Hello, i need suggestions on what i should upgrade on my rig next too increase my performance. My current rig is. http://pcpartpicker.com/p/rM49Q7
My budget for this upgrade is $300.
Thank you
Well i think the gpu, u can find a nice r9 290x oc'ed from factory at that money, or a gtx 970. With a decent cooler u can overclock a bit your cpu. If you dont have one add it to your list.
Add another R9 270x for around $160 and then upgrade your CPU to the FX 8350 and you should see a huge difference for the lowest amount of money. Your PSU should easily support 2x R9 270x's
This would be my build http://pcpartpicker.com/p/jTjqyc or this http://pcpartpicker.com/p/8hY2NG, honestly i dont think changing ur cpu worth it right, u can overclock your current one without any problems.
EDIT: Here s the proof http://www.anandtech.com/bench/product/699?vs=697, scrool down to the last 3 or 4 becnhmarks, those are gaming benchmarks, the difference is very small bewteen fx 6300 and fx 8350, so it doesnt worth it, better buy a single better gpu to avoid cross issues (some games doesnt support cross so your fps will be reduced to half, or doesnt fully support cross and u will have about 10% improvment over your single 270x)
