Dude. Just go for a new system. I highly recommend it. You are running a low power core. It only over-clocks at 3 ghz. I would recommend salvaging and selling the parts and buying a new system. Go for an hand made system. LGA 2011 with a ram max at, at least 32 gb. That is just me though. I have no idea what you do with the system. If you give me more info I can help. And just for perspective here is my system.
Intel i7 quad core. 4 ghz. Over clocks at 4.5 ghz.
128 gb ram.
Radeon 5700 series. Total of 6 gb of DDR5 ram along with the 2gb card.
