also the main reson for this graphics card is to stream, such games as league of ledgends and Minecraft

1. The super clock version has a little extra clocking speed(144Mhz) for an exta $20, so you have to decide yourself which one you want.

2. The GTX 650 super-clocked is better than the 550ti, so it's really up to you here. Try watching some gameplays and benchmarks between both the GTX 650 Super-Clocked and GTX 550ti, then make your decision from there.
