Honestly at that resolution you probably don't need either of those setups. I would go with the 4870x2 just for ease of use however as if you are going to deal with multiple GPUs you may as well get it all one card. Then down the road if you insist, you can add another HD 4870x2 for more performance.

If money is no object, the absolute best graphics performance available presently would be a Triple-SLI GTX 285 configuration. However, that level of performance would only be available in games that fully support/utilize SLI properly, as not all games do.

Since it seems you may be limited to two PCI-E slots, as it implies in the choices you outlined, your most powerful configuration would be using the 4870X2 along with another 4870 installed in the 2nd PCI-E slot, creating a Triple-Crossfire configuration. Triple-Crossfire is not something I have any personal experience with, so I cannot comment further on it's stability or support, though I have seen some people report problems with it.

If a triple-GPU solution would be too difficult a setup to maintain and troubleshoot in game titles, the final option would be a dual-GPU solution called the nVIDIA GTX 295. It's two GPUs in one card, like the 4870X2, so it would only use one PCI-E slot.

I should mention that all of these would be overkill for a 22" monitor and would require a very high-output power supply of 1000W or more.

Edit: A single 4870 would be sufficient for that resolution. I'd go with a 1GB version just in case you upgrade to a higher resolution monitor later.

My motherboard would be xfx x58i which supports both sli and crossfirex .it supports tri sli but i'm not sure about tri crossfirex configuration.one more thing , i heard that in 1650x1050 res with hd 4870 x2 games would be very cpu limited . Is that right ? I would have thermaltake 1000w psu.

Well 1650X1050 resolution, 4870X2, 8GB DDR3 doesn't go well together...
Could you post more info on where you are planning to buy the parts, whether you will be assembling it or pre-built system, budget, any parts you have???
We could suggest better options...
April 20, 2009 7:40:57 AM

4870x2 should be fine. Why not 4870 CF? $135 each ASUS.
If you want 4850, checkout the ASUS Matrix that's been reviewed on Toms. Nice OC options.
April 20, 2009 8:03:39 AM

I've just fixed these things in my mind for buying and now searching the net for any better opinion. Money is no problem for me . I would buy anything except 22" monitor because i don't like big screens.at first i thought that i would buy three gtx 295 but i thought about future especially about dx 10.1. So i'm going to ati.
April 20, 2009 9:56:37 AM

You can't use 3 GTX 295 in one computer (Dunno about PhysX). If money is not an issue, why not get the best? 4890 3CF?
a b U Graphics card

While you could buy 3 GTX295's, only 2 of them could be used at once in an SLI configuration, as that's already a quad-GPU solution. The 295 is a 2-GPU-in-1-card solution.
April 20, 2009 10:09:46 AM

That's what I said. What I asked was if the 3rd one could be used for PhysX.

i7, 8GBs, X2 video card, 22" LCD, sounds like a guy who has lots of money and no clue. (Later confirmed with the "Money is no problem for me . I would buy anything" comment") Nobody puts 8GBs with the i7, they use 6GBs due to the triple channel memory controller on the i7. As mentioned by Jaysin, all the options discussed so far are overkill for a 22" LCD. If you don't want to worry about any current game at that res, get the 4970. Even the 4870 1GB would be fine. We are talking about 1680x1050 or 1600x1200 here. This is not a huge resolution requiring CF or x2 cards. An i7 with 6GBs and a single 4970 might not be as sexy, but without wasting money its all you need for 1680x1050.

Damn rags... Trying to get under my skin or something? We didn't say quite the same thing, and look at the post times... we were replying at the same moment. LOL

Chill the F out dude!
April 20, 2009 12:27:35 PM

Anyway, can a third one be used for PhysX?

4970? Since when could you "get the 4970?" There's no such card yet.

April 20, 2009 4:36:30 PM

^That's good, but OP says money is not a problem. So 4890 1GB CF should do great.
April 20, 2009 6:14:06 PM

Will not the hd 4870 x2 in cfx be better ?

