I keep on saying that it wouldn't be enough to handle all your hardware. Just make the test I did, with a multimeter or a Magnetic amp meter (Is a ring that you place around the power cable of your PSU).

Mine is Sapphire. Box did not include those adapters.

Are you happy with your 512mb 4870's in CF ? Did you experience a big boost in performance ?

I was reading a review at tomshardware which was titled something like "4870x2 Four Cards Compared." There was lots of high end graphics cards in that review including set ups like tri sli's and 4870x2's in CF. And when I looked at the overall performance chart 512mb 4870's in CF was at third place between all these monsters ! I said wow i should go cf immediately

But do you think this is the real deal as you have a chance to experience it in real life right now. Would be happy to have your thoughts about it

I upgraded in August, so I was doubtfull between a single GTX280, or 2 4870 in CF (remember that the price was the same at this moment, 450€). I read tons of reviews, and I thought... Why not? Let's give them a try... And I am very happy with my decision. I didn't do many tests with a standalone 4870, but if you read some reviews, you can check that CF performs about 30 - 70% more than a standalone card.

I like playing games smoothly, and I wanted a "big" difference between my old 8800GTS G92, so I went crossfire. In august, 4870X2 wasn't released yet...

Today, with a single card is enough to enjoy all games (except crysis ), but the second card makes the difference. And... ATI 4870 would be at the 200 - 230$ before the year ends, so I think that when it's price go down, you must buy the second card.
