Is it possible? When I was putting together my new system about 6 months ago I decided to go with the 5770 because of its price point in hopes of later on adding another and CrossFireing them together. Now I have the money to buy the second card and I can probably afford the small difference in upgrading to the 5830 series which has Eyefinity (an option I wouldn't mind having for my next upgrade) or possibly a 5850 if my bonus is as much as I'm hoping. I just want to make sure that you can indeed Crossfire a 5770 series with a 58xx series before I spend the money. Thanks for any input that can be given.

Agreed with Psycho, only an HD5750 and HD5770 are crossfire-able.

However, an HD5770 crossfire is very potent, especially if you overclock both of them.

Best option is either get a second 5770 or sell the one you have and get the 5850 !! (figure if you can get $100 - $120 for your 5770 then an extra $180 - $200 will get one of the several $300 5850's for only a small amount more than a second 5770 would cost you.

OK, thanks for the info. I was actually afraid of this, but coming from the nVidia side of the house originally I was hoping Crossfire ran the same way that SLI was capable of, that being you could SLI to different series together. Of course you did't get the same power as two of the same cards, but it was something. I guess ATi didn't enable this type of option for their cards. I'll have to mill this around some and figure which way I want to go. Thanks again. :)

Didn't think to ask in my initial post, but what is the best way to OC a video card? OCing a CPU is easy enough to understand, though I've never tried it myself, but I'm not familiar with OCing a video card. Thanks.

It's very easy; you should have a program called Catalyst Control Center. Open that, and navigate to ATI OVERDRIVE. From there, click the 'unlock' key, and start overclocking.

Well for simple overclocking it's just fine. It has profiles, etc.
