Hi, I want to upgrade my 2x ati radeon HD 4800 series graphics cards. They have crossfire enabled. I've read an earlier thread recommending the radeon hd 6850 series card as an upgrade. My question is, will I need 2x 6850 cards?

Thanks for the answer danzas4321,
Sorry for sounding stupid but I'm not very good with computers. Will the single 6850 be better performance than 2x 4800s, or is 1x 4800 only running at a time? Would appreciate an explanation why there's 2x 4800 installed in my pc.
Thanks

the 2x 4800 are in crossfire. Crossfire is AMd's way of making two cards work together on one task. So in games instead of one GPu processing all of the frames you now have two cards working to produce the same output. the scaling isnt 100% perfect so you wont egt 200% Performance increase but there is one. Back in its time those 2 4800's would have wrecked everything out, now due to technological advancement not so much :p  i believe the 6850 will be faster than the 2x 4800's. whats your budget for a GPU?? Also the 4800's dont supports DX11 so some games are no longer supported

Thanks so much for the explanation, much appreciated. I always thought I'd have to replace both gpu's and it would end up expensive. My budget is around £130 seen as though I'll only need 1 gpu ;)  . My pc is a Dell XPS 625, Amd phenom 2 x4 940 processor, Am2+ socket, 8GB ddr2 ram, I'm sure the gpu's are the 4850 version PCIe express

4850x2 is better than a 6850. The only game that is dx11 only is crysis 3 so any other dx game is supported. At that budget though you'd be looking at the r9 270 which will be a decent amount better. http://www.ebuyer.com/614458-powercolor-r9-270-2gb-gddr...

Thanks for that. The reason why I want to change the gpu's is because I play world of warcraft and over the past 2 months when I start playing the game, the gpu's go very noisy until I exit the game then they go quiet again, so I'm guessing either 1 of the gpu's or both are on the verge of giving up because I've had the pc for about 6 years now

They could just be dusty if they weren't loud before. Have you cleaned out the pc?

I take it to work about every 6 months and give it a good blow out with compressed air (being careful of course). I've had it repaired recently because the cmos battery holder came away from the motherboard and was causing bsod and the shop cleaned the pc then.
It only seems to go very noisy when I play world of warcraft recently, the noise has usually been normal with that game. As soon as I go into gameplay the noise whirls up as if 1 of the gpu's fan powers up but is noisy lol

Honestly, I would never ever ever recommend 2 GPUs in a single tower unless you are very good with computers, or work for geek squad your self, or have incredible cooling inside your tower. The fact that they are getting louder means the fans are spinning faster, if the fans are spinning faster, they are getting hotter. GPUs that are X-fired always have 1 cards HOT exhaust blowing right on top of the other card. Besides, those are old cards that run on "Legacy" AMD drivers, and don't support DX11. I recommend finding a better, single GPU. I currently have a single ATI Radeon HD 4800 in my rig, but then again, im running a i-7 quad core overclocked at 4.8MHZ and liquid cooled. My computer runs better off my CPUs built in GPU. I run World of Warcraft daily on the card, with settings on full ultra, and it runs about 60-100 frames per second. I have an external temp. and fan controller however, and running WoW causes the fans to kick into hyper-active mode. This seems and sounds bad, except for the fact that faster spinning fans means cooler graphics card. I recommend shopping for a single, yet better graphics card. Honestly anything with at least 1GB of ram on the card will handle running WoW on ultra, while also juggling lol.
