How well will the Phenom X4 9950 perform with a lower end GPU like the R7 240 or R7 250? If anyone knows any other good AM2 CPUs or knows how well this one will perform with a low-end GPU, please, state it in this thread. (optional question: How good out of 10 would you say the Antec Nine Hundred Ultimate gamer's case be compared to the X-Blade?)
