My current PC has 6 years, I need the new components to use in the next 5 years (In the last 2 years, I don't care about run the games ate low settings... I only want run them without breaks).

I think about this components:
- Asus M5A97 R2.0 (86.04€)
- AMD FX 8320 (122€) ou FX 8350 (149€), do you think the diference of 27€ has justification? Any Intel for the same prices withe same perfomance?
- Kingston DDR3 HyperX FURY Black 8GB 1866mhz (70€), 1600mhz or 1866mhz? This board/cpu is enought to use the 1866mhz?
- Sapphire DUAL-X R9 270X OC 2GB DDR5 (152.09€), this graphic card is PCI-Express 3.0, I know will lose same perfomance, correct? A lot of them or only a little?

All prices is from Amazon.es

All suggestions are welcome, thanks for your time.

Here is a build that comes close to your budget. The prices are based out of the UK only because PcPartPicker didnt have an option for Portugal.

I included a power supply because That power supply is unknown to me. The power supply is the most important part of your computer so the unit I included is a top tier unit and will give your excellent reliability.

I also included a new CPU cooler because the one you have now doesnt look like it will mount to newer CPUs.

Let me know if you have any questions.

The Motherboard you listed is a decent AMD motherboard, I have one myself, its pretty good. and the FX 8320 is a good chip, I wouldn't bother with the 8350 if you are comfortable overclocking, the 8350 is literally the same chip, only the factory overclocks it for you.

The build I listed however will generally outperform the AMD build you were looking at. Especially in gaming, the Intel i5 is far more efficient.
