What's a GTX560 Ti, you may ask? Put simply, it's awesomeness condensed into the shape of computer hardware. Put complexly (because I can't resist talking about the details), it is the second generation of the nVidia GeForce 460 - the 400 series was replaced with the 500, so the GTX460 (apparently a very popular GPU) became the GTX560. However, to bridge the performance gap between the 560 and the 570 (which was relatively considerable) nVidia came up with another "in-between" version, the GTX560 Ti.
Why am I talking about this particular GPU? Well, waaaaaaay back in December 2011, I bought my current desktop PC, a Gateway DX4860 with an Intel i5-2320 processor @3.0Ghz, 6GB of 1333Mhz RAM, a DVD drive, about a dozen USB ports (you can never have too many USB ports) and finally a nVidia GeForce GT520. Not the best card out there, truth be told - I looked it up on an benchmarking website and it was third from the bottom.
However, it was millions of times better than the GPU I have in my good-ol' laptop - an Intel 965 Express Chipset, which sometimes struggled to run even Age of Mythology - not exactly the most graphics-intensive game out there. (I don't even know why Intel makes GPUs O_o)
