I' m just gonna play in 1080p for the next 4-5 years so no change of monitor.
I wanna know whether a r9 290 is a overkill for 1080p gaming.
seeing as the only difference is the GPU I'd say the system with the R9 290... it has more/faster Graphics memory which makes the most difference while gaming.
As far as overkill goes. I'd say no... overkill would be 2 R9 295x2's in crossfire
