Ok, so the pricing is about the same depending on company, so for high demand games which is better on a 2560x1440 resolution. A 2GB 670, or a 1.5GB 580. Thanks for any input

I like the first link, Kronos. Beside Wattage, the other stats mean absolutely nothing. 670 looses everywhere, yet it more powerful than the 580.
The GeForce GTX 580 features a GPU core clock speed of 772 MHz, and the 1536 MB of GDDR5 RAM runs at 1002 MHz through a 384-bit bus. It also features 512 SPUs, 64 Texture Address Units, and 48 Raster Operation Units. Compare that to the Geforce GTX 670, which has a GPU core clock speed of 915 MHz, and 2048 MB of GDDR5 memory running at 1500 MHz through a 256-bit bus. It also is comprised of 1344 Stream Processors, 112 TAUs, and 32 ROPs.
