Crossfire HD 5850 or Single Card Upgrade

post #1 of 10
Thread Starter 
I am considering pulling a HD 5850 out of an existing PC that I no longer game on and replacing my GTX 275 in my PC with a crossfire HD 5850 setup.

Should I chose the HD 5850 crossfire setup or just buy a single card?

My concerns are I have never done SLI or Xfire so not sure if there are drawbacks to this vs having one card. I really dont want this to be a pain, would rather just buy a single card if its easier unless I am saving substantial money.

One last question What single card most closely compares to a HD 5850 in crossfire?


PS. Cost to do crossfire HD 5850 is a total of $280 (210 for another 5850 and $70 for the replacement card going into the PC that I no longer game on.)

Not sure where you live, but Open Box ASUS 5850 for $160 here. Personally, I'd go with 5850 crossfire, but I am biased.

What games do you play? They might not be crossfire-friendly games. If you need help searching, just post up which ones you play and we'd be happy to help you out.

I mostly play Wow and Star Craft 2, but will be playing Dragon Age 2 and future PC games. Also I have a 1920 x 1080 monitor. From bench marks it looks like a CF 5850 will be good, but I don’t understand what caveats there are when setting up Crossfire?

Well a single 5850 at stock clocks is roughly a 4850X2 card....When it is OCed it competes with 5870 fairly well...

So without the loss of SLI/CF scaling..a CFed 5850s will be 2 4850X2 cards at stock...OCed it will nearly be 2 5870 cards...

I hope that gives you a idea...

Unlike Nvidia...you can crossfire gpus in the same series... for example you can crossfire your 5850 with a 5830,5850,5870 or 5970(essentially two downclocked 5870s on a single pcb), without having to be the same clocks or GPU retailer...

Is there an advantage to using a better card in a crossfire or does the better card take the lower cards specs when crossfired?

What will happen if you were to CF a 5870 with your 5850 is this...your 5850 will work at 100% load(if the game is that demanding) while your 5870 may only be a 90-95% load...As the 5870 has more muscle to it...

If you are thinking of getting a 5870 to CF with...I say do it!!...Use the 5870 as your main GPU, so that when you come across a game that doesnt use SLI/Crossfire, the stronger card will be running it....But this all depends on what you want and your budget, of course

I think i will just stick with the hd 5850.

I have a XFX 5850 which is OK... Would I be best off to buy the same exact model of the HD 5850 I already have or go with a different brand that is getting better reviews (Asus)?

Just seems I may be in a better spot if I have the same exact brand and model. or does this not make one bit of different?

I would rather get the asus card because its cheaper and better reviews, but will spend the extra cash easily to have LESS issues.

I decided to just leave my hd 5850 in my htpc and order a gtx 570 for my main gaming PC. The whole micro stuttering issues with crossfire and sli make it not worth the hassle.
