Classic question i must admit, but since i'm on the lookout for gfx and i want top of the line, can someone tell me what the differences are? Which one is better at what?
Depends on the game. In general though, SLI or crossfire leads to a few more headaches/incompatibilities (so give serious consideration to the 4890 and 285.)

What are these headaches and incompatibilities? Right now I'm trying to decide between a 295 or two 285s? I'll be running either on an i7 / p6t deluxe v2 build. Also considering connecting a 19" lcd in addition to my 24" if that matters.
I made it sound worse than it really is. I just meant in some (even brand new) games you end up with 1 card instead of the 2 you paid for. Also, since the drivers are more complex you can end up with a few more oddities. That said, I really liked my 6800GT SLI back in the day. I just think it is best to start with one top of the line card and add a second in SLI/Crossfire down the road if you need it.

If you can afford to do it............ the 2 - 285's. Will run cooler and get better performance. The 295, although better than the 9800gx2, ( 2 on 1 ) will hold heat like a wool blanket. ...... Having said that, 2 OC'ed GTX260's in sli are pretty un-stoppable but I still like the idea of having at least 1gig of memory on a card. Good Luck.
SLi/Xfire gives you more power for performance, but if you get, say a 4850x2 which wasn't supported by official ATI drivers, then you'll have bugs and performance issues in games.
I currently have two 9800GTXs (1 GTX and 1 GTX+), and the only issuefor me is I need to disable one to play really old games. It works perfectly for newer games.

Really it doesn't I upgraded, last week, from an 8800GTX to a GTX295 and my core temps dropped ~5C. With a slight OC my GTX295 doesn't get over 76C ...not cold...but there's warmer cards.

the 8800 GTX ran on a 90 nm, ur comparing 2 55 nm die shrinks with alot more efficient circuitry. Remember that.
And don't forget the 295 GTX loves to pump out heat into the case rather than exhausting it out the back, because of Nvidia's quick sandwich idea.
Its not a bad card, I just don't think it has a place in the market with such a high price tag, when it came out 6 months after the 4870 X2.
It would be more understandable if it were a revision.
Even the 285 GTX (atleast here in canada) is more cost effective in general.
You can grab a 285 GTX for 325-350$ from BFG some even offering MIR, while the 295 GTX is still around 600$. The lowest I've seen in retailer stores here is 525$ after MIR.

I do live in the US where I paid $499 for my GTX295...$70 less than they wanted for a 4870x2
thats the first I've heard of a 295 GTX being cheaper than the 295 I'll tell u that much
and remember the advatages the 4870 X2 has, being able to crossfire witha single 4870, instead of having to pay 400$ with out a choice for more performance.
Thats Nvidia's problem, they aren't innovative and don't like to make it easy for the consumer.
With both companies you win some and lose others.
I mean with ATI, their drivers are problematic, 8.12 - 9.4 very un easy for consumers, but atleast drivers can be improved on (Alot of ATI fans will say otherwise, buts its true, they know it, it hasn't been the best season for ATI drivers, but I'll say it agian, drivers are always worked on and improved. Hardware, well once its out, its out. You won't see sli 295+ 275 GTX enabled through software, its very unlikely.
I would've been more open minded about hte 295 GTX all together if it had more Vram and 275 GTX sli support.
here is the cheapest 295 GTX I could find on newegg.com:
I wonder how in the hell MicroCenter is charging $569 for a 4870X2...maybe that's why they had so many in stock. Well, I'm not really a serious gamer, at least not yet, hopefully the GTX295 will play what games I may be interested in the future reasonably well at 2560x1600. Its working well now for HAWX so I'm happy. ...gotta get the sequel to Lost Planet and FEAR2
Ok guys after reading all of this hear's what i got to say.Directx11 i'm not going to wait for it.
4890x2 i would like to wait for it, but i need to build this pc now so i'm going to miss out on this one too.
So where does that leave me with the parts of today's market?
2xgtx285? Aint gonna happen. Why should i pay more than gtx295 and still get 2Gs of memory?
4870x2 vs GTX-295?
GDDR5 vs GDDR3.
3.6Ghz memory clock vs ~1.0Ghz
750 vs 576 Core Clock
2GB vs 1.8GB
512bit vs 896bit
Based on the specs, i can only see that gtx295 wins only on the bit interface, which i dont even know what that means? What does it mean for Ati to have 512 bit memory interface against 896bit of Nvidia?
If I were you, I'd hold out for a the 4890x2...even if that meant buying something retail in the meantime, using it up to 30 days, and then taking it back. I'm happy with the GTX295, but.....

Well, you have a difficult decision to make, but to answer your question up a couple posts: you can't directly compare the numbers to determine speed. The architectures are too different. In the end, the 295 comes out on top, but by a small margin. If you want the absolute best out of these two, it is the 295. However, depending on price in your area, the 4870X2 maybe be a better deal. 4890X2 does look like a beast, but I have no idea when they will actually release it and in what form/amount/price.

