Hello,


I have a dilemma about my graphics card. I have ATI Radeon HD 5670 Sapphire 512 MB GDDR5 and I tried playing Battlefield 3 but the video settings are automatically set to low/medium. I was thinking about buying another HD 5670 card and using Crossfire X since that is the cheapest way to improve my PC.
Since I don't have any expirience with CrossfireX could you please tell me how did it work for you with these cards and what performance improvements can I expect? Also is my CPU/PSU/motherboard good enough?


My system:

OS: Windows 7 64 bit

Motherboard: Asus P5E

Processor: Core 2 Quad Q6600 2.4GHz

Memory: 6 GB

PSU: Asus model A-55GA (550W)


Thank you in advance for you answers and suggestions.

Uninstall the ATI/AMD driver package and let it re-boot. Then shut down and install the 2nd card. Boot up. Install the latest drivers for your cards. Be sure the Crossfire box is checked in the CCC/Performance tab. You will see an improvement in gaming at 1680x1050. But the 512MB memory will still be your weak spot.
Or, you could sell that card on ebay and put the money towards a single HD 6850 1GB and play at max/near max settings.

I did some research and I think I'm gonna go for 6850 as you suggested. I hope my PSU will be able to power it. Maybe I should overclock my CPU as well.
Last question, which HD 6850 should I get (was thinking the ASUS one) and what about nVidia gtx 460 or some 5xx?

Thanks for replies.

That HD 6850 will be perfect for that resolution. You will be gaming at max settings in any game.

I bought the same PowerColor card you guys linked, and I'm impressed with it. I agree with the others, don't bother with CF 5670's, go with the 6850.

One other thing. If you have a board that does Xfire @ x16 x4, don't waste your money on a second card. My 2nd machine has one of those boards, and I tried 2 HD 6850s in Xfire. It actually slowed my framerate in some games and only made a slight improvement in others.
I have a x16 x16 Gigabyte board in my main machine and it almost doubles my framerate from a single card in every game I've tried so far.

I'll keep that in mind. I'm probably gonna buy an entirely new PC in a year so I'm just hoping to be able to run games smoothly until then. I'll have my new card in a few days, can't wait :)
