Hey guys.
I recently bought a new screen that is 3D capable. However I probably need to upgrade my graphics card in order to use the 3D properly. I currently have a Radeon HD4770. With a 550 watt power supply. I was thinkin about getting a Radeon HD7770 and then using the two in CrossfireX. Would this work? or would I need to upgrade my PSU? I'm aiming to get about 72 fps for the 3D to work effectively. Mostly I play racing games. Such as dirt 3. Currently I'm getting 36 fps at ultra settings and 1920x1080. AA and stuff such as that are not that important to me. Your advice would be much appreciated!

What's your total system specs?
And no, you can't run HD 4770 with HD 7770 in CF, and if you have a quality branded PSU you'll be able to run something more powerful than HD 7770.

Depending on your system specs (CPU, RAM, PSU,.........) i'll give you my opinion.

The new 7000 series are very power efficient. I think you can probably run 7770 in crossfire with a 550 PSU specially if it's one of the top dogs(corsair or antec.stuff like that)

You COULD run in crossfire, just not with a 4770 :D

The rest of the system is a core i5 2500processor(the four cores at 3.3 ghz)
Asus p8p67 evo mobo
And 8gb corsair ram at 1600 mhz
The psu im afraid is just a normal huntkey PSU.
@ilysaml why would i nt be able to run them in CF?

for you to realize any significant gains in crossfire, the two video cards should be the the same model, otherwise the slower card will bottle neck the more powerful card. :cry: 
I'd also recommend a better PSU if you DO crossfire. Something from Corsair, XFX, Seasonic, Antec, PCP&C, or Enermax.

Great system you have but;
That PSU is not a quality branded one and it won't deliver the written wattage on it, but it will run the HD 7770 just fine without any problems.

You can only CF 2 cards from the same Series...such as HD 6870 with HD 6850 or HD 6970 with HD 6950 but you can't CF HD 6850 with HD 5850 or HD 4850.

I see you have a strong and nice CPU, and gaming on 1080P with a good eyecandy and in 3D mode!! requires a high end graphics card so at least i recommend HD 7850 if your budget allows or you can step up to a HD 7870.

They won't even run in CF mode, and if you mean a HD 6970 with HD 6950 for example, it's just simple as you'll bump up the Core and Memory Clock to the ones that match the HD 6970. But it's always high recommended to git the exact same card when doing a CF/SLI Configuration.

It's always Recommended to get a high end GPU instead of two mid range GPUs, you might have problems with CF scaling, drivers problems and Microstuttering. So a single high end GPU is much preferred. I still recommend the HD 7870.

If you didn't buy the CPU make the move to the i5 2500K version.

Of Course. It's almost as powerful as GTX 580.

Would it be enough to go with the HD7850? or do I definitely need to upgrade to the 7870 if at all possible?

GTX 680>>HD 7970>>HD 7950>>GTX 580>>HD 7870>>HD 6970>>HD 7850

Performance in order.

You can still probably get 72 fps on dirt 3 with a 7850. Just search benchmarks on the internet they're everywhere

If you plan to play in 3D, I think you'd be pushing it to expect 72fps with an HD7850.....

haha no you misunderstand. I mean 72 fps when I'm gaming without 3D. That would mean I get at least 36fps with 3D on. The reason I said 72fps is because most benchmarks are for normal gaming when 3D isn't activated. :)
