Yes i know that there are a lot of topics like this...
But i´ve recently came into some more money and i am planning to actualize my pc with new components
I have the others figured out but i don´t know what GPU to pick up
MY future rig
Case- Antec 300
MOBO- Asus corsiar formula III ( or a gygabte with crossfireX for the hd 4870 setup)
CPU- Amd phenom II 965 BE
Rams- OCZ gold ddr3 1333 mhz
PSU- Corsair 550 VX( or 650 TX for hd 4870 CF)
Monitor- Samsung syncmaster 940 NW(1440x900 the gpu or gpu´s are overkill for this res but i wan´t something to last at least 2 years)
What do you think ? hd 5850 or hd 4870 VApor-xCF( the hd 4870 Vapor-x CF is at 260 euros in my country , the exact same price as hd 5850 here )

The 4870's CF'd are going to offer you better performance right now as opposed to a single 5850. 4870 is slightly ahead of the new 5770 in most benches, and CF 5770's are better than a 5850. If you want DX11 for the future though and the ability to make another leap down the road, getting the 5850 and CFing it later is more future-proof.
December 31, 2009 2:53:25 PM

Yup altough i would have to buy a new PSU hd 5850 CF would be more future proof
What worries me most about the 4870 CF is the heat , hd 4870 vapor-x are HUGE
and cf 2 of them won´t give them space to bread , plus one hd 5850 has low temps and consumes less than even one single hd 4890
In the other hand the difference in perfomance between the 2 setups is about 20 % at the same price...
But with such a crappy monitor that has a 60HZ refresh rate in the resolution i play i woulnd´t see a bug difference
It´s a hard decision indeed...

1 4870 is overkill for that resolution, I think adding another or getting a 5850 is pointless.

If i were you i'd invest in a 1920 x 1080 or 1920 x 1200 res. monitor and buy a HD5850.
December 31, 2009 3:11:12 PM

In two years maybe even an HD 5850 won´t be overkill
With crysis 2 coming up maybe it won´t be an overkill too
For now it sure is but in the future it won´t be , i know and you probably knwo too that hardware evolves very rapidly every day and i have to think ahead if i want to keep up
That´s just my opinion...

ok well you'll buy what you want, all im saying is CF 4870's or a HD5850 @1440 x 900 is not using the graphics cards to their full potientual.

i think you'll notice a big improvement in graphics detail if you were to get a monitor with a res of 1920 x 1080 or above.

just my 2 pence. : )
December 31, 2009 3:51:00 PM

Ok thanks for your opinion , you make a valid point and i respect it but if i buy a HD monitor right now i won´t be able to build a computer in time for Easter or Summer vacations nad i need one built by then.
I have been gaming in SD for my whole life and i´m fine buying a card that even thought is a total overkill to my monitor but it will last me a lot of time.HD gamingwth maxed out details in a pc is very expensive and this build and this monitor is more than i´ve ever had so i´m fine with it :) 
So i think im going with 5850 plus crossfire mobo
Thanks a lot everyone :)

Cool, The HD5850 is a great card, uses alot less power than 2x4890's, less heat and will perform great!

I've ordered my 2nd one (ASUS HD5850), have to wait 2 weeks for it though lol. Have a good summer vacation : )

He is right. Your resolution is basically the same as 1280x1024. Crossfired HD4870s or an HD5850 is simply a HUGE waste of money for that resolution. That hardware changes so rapidly is precisely why you shouldn't pay for more than you currently need. A year from now there will be better cards than the HD5850, it will cost half of what it does now and yet it will still be as pointless for your resolution as ever. The most you should be considering is an HD5770 and that will be great for that resolution for a long, long time. The only reason to consider something better is if you are going to get a new monitor in the near future. Even then an HD5770 is a pretty decent card for much higher resolutions like 1920x1080 and if you find it lacking you could always get another for crossfire which will give you performance similar to an HD5870.

A high res. monitor maybe cheaper than you think

http://www.overclockers.co.uk/showproduct.php?prodid=MO...

