I'm looking to upgrade soon. I was going to get the 590, then I just discovered (about 10 minutes ago) that there's a 3GB version of the 580. I'm no GPU expert, but I'm aware of the limitations of a dual GPU card having owned a 295 for nearly two years. Isn't it better to have all the video memory on a single GPU? If so, is the 590 bettered before it's even released? I'd also bet that the 590 will be more expensive than the 3GB 580.
if what you trying to say that more memory=better performance that is completely wrong For instance if that was the case a 9500gt with 1gb would have been faster than gtx460 768mb What matters most is amount of shaders, gpu/memory/shader speeds, texture units, amount of rops and the architecture of the chip ( a newer vga with newer architecture will be faster than a same spec vga with older architecture ) 5970 should provide better performance compared to a gtx580 but the question is are you gonna use that 590? a gtx 580 has more than enough performance for every game at 1920x1200 hell even at 1600p is more than enough and will last you years to come ( hell even a gtx560 is more than enough ) In fact your gtx295 is still one of the fastest gpus so i suggest sticking to it at least until 2012 or until we see a VGA with significantly improved performance over that gtx295

Memory does not equal preformance what so ever. If that was the case stuff like the 5450 should just be as powerfull as the 460 or w/e. more ram just allows a higer resolution.
All the extra memory is going to do for the GTX 580 is allow it to maintain stable framerates in certain games at really high resolutions. That's it. In most games I bet you wouldn't even see a difference in performance between the 1.5gb and 3gb versions. The GTX 590 will be significantly faster. GPU horsepower> memory bandwidth> framebuffer in most scenarios.

What I was trying to say is the 590 will have two 1.5GB 580 GPU's on a single card, equalling 3GB. The 3GB 580 is the same GPU so we aren't talking about older GPU vs newer GPU with less memory, like your comparison of the 9500gt and the GTX 460. We're talking about the same GPU: x2 1.5GB vs x1 3GB. I'm no GPU expert so I'm just trying to understand why two GPU's with 1.5GB is better than the same GPU with 3GB. I'm looking to upgrade because I've never really been happy with the performance from my 295. It isn't as good as I was expecting. In Crysis 1920x1080 Very High, it's practically unplayable. Mafia 2 benchmark @ 1920x1080 max settings and Apex Physx on High gives me an average of about 27fps. I want to be able to have good frame rates with everything as high as it can go, the GTX 295 has never provided me with that.

In a dual GPU card each GPU can only use 1.5GB of framebuffer. They do not add up to equal 3GB. It acts as two seperate cards with 1.5GB of GDDR5. The same GPU with 3GB of GDDR5 is better because it can use all 3GB of VRAM and not just 1.5GB of it.
But a duel 580 card, the 590 will also have 2*512 processing core, the thing which actually chuck out the polygons. A 3gb 580 still only has 512. mucgoo
True. There will no doubt be 6GBGTX 590's that have both dual cores and 3GB of GDDR5. I doubt that the GTX 590 is really two GTX 580 cores on one chip. That would just use too much power to be PCI-E compliant.

I run Crysis at 1080p on very high at around 30 fps with my specs so I think somethings wrong on your end. You should monitor your CPU/GPU temps to make sure something isn't overheating. Also you should check to see you have all the latest drivers installed.
The 3 GB GTX 580 is primarily for people with large monitors or surround setups. The screen space is so high that the 1.5 GB 580 was not enough for three 1920x1200/1080 monitors or higher. By doubling the memory, in SLI you have a staggering 6 GB of memory to pump up the resolutions. Itndoesn't really pay to have a GTX 590 or whatever as the price per performance will be horrible. The GTX 580 maxes out every single game out right now for the majority of people.
