Is it even possible? Also I'm being a cheap skate obviously... Just not ready to buy my other 7770HD.

I don't think that this can be done in a reasonable way and even if it could, your computer would not be able to do DX11 gaming because the 4850 isn't DX11 compatible. This should be doable on a computer if you get a motherboard with a HydraLogix 200 chip and maybe one of a few other chips, but those are rare and usually expensive boards.

You'd need something like this:

No, you can't do that. AMD CrossfireX Technology requires two or more similar GPU's and the 4850 is much older technology than the 7770. You can only crossfire a 7750 or a 7770 card with another 7770.

crossfire only works if the first 2 digits of the model match. the crossfire will take on the clock of the weaker card. I.e you can xfire a 6870 and a 6850, but the 6870 will downclock itself.





cards below this is almost irrelevent

Hey, man, what if he got a HydraLogix board? He could totally rock the two together. Joking aside, CrossFire isn't supported cross series(HD5xxx and HD6xxx, for example).

That's what I was referring to.

Do you find HydraLogix funny? It can pair two of ANY graphics cards so long as one of them has an NF200 chip or the motherboard has an NF200 chip. Heck, you could pair a GTX 295 and a Radeon 6970 or some other wacky combination that way if you wanted to. The motherboard link that I gave has one such chip.
