Hello there.
I'm trying to build a very nice PC, and I'm in a bit of a conundrum.
Should I get a regular PC configuration, with one video card, the Radeon HD 5850 (which, supposedly, is better than even the nVidia GTX 465, even though the 465 is listed higher at videocardbenchmark.net), or get a Crossfire type of configuration, with two Radeon HD 5770s (that would cost a bit more) or with two 5750s (that would cost exactly as much as the 5850)? (Money is a bit of a factor, too.)
I understand that:
5850 - has core clock of 725 MHz, 1 GB of memory, and 256-bit memory interface
5770 - has core clock of 850 MHz, 1 GB of memory, and 128-bit memory interface
5750 - has core clock of 700 MHz, 1 GB of memory, and 128-bit memory interface, but also 2-DVI, unlike the 5770.
It would be very nice to have 2 GB of video memory, and two GPUs working in tandem, but I'm still not sure whether it's an upgrade over just the one, better video card. Is it?
I also am not 100% sure what kind of motherboard I should get for the Crossfire option, if I decide to go with that. (But I know I wouldn't like to pay more than 150 dollars for just the mobo. And it has to be able of full HDMI, of course; otherwise what's the point, right?)
Oh, and having two GPUs... would that need some extra cooling in the computer case, too, in addition to what I would need for just one video card?
Could the expert(s) who are kind enough to reply also, please, support the argument with a little bit of extra proof or insight? Thank you very, very much.|||ok first yes a single card is quieter. and i suppose easier (plug 1 card in instead of two)
but in terms of performance i have no idea what this guy is talking about.
two 5770's can outperform a 5850. and is most cases a 5870 as well
take a look at these benchmarks.

as for the cooling yes crossfire runs a bit hotter than s single card. you can just buy a 8$ side fan for your case and that should keep them good enough. 5770's are made to run hot and are fine up to 90C.
also no the scaling for Ati Crossfire is not bad. it used to be bad with the older drivers but with the newer drivers its become very good.
5770's cost around 150$.(newegg.com) so a pair would cost 300$ while yes thats a bit more than a 465 or a 5850 if they can outperform a 5870 then im sure they can outperform a 465 by miles.
also dont worry about weather the game will support crossfire or not. the only games that dont are REALLY old games (like 90's and early 2000's) which the requirements are so low that they dont even require dual 5770's
all modern games support crossfire and Sli.
as for the motherboard im sure you can easily find one under 150$ i got my Msi790xt-g45 for 90$ on newegg. full crossfire support. just look around on newegg for a board that supports your parts. good luck and have fun!|||okay start like this
nvidias GTX 460 is same/faster then a 5850
so a 465 is better
as for dual graphic cards
first of all ATI cards (crossfire) scale alot worse then nvidia cards (SLI) it does work ofc (i got dual 4890's in CrossfireX) but not even close to as good as nvidia graphic cards in SLI
5770 can mby be faster then a 5850 IF the game is very well made for SLI/crossfire, thats the problem ,it wont work on all games and ushally aint painless to get it to work either.
if you have 2 GPU's well extra cooling aint much to do, depends on what mobo you get, i got mine very close (just 3mm space :S) my cards run at 60-70C (top card) and 45-55C (lower card)
thu i do have a fan on the side of my case that helps :D donno how much thu
to make it easy
singel card is easier and probably more quiet
465 > 5850 (not arrow, its a mouth, always points to the bigger/better one)
5850 > 5770x2
anything > 5750
