Nvidia and AMD have been waging a graphics war that's getting bloodier than ever, thanks to the release of Nvidia's 700-series and AMD's R7 and R9-series video cards.The green team's newest edition to the market is the 750 Ti, which provides gamers with an inexpensive 1080p gaming video card.Nvidia's small-sized 750 Ti runs only $149, half the price of the GTX 760, and just $20 more than AMD's R7 260X, if you account for the 260X's recent price cut.While the 260X is a rebadged Radeon HD 7790, Nvidia's 750 Ti features a brand new GPU architecture called Maxwell.In the past Nvidia has released new architectures from the top down, meaning they would typically release a high-end video card like the Titan and then slowly release lower-end GPUs with the new architecture.It's definitely a savvy move for Nvidia to refresh their low-end offerings first; at $150 the 750 Ti is an impulse buy compared to upcoming Maxwell refreshed Titan Black.Like other 700-Series cards, the 750 Ti supports G-Sync, a new technology from Nvidia that allows GeForce video cards to play games without refresh rate induced stutter or screen tearing.
