Nvidia GeForce GTX 560 Ti review to kick off this section. http://www.maximumpc.com/article/reviews/msi_ngtx560_ti_twin_frozr_oc_review I don't know anything about it, but I bet it would render some serious draw distance.
It's an even more efficient version of the Fermi architecture. I've heard it's only marginally more powerful than a GTX460, but will have much lower power draw. I'm not sure if that's enough to justify what will probably end up being a significant difference in price. Basically: GTX460 = Radeon 6850 GTX560Ti = Radeon 6870
I like the Ti naming, reminds me of my Ti 4200, where one of the better cards backthen. It was standing for Titanium if am right
It is basically is to a GTX 460 what a GTX 580 was to the GTX 480. A fully functioning part with higher clocks and better cooling. It should compete well with the 6870 and 6950.
I'll see if there's a good single card solution by the end of this year. I like the GTX 580, but it's still quite pricey. I'm not paying $500 for a video card. Video cards get outdated too quickly.
