I disagree. Even though the GTX 750 is more powerful than the R7 250X, the GTX 750 can only support 3 monitors at most while the R7 250X Flex can support up to 4 monitors in a normal configuration and 6 monitors if a MST Hub is used. Since this is primarily a stock trading rig, I believe that multi-monitor support should prioritized over gaming needs for this rig.
Hmm.. i think i will only be using 3 monitors maximum at this point in time. WOuld a GTX 750 suit me better then? thanks!
