I need some advice for future purchases in order to prevent bottleneck

[james1994]

Hello everyone. I recently built a fairly new pc and here are my specs.
Cpu amd athlon x4 760k
Gpu msi r7 260x 2gb OC
Mobo msi A78M-E35
Ram 8gb ddr3
Psu 430W
Win 8.1
1Terabyte Hdd
Im considering selling my psu and gpu for a 500w psu and the r9 270x. Im afriad of bottlenecking. Can someone explain that to me what bottlenecking is and is their a chance that could happen?

It looks like your motherboard and power supply are the first two things that you need to upgrade. I'm assuming that is the Corsair CX430?

Why would my motherboard need an upgrade? and yes your correct corsair cx430

The motherboard is not as bad as I originally thought, but that is a bottom budget psu. You were right in the beginning about upgrading to a 500w psu and getting a better video card. You could also buy a $29 Cooler Master 212 Evo and overclock that 760k.
