Dual Radeon 6970's or Single 7970?

Well, it's almost the time of year where I go back to University (GO BLUE!) and get a nice tuition refund because I take slightly more in loans then tuition costs. I'm looking at using that money to upgrade my gaming rig (It will also be used for video editing for a class, so I can kinda justify it).

My current rig is -

Intel Core i5 2500K OC'd to 4.4GHz with Corsair H80 Water Cooler (I probably could go higher, but I'm slightly paranoid)

ASUS Sabertooth Motherboard, Socket LGA 1155, P67 Chipset.

16GB G.Skill RipjawsX DDR3-1866

XFX Radeon HD 6970 2GB OC'd to 1GHz Core Clock, 1450MHz Memory.

2X 300GB WD Velociraptors in RAID 0

1TB WD Black HDD

850W Cooler Master Silent Pro

Thermaltake Armor V.3 (I'll be upgrading to a XIGMATEK Elysium later on. I've seen it in my local PC shop and read reviews. The thing is huge and has great airflow.)

My question is this, should I just purchase a second XFX Radeon HD 6970 and run it in CrossFire, since it looks like 6970's scale very well, and spend the left over cash on an SSD to use as a Boot Drive. Or should I upgrade to a single 7970, sell my 6970, and save up to buy a second 7970 (Probably will be able to purchase it late november, early december), however I wouldn't get an SSD to use as a boot drive. Will Microstuttering be a big issue? Or should I even consider getting GeForce GTX 670 (Or GTX 680), and then later on buying a second for SLI since my motherboard does support both CrossFire and SLI?

Also what are peoples recommendations for which Radeon HD 7970 (I'm looking at the MSI Radeon HD 7970 Lightning, however for AMD cards I really like both Sapphire and XFX, as neither company has given me any issues with their products, I've had 2 Sapphire cards and 3 XFX cards) or GeForce GTX 670 (I am very partial to EVGA cards, as I've own 5 and never had one issue with them, although I am open to ASUS since I've had 4 ASUS motherboards and they haven't had any issues either).

Can anyone also give a good recommendation for USB WiFi adapter? I can't reach the router in my new digs.

What's the performance difference between dual 6970's and single 7970?

So the 2 6970's blow past a single 7970. But for the price, I could maybe sell my 6970 (Street price around $300) and grab two 7950's and that might be the best solution? Or maybe invest in a single GTX670, and try to get another one down the road?

I'm not really worried about running a crossfire setup on my 850W unit, it's more then enough. I think I might get a 7950 GHz Edition and then in a couple of weeks get a second one.

I think it'll be fine. Besides, I found my answer, theres a local guy selling an XFX Radeon HD 6970 for $120. I can transfer the warranty and just run dual 6970's.

I doubt I'll have a microstutter problem, my 4850's ran together just fine. Does anyone see anything wrong with this plan?

7950 CFX is not a bad suggestion....
They will out gun a single 7970 no problem, but again, we hit the old problem... microstutter and driver misbehaviour, the 7970 will save alot of future headaches.

micro stuttering was only seen on the HD 68xx series ?

you'll be more than happy at that price,My crossfired 6950's run flawless! and I have never had microstutter on any of my crossfired setups(3870,4850,4870,5850,5870 and 6950's)

I thought microstuttering was more a HD 5xxx series issue? I've been browsing the forum and the only cases of 6970's microstuttering was due to a bad driver install.

Plus for a $120 I have way more performance then a single 7970. Plus it saves me like $330 to save for getting a 8xxx series card.

7970 for sure. Sell the 6970 while people are still paying a good price for them.

As for USB wireless adapters, I've used quite a few and this one, while being one of the cheapest I've used, performs the best and has lasted the longest of any I have ever used. The only downside is it's big, ugly, and white.

6970s rarely sell for $120 that aren't broken. I just sold 2 6950's for $180 each last month on ebay and it took about 10 hours. Which leads me to believe people saw that $180 as a good deal for a 6950. If you saw a 6970 for $120 then you should have bought it because it's probably gone.

6970's do microstutter quite badly:



LOL, that was fun to watch. Thanks for that Recon. I wonder who he complains to when he dies in multiplayer? I didn't see the stuttering. But IIRC 930 core clock isn't that high for a 6970 clock. I believe my 6950's ran 950 and that was just because I had one that didn't overclock as well as the other so I had to bring it down some.

But honestly, I've done CF-X. A few times. I'd rather just have a strong single GPU setup, that's just me though.

Either way both setups will provide good performance. One will have no stuttering issues at all, consume less power, run cooler/quieter, and be further upgraded in the future if the OP even deems it necessary.

Yes local deals are nice, I buy and sell on Craigslist all the time. I actually picked up an A8-3870K new in box for $50 today and just resold it on ebay for $80.

I like to use ebay to judge used prices because you can see several of the same item listed and get an understanding of what its worth. If he can get a 6970 for $120, thats good. I would still rather get a 7970.

I've read many times that 6970s and 6950s don't micro-stutter unless they go under 40ish fps but anything under the 6950s do... This is when I had my MSI 6970 lightning that I did all the reading.

Personally, another 6970 and a SSD... Then, sell both 6970s and get a 8000 series.

Honestly though, provided it is in good working condition I would buy that 6970 anyway and use it and resell it. Use it first, see if you fall victim to this "microstuttering" if you like it keep it. If you don't sell them both and pick up an $80 profit on the 6970.

ya here I just picked up for my Backup rig 2 OZC vertex 2 120G ssd's for 90$ for the pair.Also a 975 3.6G phenom quad for 60$,just missed out on a GTX560 Ti for 100$.

Good luck OP anyway you go!

I have 2 6950 2GB cards and run BF3 at a resolution of 5760x1080 and love it.
Now I did get some microstutter at first but what I found out was when I uninstalled the drivers I didn't realize that windows had installed an older driver in a different folder then where the drivers that I had put in. So took me a few hours to figure it out. Where the AMD drivers were were under local Disk and the ATI drivers that Windows had put were under Program Files (x86)/ ATI Technologies.

After I uninstalled those drivers My system runs great. I get no less then 48fps running a 5760x1080 resolution.

I would go with the 6970 xfire

I didn't really notice any stuttering in the vid, except for a few moments, but I might just be ignoring it. It's really hard to resist running dual 6970's in Xfire for only $120. Especially since I'm a huge bargain hunter ( read how I got my rig if you're interested, I find it to be a cool story http://www.tomshardware.com/forum/forum2.php?config=tom... )

I might just try the 6970's and if I find the stuttering is ticking me off, I can probably sell them as a matched pair for $400 I think. Plus this lets me get that SSD I've been eyeing for a little while.
