There is a new 560TI card coming out next week(Nov 29) based off the 570 card. It will have more shaders, memory bandwidth, and memory 1.25gb. This is the card i'm looking at for BF3. But it may also drive the current 560 and 560TI down in price.
Intel I7-4770K, MSI Z87M, 8gb G.Skill DDR3, Asus 970 Strix, Sandisk 240gb SSD + 1TB WD Black, Cooler Master Hyper 212 EVO
