They are both die shrunk G92's but i think the only way one could remotely do it would be to flash them both to 9800GTX+'s, but i would not recommend it, incase there are other side effects.Agreed,although both are based on G92 architecture but you can't SLI them because they have to be the same model,however there are some ways which aren't recommended like flashing them both as "nuke" said or the method that "randomizer' said,these ways aren't recommended since they are risky

If you read the first page you will find your answer there
"Do the cards have to be same model?
I answer it with an example:
You have a NVIDIA Geforce 7800GTX 256, and you want to add another card , the second card has to be 7800GTX exactly."
So you need two exact cards to run the in mutiGPU configuration.

Well, I'm glad I read through all this! I'm building a new system and due to $ I had to buy the Diamond Multimedia 4670PE31GDTSB Radeon HD 4670 1GB GDDR3 PCI Express 2.0 Video Card. I have a xf system so from what I understand here..if I want to install a 2nd card it has to be another Radeon HD 4670 with the same clock/ram speeds. Also a quick question...is the higher the number of the card series the better cards (re Radeon) for example is the 5700 series better than the 4600 series etc. Next month I'll be either replacing the 4670 card with a higher end card or just buy another 4670 so I was wondering which was the smarter choice.
P.S. The link to the chart on 1st post doesnt work

Well about the numbers,its not always like that i mean for example HD 5700 series performs lower than HD 4800 series so you have to look for benchmarks,however in this case HD 5770 is faster than HD 4670,about the link,it's strange because it works for me,here is the original link:
http://ati.amd.com/technology/crossfire/charts.html.
Tomshardware wrote a review about 5770 and 5750 and it compares them with 4770 and 2 4770s in CrossFire mode:

I would start with the Toms graphics charts

Its a bit outdated sometimes(it takes time to test all new cards), but should be updated often enough to give you an idea. It also helps you to see what games do and do not take advantage of SLI/Xfire.
You can also google reviews all over the web with detailed info for certain games.

ya Nukemaster is right thats a good way to look things up keep in mind that there is a new generation of vid cards that is much faster ever 6 months to 1 year at most so buying crossfire or SLI systems is not really that great of an idea since the whole system will be out done in 1-2 years by a single card

Could you clarify/update this section. This is not accurate for AMD cards now as you can do mixed crossfire (ex: 4850+4870). Not sure about SLI.

Thanks for the great information. I am a novice and I just built a i7 920, 3-sli, but only have one 9800 gtx video card for now, and I was having trouble adjusting the graphics on the game. Other graphics looks great, but when I try to play cov or coh, the graphics looked really rough....choppy like. Any suggestions on how to fix this issue will greatly be appreciated.

If by choppy you mean rough on the edges as opposed to choppy bad FPS, read on
In COH/COV make sure AA is on, that game looks extremely jaggy without it. COH/COV is more cpu dependent then anything so, AA should not hit you too hard.
You will have to enable advanced settings(Menu->Options->Graphics and Sound, enable Advanced Graphics settings). Also, the bloom effects can hide some of the rough edges.
If you think you have a fps issue, in the chat bar type /showfps 1 and you can see your fps(top right) and make adjustments and see how they work(always leave the menu to test, it oddly enough can effect fps as does the WW/BM screens). Sometimes Vsync causes big hits in fps on this game(sudden drops). But with it off you get page tearing. So test it out. Also remember certain times fps drops are not avoidable. Invasions are one of those times.
I do not think COH/COV will get a boost from SLI/Xfire
Hope this helps, have fun.
EDIT, Also enable triple buffering for COH/COV in the Nvidia control panel.

Thank you so much Nuke
I didn't really need to build one with this spec, but my husband do alot of video editing so I figured if I'm going to build one, I might as well build a decent one.
Anyway, it was a pretty simple fix. He went to Nvidia site and update the driver (even though windows says everything was up to date) and that seemed to fix the issue

Windows doesn't say anything about the VGA,if you don't install the VGA driver from Nvidia/ATI site,windows automatically installs a display driver for you which is a basic driver just to show your graphic card is showing images.
So you have to install the latest driver from Nvidia/ATI site,glad your problem is fixed now
