GTX295 (two GTX275 cores, with lower clocks)
GTX460 2Win (two GTX460 cores, obviously)
GTX590 (two GTX580 cores, with lower clocks)

Every other GTX card is single gpu core.

And yes, GTX295 is SLI on a single card.

The OP question has been well-answered ... hot, loud, power-inefficient, no DX11 are the main drawbacks. But also, since memory amount in SLI isn't 'additive', if you go w/quad-SLI 295's you have a TON of GPU power ... but you still only have 896MB of effective VRAM capacity. It's just not a well-balanced setup in terms of GPU power vs. VRAM amount.

The 295 isn't two 275, it's two 285s with the 275 VRAM. The cards will still do any game on max with 60FPS, minus some 1GB+ games.

I had that setup and loved it! You will lose DX11 but have tons of power! The only time I didnt like them was when the games didnt play well with SLI, they you had to turn it off and run on one core....and that sux.

And you can leave the computer out in the winter and just run the cords into your house

Seeing as it snowed like 1-2feet in most of Colorado this winter.

Anthrax, what I said was not incorrect.

The GTX295 is, architecturally, in every possible regard, two GTX275's on one board.

However, it runs at the reference GTX260 clocks, rather than GTX275 clocks.

I rocked a 295 for almost a year ... I know exactly what they are

Wow, I thought it had the 285 shader amount. My mistake.

You're not mistaken ... it does

You see, the 275 does use the 285 chip (240 shaders, 80 texture units, etc), however it has the vram setup of the 260 (28 ROP's, 448-bit bus, 896MB of vram).

The downgrade to the VRAM (and associated components like ROPs) are what makes a card a 275 rather than a 285.

And the 295 is exactly two GTX275's (at 260 clocks).

In other words, you weren't wrong ... except for when you implied I was wrong ... 'cause we're actually basically saying the same thing

cool to see you are a mod now brettjv, very deserving!

my 295 is still going strong in my step-sons rig great card.

I had 2x 295's

Very capable set up if you are getting them dirt cheap then it may be a great deal.

DX 11 will not be a factor for the foreseable future as I see it.

As stated above, what are you paying, that would be the correct question

Are they worth this price ???

They will destroy just about any game out there so where is the cut off that is simply makes more sence to go with a more up todate card

The reality is they are just a bit shy of a 480 and bit better than a 5870 in most games

Taking for granite they would scale aproxamently the same

So the cheapest 480's I could find were $ 299.99 ea.

so your price point IMO should be around that and being they are used significanlt les

$ 175.00 a peice is the max I would pay ... being the other factors Power consumption, no DX11 and used

good luck

The gtx295 sucks for people who have 1080p Its very limited by its vram and memory bandwidth. Two of them is even worse as it still has the 898mb vram.

Terrible card really, I would sell it and get a gtx480.

Anyone that says a gtx295 is close to a gtx480 is an idiot. Try running Bad Company 2 on both and see how the gtx480 destorys that game, 1 gtx480 will play bad company 2 with 16xAA completely maxed out in Dx11 while the gtx295 wont come close...
