Should I get a FM2+ CPU to upgrade to PCI-E 3.0

I'm a 58 yr. old newb who recently bought a Cyberpower desktop with a Gigabyte F2A88X-D3H MB with a A8-6600K CPU not knowing that to have my MSI R9 280 3GB video card operate at PCI-E 3.0 I needed a FM2+ CPU. I am a strictly single player first person shooter and website purchaser so I'm looking for the best bang for buck FM2+ CPU. Have been looking at the A10-7850K ($150.)

Using PCI-E 3.0 will not do anything for more vs PCI-E 2.0 can do with the gpu you have.

Why on earth you'd go for an APU setup is beyond me. You should have gotten a board that had AM3+ support and got yourself an FX CPU along with your GPU. As you have no use for an APU setup and it's a waste of money when the alternative would have been the optimal option.

Link to CPU you asked for

Though I'd recommend sending that whole system back and doing a FX build on a board AM3+ capable. As that APU for it's price is a joke, and will offer you nothing but headaches. Essentially you have a chip with both a CPU and GPU on a single dye, so it's not all that great at doing either of those tasks when compared to what I have mentioned above.

To anyone who comes to this thread AVOID APU systems for the time being unless you can not afford a GPU and good dedicated CPU.

@04dcarraher: Ya he might gain a couple frames but not enough to really be worth any decent investment.

He wont see any gains, especially with the cpu he is using, and to the fact that his 280 is nowhere near maxing out pci-e 2 bandwidth. The difference is less then 1 frame 99% of the time, and that is dealing with gpu's much stronger. there is no significant performance difference between x16 3.0 and x 8 3.0 vs x16 2.0, which offers the same bandwidth as 3.0 at X8. The average difference is only 1%, which you'd never notice

Which is why I mention a couple of frames isn't worth it.. I think the most I've ever seen gained by switching to 3.0 was 5 frames, and that was on a 780ti I believe so ya not worth it for the $160. Still think that system would have been far better had it been AM3+ with an FX-8350 though.

Even FX-8320 would have been better and FX-8320 is the same price as A10-7850K.

@insane_metalist: Agreed.

This.
