Does going AMD complicate things for Xfire or any major features lacking?

post #1 of 11
Thread Starter 
I m building my wife a new rig and a partial LAN box for myself. I m considering AMD as she just doesn't need to be bleeding edge.

Would I be hurting myself if I want to Xfire two 7950s or anything along those lines?

What should I know in order to select the best hardware for an AMD system?

I ve heard the 8320 is just a downclocked 8350...is this true?

Any recommendations on solid motherboards?

The only real problem is that there aren't any enthusiast matx boards

8320 performs the same as 8350 at the same clocks.

I m using a HAF XB for her case so I m not to worried about that.

I really doubt you would experience any problems. The difference between AMD and Intel as far as CPU and GPU combos go is negligible when talking about the same range of performance.

Only thing you might find different is drivers. And also, crossfire 7950s ? What exactly sort of performance are you trying to get out of this ? (ie, resolution you're playing at, etc.)

I run crossfire 7850s and it outperforms a single 7950 and 7970 in FPS in just about every popular game. I game at 1080p and get 60 FPS in just about every single game I play, Crysis being the exception. This is with settings completely maxed and v-sync on as I hate screen tearing.

As far as using a m-ATX board, I just ordered my mother a new build using a m-ATX board and paired it with an Athlon II X4 640 and 8GB of DDR3 1066. Honestly overkill, as she only browses the net and runs programs like word and excel, but should last a very long time as far as her needs go. Plus I have a spare HD 4830 sitting around that I'm going to through in the build just to avoid using the onboard graphics. And another bonus is my old power supply I just stopped using fit in her case fine.

The problem with m-ATX as LuckySe7ens mentioned is there isn't really any high end boards available as far as AMD goes. Crossfire is possible, but you're definitely going to be cramped for space on the board. Low profile RAM is definitely recommended. Also, I looked at the case you're using. In the build I did for my mom, I went with a m-ATX case, Rosewill Ranger-M mini tower. I WAS going to get a Hyper 212 plus just for some extra CPU cooling but knew it wouldn't fit. So keep in mind how much space you're working with.

Crossfire=headaches IME.
What will she be doing that requires 2 GPUs?

This is my lan box as well and I am more than likely going to get her a 2560x1440 monitor (same thing I use).

Micro/mini isn't a big deal since that case supports regular ATX and has the capacity to cool what I want.

Definitely subjective. I installed a second 7850 a few weeks ago and haven't had a single problem while gaming or performance issues. No stuttering or anything.

Ok, good on the case. As far as the resolution, going with the 7950s is more understandable.

I personally think crossfire isn't really full of problems anymore like people for some reason still want to believe. I'm running the most recent beta drivers and have zero problems. Only issues I have are my first GPU running hot when overclocking high.

I m just trying to make sure I m not in for in unforseen headaches due to my lack of knowledge with AMD. I d like to prepare for Steamroller and it seems like a farm more economical choice that isn't quite as dead end as the Intel sockets right now.

This is the board I m looking at:

http://www.asus.com/Motherboards/SABERTOOTH_990FXGEN3_R20/


P.S. I know two 7950s are overkill for 1080p. I m just making sure I don't decide I want 2 of them and find out AMD sucks a fat one when it comes to Xfire and I should've researched more. If it is all comparable on that front then I am happy to move forward. Right now it seems the CPU is only thing questionable and that depends on what I m doing. For her purposes it will fly regardless. I m going to use the 8320 as a stop gap until Steamroller comes out and just upgrade her to that.

Well take it from me, my crossfire 7850 setup get's a score of 56 FPS in the valley benchmark on the extreme preset.

Ill probably just snag one to start and then go from there. Right now she is just at 1080p so the money may be better spent on the monitor. I m using a 7970 on my I7 920 and she is no slouch except in Crysis 3
