gonna get blown up!
lol.

Well, 6950's scale very well.
For $300 each, if you have the mobo, GPU and case/cooling for a SLi/CrossfireX setup it can be a great way to achieve Tier 9 performance without emptying the wallet.

There is all this recent news about unlocking 6950's and updating thier BIOS to 6970's but some people are saying they aren't made for it and its making the performance worse.

If you have good luck with AMD the 6950's are a great buy.
If you want a more solid single GPU solution, the GTX 580 simply cannot be touched.
And they overlock quite well.

Personally I ended up having one to many driver issues with AMD.
Which is too bad, because when it worked, it worked good.

2 6950 are very good even more so now considering the new news about them being able to unlock to 6970s. So yeah, if you can get 2 6950s for the price of one 580, get the 6950s.

Get one GTX580 and put a waterblock on it, and then overclock it.
When they drop in price, add a second.

I've been hearing (reading) about the 6950s bios flash unlocking to 6970 status. Doesn't that void your warranty? (and the artifacting that occurs when you push the flashed 6950...2 6pin connectors vs 6pin+8pin)

It's really just a matter of choice. I've owned ATI/AMD and nVidia cards. I liked what I saw at the time (the 580's performance) and went with them.

Now, I'm waiting to see what the 6990/595 will have in store.

Honestly I would get the 580, I have 2 6870s now and I'm trying to sell them. I thought every thing was fine until I went and tested my cards 1 at a time, thats when I noticed it. Stuttering, not game stopping stuttering but annoying as hell, focus on it more than the game stuttering. Its driving me absolutely insane, so just be prepared for it. I'm going back to a single card solution though just for the smoothness. I've been with Ati/Amd for the 5XXX'x and now 6XXX's and I'm gonna give nVidia a shot again.

Im not having issue's really with CFX other then overclocking stability.

If it is CFX related. i doubt it. iv'e had more issue's with SLI then anything.
But then again my current GPU's are tempermental in terms of overclocking. they seem stable. then lose it. i have to keep adjusting everything to get them stable.

1 GTX 580 is impressive. very powerful. no compatibility issue's. basically a dream for a average gamer. my second choice would be 2 Mid-Range Single Gpu card's in either SLI or CrossfireX. still stable due to games useing more then 1 GPU.

and i would advise against 3+ for gaming on a single monitor. use 3D or eyefinity for that sort of thing.

at 20$ cheaper my 6870's can beat ( only slightly ) a single GTX 580. but when the 2 are this close in term's of performance. if one can properly set up multi GPU's with driver's. setting's and stability. id'e say go for it. but 1 GPU is so much easier!!!! to manage and use.

my dual mid range graphics have been as smooth to me as a single GPU. but stil...
