My brother is helping me build a new computer. I already know which CPU, motherboard, case, PSU I want. One thing I am not certain is which video card to get. I primarily play games like Sims 3, Spore, Sim City 4 and Second Life. After much research, I have narrowed it down to two video cards. AMD Radeon HD 7950, 3 GB 385-bit GDDR5 memory, OpenGL 4.2, PCIe 3.0 x16 nVidia GeForce 560 Ti, 2 GB 256-bit GDDR5 memory, OpenGL 4.1, 2 DVI & 1 HDMI Which of those two graphics cards is faster? Which GPU is more capable at ultra high settings with texture & lighting on and anti-aliasing set to maximum? Which one is best for SL?
