I have an AMD Radeon HD 7900 Series and was planning on getting another graphics card becuase some of the games I play are getting some frame rate drop since I like to run games on high settings and my motherboard can support another graphics card. Will getting a slightly more powerful  AMD Radeon increase graphics processing power by more than double? Or is in not worth it to have two graphics card?

If you plan to use crossfire (dual gpu's) be sure your card is crossfire compatible, be sure to have a crossfire cable, and finally try to stay with the same brand if possible.


In case you are met with a serious problem customer service will be more likely to help if you are using their products exclusively.

well, i think you should crossfire, getting a crossfire cable is pretty easy, and you should see some great performance upgrades. One thing though is that not all games support crossfire efficiently, and you MUST (it's not compulsory, but it avoids unecessary problems) use another gpu that's the same as your current one.

I've been told by multiple people that SLI/crossfire is a waste of money/resources. A lot of games have poor support for it and some games even crash because of it. You will even have to disable one of your cards for most games that are 5-10+ years old. You're better off investing in a single killer card than spending money to get more of what you already have.

but... crossfire looks cooler xd

The problem with that is that I want to sell my current graphics card, but no one what's a used graphics card...

Unless the price diference and warranty compensates...

I had no problem selling my AMD Radeon 6870 a few years ago and it was a few years used.

Oh dear. Don't use crossfire. Use SLI but no - don't.

But a better graphic card instead.

SLI / Crossfire has a terrible game support. Every game needs to be patched. AMD ( just recently! ) and NV do usually deliver special SLI/Crossfire driver patches/fixes to support it.

Buy it's just a waste of space, power consuption and nerves for more performance. and it's not like 2x 100% equals 200%. It's more likewise 150% but probably worse.

Crossfire / SLI is only for those super hardcore gamers, who have a passion behind this and/or a large pocket.
It's for those who want to play Crysis 3 on a Triple Monitor with NV 3D glasses on full epic 4K Graphics on over 60 frames per secound.

Buy a better card and sell your old one. - My friend is doing this successfull with AMD. He only has to spend around ~50-100€ every year for the latest GPU by selling his old one.

I already had personally Crossfire and Dual / Double GPU. Ok, it was two years but it was just horrible.
And the micro stuttering, oh you will regret this, especially if you are very easy influenced by stuttering.

Yep, crossfire sucks, especially when it's built-in to the laptop. I hate it when I have to connect to power for Ghosts (amazingly high optimal settings) and BF4 (lowest graphics, highest resolution) to work 60 fps 
Oh, and I don't have my old PC anymore, my new laptop just pretty much does it all and BF4 works on it even better than on my old PC which had a better gpu (nvidia geforce gtx 660, laptop has gtx 660m), better processor but less ram.

I've never heard of having crossfire built into a laptop - that seems overkill to me but cool that they somehow managed to do it lol.

I have crossfire on my laptop..... with Intel HD Graphics (HD Graphics? pffft, seems legit) and Nvidia GeForce GTX 660M.

Nvidia calls it SLI, AMD calls it crossfire. Sounds like you have SLI?

Also I cant imagine it helps performance noticeably to have the shitty intel hd integrated chip running with the gtx 660m

It doesn't. I think it's for energy saving purposes.

Ah. Well my laptop switches between the intel hd integrated and the 660M depending on what you're doing to save energy - but it doesn't use both at the same time. Are you sure your laptop uses them both at once?
