Hello, ever since I've had my PC it has had an AMD A8 5500k APU that bottlenecks the crap out of my AMD 7850 Dual CUll. I just ordered a new MoBo and i5 4670k so that will give me WAYY better performance and show what the 7850 actually can do. I was sticking to the idea of getting and AMD R9 280x and I have to get a new PSU with that too (I only have a 500w atm) The GPU and new PSU will run me about $375. There are no benchmarks of the 7850 going against the 280x so what I'm asking is, is it worth the money to upgrade and will the performance boost acount for the extra money spent?
