Single GPU eqivilent of Crossfire 7950's?

I recently got a computer with crossfire 7950's and I've been in driver hell ever since.

After weeks of troubleshooting and constant testing I've decided crossfire is not worth the trouble. Can I get a recommendation on any SINGLE gpu cards with a equivalent (or close enough) performance to crossfire 7950's?

Not only would the card name be appreciated, but also the brand of the card (like gigabyte, sapphire). AMD and Nvida cards are both welcome.

the closest would be a gtx 690
but due to availablity issues i recommend the gtx 680 or hd 7970 ghz (when available)

Like he said the closest card performance wise is another Dual GPU Card :D .You really cant get that much performance from one GPU.

If youre going to overclock you should take a look at these two

If you want the best performance without overclocking this HD 7970 is the way to go :)

Even if you go with the overclocked HD 7970 Vortex you will get only 75% of the FPS the HD 7950's give you.

While I understand the frustration, I would suggest waiting it out a bit. Drivers will improve (I hope).

I have crossfire 6970s and was in the same boat as you. My system was built specifically for BF3 and I experienced nothing but frustration with the beta and then a few weeks of the full game. I was considering scrapping the whole setup and doing as you are contemplating.

Sure enough, waited a few weeks, drivers matured, and my system ran most games flawlessly. If I encountered any issues, it was generally in older games that weren't as graphically demanding. Crossfire could be disabled accordingly with settings still on high.

Being that the 7950 is almost top of the line for ATI right now, there are no cards that will even come close to matching a crossfire 7950 setup (when its working). As panwala pointed out, the GTX 690 will be the closest you can find, its basically a 2 x GTX 680 SLi setup in a single unit for $1000 if you can find it.

Short of that, get a 7970 and overclock the piss out of it, but it will not be close to the full performance potential of your 7950 xfire.

Perhaps you can explain the problems you are having with crossfire. I don't believe many others are experiencing many issues. Is it a specific game that has issues, or all and what is the rest of your system, monitor included.

What kind of driver issues are you actually suffering? It could be something to do with your computer or how you installed the drivers themselves... You won't get that performance out of a single GPU and I find it hard to believe that the issues are that sever this far after release.

This was the thread I posted.

Try disabling ULPS. It's enabled by default when you install CCC, and my 7970 crossfire setup doesn't work at all when ULPS is enabled.

As to your question, you can't get a single GPU that's anywhere near as fast as 7950s in crossfire. The 690 is a single card but dual GPU, and is still likely to run into problems with some games (although Nvidia seems to have their dual-GPU act together with drivers more than AMD).

I recommend what I'm doing - just troubleshoot as best you can and wait until the next generation or two comes out when you can trade in your two cards for a single card that performs similarly but without the problems.

What exactly is this ULPS?

Sorry I've only recently entered the whole custom computer scheme.

How do I disable it?
July 24, 2012 3:41:55 PM

ULPS is a power saving mode for the graphics cards (I think it just enables the second card to enter a lower-than-normal idle power state when idle)

You can take a look at this thread (which I have not tried):
http://www.overclock.net/t/667144/crossfire-disabling-u...

or you can download ATIman uninstaller, which has a disable ULPS function (separate from the main driver uninstall program which I don't necessarily recommend if you don't know what you're doing):

Ok i've just disabled ULPS and so far everything seems to be going swimmingly (although my GPU drivers have chosen to work for more then 15 minutes beforehand)

I'll get back to you guys on this.

Yes definitely make sure you have the CAP profiles installed as well (although I'm fairly sure that the problem you are having was being caused by ULPS).

CAP profiles?

Oh and one more question, will ULPS be off forever (like if I restart the computer, will it not automatically turn off)
July 24, 2012 4:51:24 PM

CAP profiles are small files that help programs preform better when using crossfire. if you follow the link i posted above and look at the third item on the list it is 12.7 CAP1 which is the profiles for crossfire.

^^ yup... CAP profiles, when installed, improve crossfire (and occasionally even single-GPU) performance

ULPS will remain off until you install a new driver version, as far as I am aware.

motherboard ?
CPU ?
PSU ?
OS ?

and before all else try an new bridge cause it is cheap, test using friends if you need to.

There is nothing at all worth spending money on if you already have 2 7950's

Since you are having problems at boot up, this sounds like either a power, bios or hardware issue. The drivers play no part during the boot up process.

Is there going to be a 7990? if there is you could wait for that or get a 680 or 690.
