I recently went through a mix up with my manufacturer. I was recommended the GeForce GTX 750 TI. The first problem was, it would require me to disable my wireless internet connection due to lack of space on the motherboard. I fixed that by just using a USB wifi adapter. But now, I'm being told that I can't use a card that requires external power at all. I'm looking for the best graphics card that's price cap is 150$, and one that does not require external power. Thanks.
