xfire r9 280x's

Go to solution Solved by don_svetlio,

7970 for 120$ is unbeatable in terms of price:performance.

As for heat, if you get a reference 7970 you won't have issues. Those usually ran at about 74*C.

Your i5 is fine

so recently my back up system has been more useful then my main system. dead new mother board (third mother board change in 2 months). 

my back up system is an i5 2500k at 4.6ghz under liquid with an asus mobo ( cant remember the model) matx board and a r9 280x asus dcu2.

 

i have 3 questions.

 

want to know about bottlenecking. i really doubt that an i5 2500k will be a severe bottleneck. i didnt observe it with a single 970. if it is i can clock it to 4.8 pretty easy.

 

i want to know about heat. i know the 280x/ 7970 (what ever is cheeper) is a hot card and in a matx system with no gap between will i experiance thermal issues? the botom card should have plenty of air room but the top card will be restricted.

 

lastly i would like to know if its worth it. if i can get a 7970 for around 120$ used. i have a 120hz 1440p monitor that i love and would like to continue to use while my main system is trying to ruin my wallet.

 

 

thank you very much.

 

my case is a phanteks enthoo evolv matx. 

 

another option would to buy a cheep atx case so the cards have breathing room. but i really love my evolv cases.

There are those that have good luck with crossfire, and those like myself that have had horrible luck with crossfire.

I say it's not worth it. Sell what you have and get a better single card, no one has had bad luck doing that.

If anyone asks you never saw me.

True, my meaning was problems not shared by both.

Crossfire is good for the ego, not the wallet. It's the least efficient way to get performance possible.

While I do like a single card, I currently wish I had bought a 270X 4G Vapor-X and Crossfired rather than buying Asus >.<

It would have been a LOT smarter. Good cooler, no noise, no iffy VRMs, no iffy Thermaltake PSU that I replaced later. I am stupid for trying to stretch to the cheapest 280 rather than buying a decent 270X and CFing later....

Live and learn. I've done worse. I've got 60 bucks in junk case fans I can't use because they started rattling a month after I got them. But they light up...

Use some WD40 - likely a dry bearing. Happened with one of my case fans.

i would disagree. especially with used cards. like used r9 290s even if cossfire does not work your still getting an amazing experiance and when it does work it is giving you preformance better then a gtx 980ti for around 500$. cross fire is great when it works. but sometimes it doesnt it all depends on what kinds of games you play.

The issue is price to performance, two 290/390 cost the same as a 980ti. The 980ti is more reliable, generates half the heat, and uses half the power.

but for alot of people dropping 600-700$ on a gpu isnt worth it. and if your game supports xfire or sli then ur getting better p2p. 

 

its all about context. i run sli and i am an advocate for it but only 8f xy and z condtions are met.