Upid, have you bothered to read the recent Best graphics cards for the Money article? If not, read it in it's entirety and start basing your needs from it. As has been said and probably not stressed enough, at your resolution anything more than a single 4850 (or perhaps 4870) in a 512MB configuration would be overkill. That article should help explain why.

2 quad cores and 64GB memoy
(this is a joke, but it would work!!!)



That's actually not bad, since the total comes out to less than $3000. An Alienware gaming desktop with only a quarter of the processing power would cost almost as much.
April 21, 2009 1:28:14 AM

I play at 1440 x 900 and I do not find the 4850 overkill. I could even do with a 4890 OC. But since he has the money, it 4890 CF will result in quite high min. fps ensuring smooth gaming.

Both the 4870x2 and 4850x2 use CF. In that case, single card - 4890 1GB.

Sure there are faster cards out there, but you'd need a bigger screen for them to show their power. Remember, we are talking about a 22" LCD. X2s and other such cards really need bigger screens to make them worth it. He can always spend his money on harddrives, keyboards, laser mice, sound system, etc.
April 21, 2009 9:12:31 AM

You're likely to get BETTER performance with a BETTER card, no matter what the resolution is.

Why not 3 gtx 295 work in tri sli ? Is it because of that the gtx 295 has dual pcb so that we can use 4 gpu in sli ?and hd 4870 x2 has a single pcb.so , can't we use 4870 x2 in tri crossfirex or four ?

Because every dual-gpu card out there (48x0X2, 9800GX2, GTX295) is already using SLI or CrossFire technology to link the two GPUs on the card, and you can't have more than 4 GPUs in SLI or Crossfire, so 2 of each of those cards is the maximum.
a c 171 U Graphics card
April 21, 2009 10:48:52 PM

Read what he said. Two of the GTX295s would be in a quad SLI setup, while the third would be handling PhysX duties. (I don't know how possible this is, not sure if the GTX295 will work as two GPUs handling physx or if one will be turned off.)

Again, it doesn't really matter. The 9800GTX/GTS250 can handle 16x10 with ease. Get two of them for much less money if you want to stupidly waste cash. Without a larger screen you won't see what these cards can do. Period.

to the OP:

there are 22" LCD panels that can do 1920x1080, you should look into that. at that resolution, its justifiable to get a multi-gpu configuration.

Without a larger screen you won't see what these cards can do. Period. said:

depends on the games that you're talking about. and the degree of gameplay fluidity in question. i dont believe a gts250 can handle tc:hawx with vsync-on @ that resolution, unless proven otherwise.

What makes upid think the 4870x2 is any different than the 295? It's even got an x2 to its name! And I've always wondered whether we could use a dual GPU card for PhysX. Isn't that like using 1 285 out of three for graphics and the other 2 for PhysX? Or can you use only one GPU for PhysX?

Why do you keep saying that? I really could do with a better card even if I run at just 1440 x 900.

I think he's trying to point out that if he had a 4850/70 or similarly powerful nVIDIA card, he'd see little performance gain from anything more powerful because those cards will run even the most stressing of games with FPS averages of ~50-60 or more at his resolution. Anything more than that frame rate is hardly noticeable. That's the point he's stressing.

Personally, I really don't care what Upid buys at this point. Let him waste $2k on 4 GTX295's and be stuck in a shyte performing 4-way-SLI with $1k worth of GTX295 paperweights.
April 22, 2009 3:49:21 AM

^Lol. 4890 should do fine for anything except Crysis/Warhead. That's what I meant. I'd be better off with a 4870/4890, not GTX 295 8-SLI :D 
April 22, 2009 4:20:20 AM

People, after so many opinions i am thinking for getting a bigger display like 19x12 res.and also thinking for two 4890 in cfx . Won't it handle games like crysis warhead,gta 4, farcry 2 in maximum settings at that res?

thats an affirmative for farcry2;

gta4 thats a negative.

crysis warhead? i think so, but limit yourself to no AA or up to 2x AA.

if you have a tri sli mobo, you can only use the 285's in tri sli, you are restricted 2x 4870-4890's in this case as there is not enough space to use 3 ati's...
