why is it reporting an i5 , and an i3 processor ?
what graphics card you should get depends on
1/ your budget
2/ the resolution of your monitor
3/ the power supply you have fitted
without that information anyones guess is pointless
Sorry about that.
I have a 500 watt cooler master PSU, monitor/tv with resolution is on the pic (1360x768) , and I plan on spending 200-400 on GPU alone. Don't think it would be that expensive if I have this setup.