Thats a decent monitor for the price, I know you've said what you want to do, but really a 5850 @ 1440 x 900 is a waste, it will be half asleep whilst playing games : /
December 31, 2009 4:16:55 PM

Hd 5770 is fine but won´t it bottleneck with my CPU?
should i pick up Vapor-x(140) or nromal(130)
And are ou sure it can play all th recent games including crysis with everithing maxed out(AA etc turned on) at at least 30 fps with this res?
Do you have low res benchs of this card?

"Bottlenecking" is about whether the cpu will limit the card and to answer that question your processor wont be bottlenecking. Basically with that processor and an HD5770 it's your monitor that will be limiting your gaming experience as that combo would be great for a 1680x1050 monitor and good for 1980x1080. Really that would be the best way to spend the kind of money you were talking about initially to get the best gaming experience; an HD5770 and a good 1680x1050 monitor.
December 31, 2009 4:58:56 PM

I know what bottlnecking is and it works both ways , that cpu is amd´s flagship Cpu and well hd 5770 is more of a mid end card i had to be sure there woulnd´t be any problems
I will see if i can save more money for a decent monitor , maybe a TFT with better image quality but as i said HD gaming is expensive on pcs and im used to low res.. Hell i used to play crysis with a 8400 GS and this exact same monitor and that was awsome to me , im not really a demanding person but you do make a good point and im going to try to buy a slightly better monitor in the near future

okini55 im sure he knows a 5850 is better than a 4870 >.<

You could do what i do, Get a 1080P TV and use it as a monitor aswell. Problem is TV's arent made to be PC monitors (even though it workd fine) and so suffer from high input lag and slower refresh rates.

You could always just buy the 5850 now and then in the future buy the monitor if you dnt have all the money now.
December 31, 2009 5:34:52 PM

lol i don´t even have the money for the hd 5850 right now
Only in about 3~4 months so i would take almost al least more 6~8 months form there to have an half decent monitor , so i would game for almost 1 year with a hd 5850 and my old monitor
I dont even have a HD Tv
The best solution would be to buy a hd 5770 , then a decent monitor and only then another in crossfire since CF 5770´s are still better than one single 5850
What do you think?
ps: btw how does CF work? if you have 2 cards connected with the bridge do you get signal just from one that is connected to your screen ? do you need a special connector ? :S

well you need a crossfire compatible motherboard which yours is.

All you do is connect the cards via a crossfire bridge, which should come with your motherboard and/or GPU's.

Then you connect your monitor cable into the top card (Not sure if it makes a difference which card you connect to the monitor.)

You also have to enable crossfire mode, which is a option in the catylist control centre (CCC) and bob's your uncle, fanny is your aunt you have crossfire. :p 


P.S HAPPY NEW YEAR YAAAAAAAAAAAAAAAAAAAAAAAAY!!!!!!

The important thing with crossfire is to pick out the right motherboard. There are a lot of motherboards that are crossfire capable but the second slot runs at x4 speeds which greatly limits the advantage of adding a second card. So look for one that runs at at least x8.

Picking this baby up :) 
One of the best socket AM3 mobos crossfires at x16 :D 
ps: since hd 5770 is a dx 11 card don´t i need a dx 11 capable motherboard , is that one dx11 capable?
ps2: is every monitor compatible with crossfire? I´ve seen monitors that aren´t compatible with ati cards for instance will CF be an issue with my old beat up LCD if my plan goes south and i can´t come up with the money for a new monitor as soon as i had planed
ps3: how are the temps of the hd 5770? i heard that the hd 4870 in CF reached very high temps and it was hard to keep.. I´ve heard that ati has tried to mend the 48xx series heat problems in the 57xx and 58xx but can i keep two of those in CF with my case and PSU?
December 31, 2009 7:24:53 PM

I´ve seen some benchies of a guy with the same build as me and a hd 5770 ( except the rams)
And he reached 60 fps in far cry 2 everything maxed out @ 1440x900 and 30 fps/everything maxed out in crysis @ 1440x900 aswell
That are some pretty impressive numbers since far cry 2 and crysis are pretty demanding

