Hey Everyone,

First off, let me just make sure that it is possible to crossfire the R9 270X and the HD 7870, right?

Second, is cross-brand crossfire possible? The two brands would be Gigabyte and Diamond.

Only reason I was wondering was that the Gigabyte 270X is a better deal than the Diamond 270X, at least on newegg.

Not that I really need an upgrade anytime soon, I was just exploring my options for the future.

Thanks!

✔ Best Answer
Crossfire or SLi setups are generally a waste of money, but it's your money to waste. You'll most likely need to upgrade the PSU again; if you're still running that 600W Thermaltake, you'll probably be cutting it pretty close. Does it have enough 6-pin PCIe plugs or will you have to use adapters? And don't forget the poor case cooling that was discussed in another thread. a 2nd graphics card = more heat. See the following article & check the recommendation for HD 7870 in crossfire.

Yeah, I figured I'd have to upgrade my PSU to at least 750 Watt, my current power supply only has 2 6-pin connectors.

So, it is possible?

I agree with riider about crossfire being a waste. That said, I believe the cards must be from the same series. Brand shouldn't matter. See the FAQ link below.

If that article is correct, then you could use those listed cards in crossfire. Is it worth the cost to buy the second card and a new PSU?

Nah, I really wasn't planning on buying those anytime soon, just exploring my options.
