I tried waving the UPS driver down but he was off like a flash...right at the end of my drive way...10 seconds too late.

I took pictures of everything as it sat on the steps and called UPS and the Egg. UPS was not much help but NewEgg was! (box didnt even have the packing or invoice inside)! NewEgg said to try everything and see if it functions properly...if not then just return it for RMA and they will cover the shipping! Not too bad lets just keep our fingers crossed!

QUESTION: Since this is a NEW build from scratch, when I get to install everything....how will the graphics card "know" to talk to the monitor? Since there is nothing on the HDD's yet and its all in pieces...sorry for the newbish question but this is my first build from scratch.

Now its time to start building!!!!!

You will not be able to use Crossfire [your dual GPUs] if you are using more than 2 of the DVI ports. Don't ask why, it just doesn't work haha.

What a lowly score i had on vantage:



Anyway,tomorrow i'll overclock the system and run it on a fresh vista.




Hey,and about only showing half memory,looks like it does the same to everyone,right?

Try to OC your CPU to 4ghz if you can but don't OC the card. Set CCC to "Balanced". You should get around 9,000-10,000 points. But then again, this card is slightly different, it has lower clocks also at stock than the 2GB.

Really nice pic! Love the green tubing. Has this card given you any issues yet, if you have tested it? I know alot of people with DFI motherboards are having issues with X2 cards. Let us know, if that's the case for you. Post the benchmarks that I have on the original post for your results. Thanks in advance.

Wait really that one of the reasons I bought the 4850 X2. O well probably never end up getting a second card for xfire anyways.

Let me redirect you to one of my previous posts: Click Here

To summarize: The HD4850X2 has two GPUs on the board, and in order to use both of them you must enable "CrossfireX" in ATI Catalyst otherwise you will be working with only half the power.

• You can use two monitors only with "CrossfireX" enabled.
  
  
• If you want to use 3 or 4 monitors, you have to disable "CrossfireX" and you will be working at half power.

I hope that clears things up for you. Don't confuse this with Quad CrossfireX (when you have two physical HD4850X2 cards connected to each other).

oo IC.

but according to Sapphire support it doesn't matter whether xfire is enabled or not in CCC since it is all done internally.

Edit: I just tried it with crossfire disabled with furmark (I used the exe that uses xfire) and it's only using 1 chip. I guess the idiots have no idea what they are talking about. Typical tech support

That is completely not the case apparently. I tried working with "CrossfireX" disabled and my FPS went way down so you can definitely tell thats not true. Whoever told you that has no clue what he or she is talking about. There are a lot of clueless people working for Tech Support.