That is a nice motherboard, expensive though.
DX11 has nothing to do with the motherboard, just the video card, so you are fine.
Every monitor is fine for crossfire, every monitor should work with ATI cards in general as well so I'm not sure where you heard that.
One of the good things about the new ATI cards is that they are manufactured on a 40nm process which means they are very low power for their performance and thus give off little heat which is great for crossfire setups. Here is a power consumption chart where you can see it actually uses less power than much weaker cards;
December 31, 2009 7:51:17 PM

Nice :D 
Hmm the exits from the hd 5770 card are dual-dvi , my monitor is VGA and im going to be with it until i can buy a new one.
Im thinking of converting the far end of the VGA cable that goes to the GPU into DVI with a VGA female DVI male converter , will that work?

DX11 has nothing to do with the motherboard, just the video card, so you are fine.
Lol i saw that an asus mobo had improved to dx 10.1 , maybe they were talking about the onboard GPU.

One of the good things about the new ATI cards is that they are manufactured on a 40nm process
So they should OC well aswell :) 

PS: thanks a lot jyjjy and omgitzfatal you have helped me a lot with my new build :) 
You have shed light upon my ignorance

The cards usually come with a DVI to VGA adapter so I don't think you need to worry about that.
Looking at your build from the first post one other suggestion would be DDR3 1600 ram. It's faster than the 1333 and these days the price difference is usually minimal.

One large advantage to getting a single 5850 today over a CF solution is that when you want another performance boost, you can just add another one to your configuration.

Also, CF and SLI solutions aren't always supported by every game and have a few quarks to deal with.

Yeah i know i´ve been researching
The 5770´s in performance are equivalent to a 5850 witch is superior to the 5850 on many ways
And this build is perfect for me , i buy a single 5770 then after some time if i think my pc needs an extra boost i will put another one in CF
But right now and hd 5850 would be to much for my setup plus i don´t have the money to buy one
Im aware of the problems thanks.. But nowadays most of the recent games support CF and SLI better and this support will increase even more so when i pick up the second 5770 i hope the crossfire support will be better

The cards usually come with a DVI to VGA adapter so I don't think you need to worry about that.

The reason my card is so cheap @ pixmania(130 euros for a single hd 5770 saphire card) is because they come only with the CF bridge

But an adapter like those only costs about 8 euros so that won´t be a problem

Yeah i listed DDr3 ram 1333 MHZ because Phenom II´s native memory frequency support is 1333 MHZ but i think im going for OCZ obsidian 1600 MHZ with this mobo and if i have problems i underclock them

5850... 4870 are up in price and will end up sucking more power than your 5850. Let's not forget about heat and space issues as well.

Sell your 4870 and get a 5850.

Also, double 16X is only necessary for quad gpus (double GTX295 or 5970) setup, something that you definitely don't need.

By the way, you should pick a PII 955 if you plan to use an Asus board. The 965 is not compatible with a lot of Asus board on 790 chipset without a BIOS update... that you can't do without an older cpu...
January 1, 2010 1:23:25 AM

Well, after some reading I really need to give you a list of components...

Save some money over your CPU and your motherboard (that is way overkill for your graphic solution) and invest it in a single 5850. It's a little weaker, but it's a DX11 card, way... way... way more efficient and generate less heat than 2 cards.

Get DDR3 1600 memory, you can OC them to 1600 easily in your BIOS.

And... an Antec 300 for two 10 inches card (if you crossfire your 5850) will probably gives you a headache. A HAF 922 will really make a big difference.

Phenom II X4 955
4 GB of DDR3 1600 (OCZ platinum is the only thing I buy... never backfired me)
Asus M4A78T-E
Radeon 5850
OCZ Z 650 80plus silver certified (better and cheaper than Corsair HX)
Cooler Master Hyper 212+ (if you want to Overclock your cpu only)
Cooler Master HAF 922 (if you plan to Crossfire later, you need space... a lot)
