I was thinking to change my fx 6300 for a i5 4570 for 81 bucks I don't know if it's a good idea it worth? There're is other budget option ? Sorry for my English greetings from Mexico
The i5 performance is way better: http://cpu.userbenchmark.com/Compare/AMD-FX-6300-vs-Intel-Core-i5-4570/1555vs2770. You'll also need a new motherboard and possible RAM.
Amd cpus/motherboard is totally different to Intel cpu/motherboard. If you want to change the cpu you will also need a motherboard for Intel lga1150 cpu. H81, B85, Z87, Z97, etc
it worth? There're is other budget option ? Sorry for my English greetings from Mexico
