but its crazy if you buy >$400 GPU just to play games in low resolution and medium detail?
I'm not talking low resolution, I'm talking the most common resolution used today 1080p. Yes, some might be using higher resolutions, but even then the card probably won't bog down that much due to 1GB of memory in most modern games. I've never even seen BF3 on ultra settings break 1024MB actually at 1080p.
And as the marketing says, the card has the
framerate to win. I think people with 1080p 120Hz monitors would be very interested in this card for 3DVisison to achieve the 120FPS they need. At 1080p they are more likely to get 120FPS with this card than a GTX580.
There are some very big problems with this card, according to PCPerspective (1 and 2):
1. The card requires an SLI certified motherboard, even if it's going to occupy just one PCIe 16x slot. This is because it's not an nVidia approved product, and there is no special profile for it in the official driver. This means that you could buy two GTX560Ti's and put them in SLI for about the same price (even cheaper).
2. The SLI bridge connector isn't really functional, they just didn't care to remove it in the production model. This is because the GTX560Ti ONLY has ONE SLI connector, and the driver thinks it's already in use. You can ONLY put two 560's in SLI.
3. Missed opportunity. 1GB RAM = FAIL.
4. Why in the world would you buy this (except the 3 monitor setups), when you can have one GTX580 for a bit less money and without the microstuttering and without any of the other multi-GPU issues. You could even get a 3GB GTX580 for about the same money, and have a sublime gaming experience, even on 2560x1600.
1.) You don't need a SLI certified motherboard. Not that this would be a big deal, considering every high end board has SLI(and if your buying a $500 graphics card, you better not be putting it in a sub-$100 motherboard, or I'll beat you). But besides that, you don't need an SLI certified motherboard, because just like the GTX460 2win, and GTX590, the PCB uses a nf200 chip to split the PCI-E lanes between the two GPUs. The presence of the nf200 takes care of the need for an SLi certified board.
2.) I don't see why this is a big problem, yes its there, but eVGA tells you it isn't functional. So big deal, you can't 4-way it thanks to nVidia's driver model.
3.) As I already stated, not really. Plenty of people are running SLI GTX560's right now, and I'm sure their are damn happy with them, even with only 1GB of VRAM. The cards scale wonderfully, and if you are after 3D, then this is the card to have, even with 1GB of VRAM. And everyone complaining about only 1GB of VRAM should read the reviews. Even at 2560x1600 w/ Ultra settings in the games, the GTX560 2Win outperforms the GTX580, usually buy a substantial amount. The only time really the GTX560 2Win drops behind the GTX580 is in BF3 w/ Ultra settings and MSAA cranked up, and at that point even the GTX580 is running at unplayable framerates, so that is kind of a useless data point.
4.) Why would people buy this? Well, because the marketing says it is better than the GTX580. And if you don't believe the marking(and you shouldn't) the reviews say so also. Even at 2560x1600, there wasn't a single game in any of the reviews where the GTX560 2win lost to the GTX580. So for the same price, or a few bucks more depending, you get better performance. That is why people will buy them.