Thing is that if i get the gtx295 now, then when 4890x2 comes, i wont be able to combine these two into the same mobo, so it's either one or the other.
The 4870x2 i plan to get costs almost as much as gtx295.
They used wrong pictures on the site. The first one is with a single fan stock cooling.
The second card is the one with three fans - more efficient cooling at lower noise.
But you better call them and make sure...
Anyway I still dont get though how can the gtx295 have worse specs in every aspect except memory bit interface and still be a winner!
What you're seeing is that the GTX295 is a nasty-black-nasty beast. It asks no questions, it has no remorse, and it will not stop until it rapes your games and leaves them panting...its just nasty like that. Trust me, I know.
P.S. I have that 3-fan Artic Cooling chiller on my 8800GTX, its quite effective and quite nice.

Another option would be a 3way solution, which currently really isnt an option with a 295+275, but going with a 4890x2 and a 4890 would do it. Quad setups lose alot of potential. alot more than going 3 cards

I didn't take mine quite that high (640 shader clock, a reasonable improvement over 576) but I'd imagine that you can make the 295 place nice with a 275, clock-wise.
Keeping in mind the 295+275 tri-sli solution would be down clocked here http://translate.google.com/transl [...] adeon-4890 we see them trading blows, but thats 3 275s together, not a 295/275 tri-sli solution. Obscure site, but the only 1 Ive seen comparing a tri solution with these cards

Keeping in mind, the 4890s oc well also, or most likely better. Its always best to stick with the same model/speeds. Theres no guaranteeing the clocks will hold. Since the 4890x2 isnt out yet, no one knows if a 4890x2 would CF with a 4870x2, but it wouldnt be the best solution anyways. Mix and match isnt a good idea

I only mentioned 4870x2+4890x2 cause 4870x2+4890 was already mentioned. And i thought instead of adding the 4890 in the mix, it could probably be better if i waited and add the 4890x2 instead.
BTW does that qualify as a quad crossfire or triple?
Thatd be quad. Each x2 , whether its nVidia or ATI is having 2 cores on each pcb, tho its using only 1 PCI slot. Its and advantage for those whos motherboards only have 1 slot, or those that wish to go 3 or 4 core setups.

Why was it mentioned that triple is a bteer and more efficient than Quad? Cause if i get the asus 4870x2 i may want to couple it with the same one, thus making it quad, which isnt optimal according to what was said here.
games seem not to scale to quad solutions so well, meaning you've spent a lot of money and not much gain in performance. The price/performance ratio for quad setups is poor.
But still a 4870x2+4870x2 setup would be better than a 4870x2+4890 although it's not worth all that extra money. IS that what you're saying?
Precisely.
That P6T WS is a baddass board. Wish I'd gotten that. Now, I've never heard of 6-way Crossfire, but it seems like it'd be quite a battle (pun intended). All jests aside, I don't think 6-way Crossfire would work.
4870 x2 does better in certain games and the GTX 295 does better in others. The 4870 x2 is WAY cheaper but the GTX 295 has more WOW appeal.
Na, not anymore...that is, the 4870x2 is not always cheaper anymore. Micro Center had the Diamond MM 4870x2 @ $569 and a BFG GTX295 @ $499...so I got the latter. Perhaps it was just a pricing mistake or they'd just not stickered the x2 with current pricing but it was $569 on the box.
Well the Asus 4870x2 that i'm gunning at is not at all cheaper, since it goes for 485 Euros while GTX295 is 495, so there's not really a difference.
Well i really wish i could go for the 6-way crossifire. It looks like a badass board, but if you can't get the 3 double core gfx then what's with the 6 pcie slots? Paying all tha money so that you can only get to 3 single core cards? Is this really worth it? On the other hand 3x4870x2 that would be like leaving the dream, i mean come on, pleas tell me this can happen, at least at some point in the future.
...since I live .25 miles from one sometimes I forget that there's...others that sell stuff too. LOL
yeah I use to do that... I while back... Now Newegg and google are my best friends.
It's a competitive market out there, so do a little research before spending your hard earned money
6 way isnt a viable option, we get bad performance using quad setups at best. No drivers are made for that combo,6x, outside of gpgpu work, which isnt gaming anyways

What about GPGPU on this case? I need gfx power for CAD application so even if they couldnt be utilized for gaming, it would stil be practical for cad rendering for me, if that's what you mean.
my suggestion would be not combinging the 4890 witht he 4870 X2, since its a waste of money.
You'd benefit and save alot more if you just buy a 4870 1 GIG, remember 4870 won't be able to OC as much as a 4890, and you'd be forcing your X2 card to run stock 4890 in order to get your money's worth.
ANd if youd on't oc all cards will run at 4870 X2 frequencies.
I'd have to say that 1 4890 should do it for now, I think the fastest multi card setup up to date would be 285 GTX tri followed by 4890 tri.
The quads tend to have issues, especially the 295 GTX since it hits the Vram wall. faster than the 4870 X2.

I had the 4890 for a few days and took it back and got a GTX295. While the 295 obviously beats the 4890 I will say that at 1920x1200 and below the 4890 did quite well and it did okay at 2560x1600...especially good bang for the buck ...gaming @ 2560x1600 is an expensive proposition...not sure I'd recommend it unless you've got a 30" monitor and that extra $200 bones is really...extra.
