Hello, i currently have an AMD A8 3870K, with its integrated graphics disabled, paired with a radeon HD7750. I am planning on upgrading the GPU to a GTX 750ti or a GTX 950. Please let me know if my current CPU will bottleneck the GPUs that I've shortlisted. If so, please suggest a cheap but good CPU.

If you're on a budget, I think you'll be ok with the 3870k. People get very worried about a bottleneck, but all it means is that you might not get quite as much performance out of it than is possible.

I'd pick up the GTX 950, it'll be a huge upgrade from the 7750 and is much more powerful than the 750ti.

If you did want to look at a new cpu, well you'd need a new motherboard and ram as well, as there aren't any better cpu's for...

If you did want to look at a new cpu, well you'd need a new motherboard and ram as well, as there aren't any better cpu's for the FM1 socket your current cpu's use. The Intel i3 6100 is a really good budget gaming cpu if you did want to do that, but as I said you'll probably be OK on the gpu upgrade (nothing to stop you getting the cpu / mobo later after all).

Thank you, this will save me a good amount of money as well. Also, a recent review on the DX12 showed that AMD cards have a good advantage over their NVIDIA counterparts. If that is the case, would you suggest an AMD alternative for the GPU? I have a cooler master thunder 600W as my PSU, so power requirement isn't going to be an issue, I think.

Well the current AMD cards around that performance level are the 370 (slower) and the 380 (costs more but also quite a bit faster). Also worth considering, come the end of June (29th I believe) AMD are launching their RX 480 gpu for $200. That gpu is supposed to be faster than the GTX 970, so at that price is a great deal. We don't know 100% how it really performs until we get real benchmarks of it on the 29th though, so just depends if you want to wait or not.

One other thing to keep in mind, AMD cards are more cpu dependent than NV in DX11 titles, so I think for older games you'd get better performance out of a GTX 950 / 960 than the equiv radeon, however as you say DX12 is a strong point so if you're planning on playing newer DX12 titles like AOTS then it'd be a good bet. Also I run an R9 280 on an AMD FX 8320 cpu and performance is fine in everything I've played. Just trying to give you all the info if you follow :)

Read about that RX 480, but every card launched in India is priced around 30% more than that in the US market, so it'll be way out of my budget. Considering DX12 titles might take a while to get mainstream, I'd rather stick to the GTX 950 then, hoping that Nvidia releases compatible drivers soon. Anyways, thanks for the detailed answer.

I have the same APU.
MY system build is:
APU A8-3870K 3.6 GHZ on Gigabyte A75-D3H
G skills (2X4GB) DDR3 1866 runs at 1921.
MSI HD 6570 DDR3 1GB (Dual Graphics with the APU)

My current solution until the near future:

1- I have overclocked my APU to run from 3 GHZ to 3.61 GHZ with good air cooling only (Over 20% performance boost)
2- RAMS are already clocked to run from 1866 to 1921
3- Disabled the integrated graphics of the APU. (The system will use 8 GB of rams in this situation, because integrated graphic is disabled).
4- You can sell your old graphic card and buy a new one
5- Bought EVGA SC Geforce GTX 1060 6GB (Nice small beast card 2017)
6- Tested on few Games with no bottlenecks - all games run at 1920x1080 60fps high or ultra settings except FEW games that are intensively CPU based games like Battlefield 1 as an example, but you can lower down graphic settings / resolution a bit and you will be OK.

conclusion:

1- AMD A8-3870K is not bad CPU at the moment, we still can play all older and many new AAA game titles well.
2- Other good cheaper Graphic cards than gtx 1060 are: AMD RX 470, GTX 970.


Game tested: hitman absolution, tomb raider, max payne 3, battlefield 1, skyrim, the witcher wild hunt
My future build is: Ryzen 5 1600 (6c / 12t), cheap good 350B am4 mobo + 16 GB of Rams.
