I could probably choose myself, but I'd like a second opinion. I have an Intel Core i5-4440, with 8 GB of DDR3-1600 RAM and an EVGA GeForce GTX 750 Ti. At full load, it barely uses half of my PSU's 500 watts, so wattage is not an issue. I can run most games at 1080p at high settings at good framerates. However, some games require me to set them to 1600x900 to be playable. What is a good GPU that would be a significant upgrade from the GTX 750 Ti, runs well with my current processor (no bottlenecks), and costs less than $200 (or maybe $175, lower is better, i'm on a budget)?
