Windows 7: 1 GPU vs 2 GPUs

1 GPU vs 2 GPUs

In my gaming rig I have a GTX 660 but I also own two Radeon HD 7870 cards, now my question is fairly simple would the two Radeon cards win in performance over my GTX card or should stick with only one card?

Plus in a not so far distant future I am planning on buying the LG's 34" UltraWide monitor.

Uh hope the title is good, was a bit unsure what to put there!

Well the 2 GPUs in theory would be faster then one, however its completely dependent upon the games you play. Sadly Crossfire is far more broken then SLI at this time.

.... ermmm depends , there are several editions of the 660 , some are super powerful , same goes to the 7870 , but be aware that ati use alot of power even when its idle , so if u dont have to worry about the power consumption , compare the ram bus , core clock , ram clock or basically run a game and compare fps between the 660 and one or both 7870 and pick the way it gives u better fps

I think a single 660 is better than a single 7870, but 2 7870's will beat a 660. But, it depends on what game you are playing. Some games are not optimized for SLI or CFX, so with 2 7870's, you would actually be playing that game with one 7870. So, it's a decision you would have to make depending on your games and not knowing about the newer games coming out.

I'd sell all three and buy a single better GPU personally.

Actually, the single AMD card technically will perform better then your GTX card..


GTX660 Vs HD7870


I think the Xfire is something like | Base stats + 40% | at the moment with current drivers.

The 660 and 7870 are very close in performance, you could see 15% either card depending on what game is loaded. Straight up specs I think the 7870 has a slight edge. Crossfire can be problematic, when running at it's best you could see a 50% improvement over a single card. Some games can only use a single card.

There are some good deals around on 280x and 290x, you could sell the 3 you have and upgrade.

Thanks for the responses, sorry that I have not said anything in a while, been busy with stuff. madcratebuilder, sure I could do that, though I will have to check the state of my 2 7870's because I have used both them for mining so I'm not sure what it has done to them.

depending on which game u want to play , i recommend nvidia , watch dogs has come to all of us , ATI performance on watch dogs wont be good imo , and my PC is on 24/7 so ati is a dead end since power consumption while idle is just too high

Sell all the cards and get one of the new Intel HD based motherboards coming out. From recent tests, they are comparable to a 660 as I recall. It's only going to be on the high-end boards but what did those cards cost you? And you won't need a Mega-Watt PS and case full of fans.
