So i've been poking around the CPU and Overclocking forum trying to find a decent cheap processor to run modern day games. I've been looking at some old desktop PC's to buy and hopefully be able to upgrade to fairly satisfactory standards. I've seen a few YouTube videos of people with Intel G3258's and i3 4130's running smooth as hell. So since i've pretty much narrowed that down, I'm looking for a compatible graphics card without breaking the bank. I've been recommended the GTX 750 ti multiple times. I've seen some gameplay videos and it looks pretty good. So i looked around and came across some refurbished graphics cards. Are these any good? Granted i know they probably have a higher failure rate but i wanted to know if i should look into it more or just pass them by.
