Which one?

i have a i7 920 with a GIGABYTE GA-EX58-UD3R Mobo and HX620 PSU.

Please advise.
 
From what I've seen, it's nearly always better to choose a singe high-end card instead of 2 lower cards.

However, given the shortage and price difference, I think it depends. But, if your screen is only a 225BW (22"), I don't even see the need for crossfire 5770's, let alone a 5870.

I'd say: Single 5770 unless you plan on Eyefinity with 3x 22" LCDs. Then I'd say 5850/5870.
 
Since Eyefinity with DualGPU/SingleCard (a.k.a. 5970) works, it's only a matter of time before the drivers support xfire eyefinity.

However, don't bet on it.
 
Yeah personally I would rather go with the single card as well, but this shortage is killing me!

Ill be running one 28" Hanns.g so no need for Eyefinity.

Which setup will give me the best bang for the buck?
 
If price is no concern, then try to get your hands on the single card. Going strictly by MSRP, two 5770s will cost $340 vs $399 for the 5870, so it is a viable option if you aren't looking to spend that much. Almost all the new 5770s come with the cooler that doesn't vent heat out of your case, so that might be a concern of yours as well. In terms of best bang for the buck, two 5770s will perform very closely to a 5870 for less money, but I am predicting the resale value will be worse, and a 5870 usually comes with Dirt 2.
 
You can practically get dirt 2 with breakfast cereals. 2x 5770 will be quieter than 1x 5870 and there are editions of the 5770 coming with dirt 2.

I'd love for you to explain how in your world, two video cards are quieter than one when they use the same fan.

I'd recommend the 5870 as well, although it's tougher with the MSRP increase and shortage. If you can wait, do so.
 
I just got my XFX 5870 in my rig and not only do I never hear the fan ever, my computer room is def. not as hot compared to revving up the ol 4870X2

My wife's 5770 V2 is almost inaudiable at full load in furmark. 2 of the V2's crossfired are probably just as quiet. It sure as hell is not anywhere near as loud as the shroud coolers that come with earlier 5770's or in this case the 5850/5870.

Did you try overclocking it at all?
If so, what core/memory did you reach?

It's not mine to overclock :p

I just installed it, ran furmark for a few minutes and played Crysis and then let it be. I can try it out later tonight though.
 
No problem. Was interested how the core and memory overclock with the new cooler.
 
Single GPU before dual GPU. Always. Period. End of story.

This from someone with extensive experience with both SLI and Crossfire.

hes not talking about absolute performance. i think hes talking about the fact sli/crossfire are still iffy. many games make no use of the additional GPU/card and even the ones that have driver support for multi gpu dont always make full use of the additional power. thats why getting two 5770's versus one 5870 is not a good idea since price/performance(if cross fire 100% working) would be about same.

The shroud coolers are silent in normal operation (fan speeds almost never exceed 25%). These are the open design ones, I take it? I'd recommend going against them for other reasons, but good to know they're quiet.

No, always true. Never jump into dual GPU unless you absolutely can't get a single GPU solution to do what you need done. And reviews with simple charts and no FPS graphs or qualitative analysis are just this side of useless.

I used to feel this way as well, but you cannot use performance to justify this statement. It is a fact that two 5770s in crossfire are equivalent to a single 5870 in performance, for less money. However, compatibility with games and driver issues (no eyefinity yet in crossfire) makes owning a single GPU less of a headache. This has nothing to do with the raw performance ability of the cards themselves. In the games that properly support crossfire, you will be unable to tell the difference between crossfired 5770s and a 5870 without looking in the case.

Despite how much of an advocate you may be of dual GPU, you can always spot dual GPU vs. single GPU. You don't even have to tell me what a system is, fire up a game and I can spot it. Single GPU is just much smoother and consistent than dual GPU currently is, especially where performance is being stretched to the maximum. Until the technology for SLI/CF improves, dual GPU pales in comparison to single GPU.

Are you like the Michael Schumacher of video cards? Schumacher could tell the difference between transmission fluid viscosities, however he's a 7 time WC.

I have that monitor, and after going to the eyefinity challenge... I am seriously thinking about getting two more for xmas lol.

The three 23" screens were more immersive than my 28"
 
my friend has a single 30inch
and running a 5870

and my setting is a 3 * 22" eyefinity
with a 5970

after he tried on my 3* 22 set up with games like grid, L4D, COD4
he is thinking about sell his 30" for some 22"s or 23s( he just don't have money for 2 more 30")

you have to try to to believe it.

i was thinking about getting a 26-28" before..
but now lol i think i am set for now with my 3 22"
also they are the samsung 225BW same as the OPs..
( they are good monitor for eyefinity, as they have really narrow edge then some newer monitor)
