  1. To buy a better processor, you also need a new motherboard. Depending on what graphics card you're looking at, you might have to upgrade your PSU as well.

    I'd go the graphics card route first, but you might be held back by your processor.
  2. I was looking at getting ::EVGA GeForce GTX 750 Ti Gaming Graphics Card - 2GB GDDR5, PCI-E 3.0 16x -

    Just concerned that with the older mobo and processor if I would get a bottleneck as this may be too much video card for the older system.
