Esqueci de dizer que o meu i5 é Slakware travado sem Overclock
Amigo eu comprei o i5 supriu minhas necessidades. Se o preço baixar eu troco pelo i7 6700.
If you look to compare not just in speed performance but in real chip vs chip embedded hardcore features the i7 4790 still wins for the intel security restriction and software manipulation limitation and it's design custom capabilities such as high thread. Just saying.
Acho que o i7 já que eu não vou apenas jogar.
Estou na mesma dúvida. Aqui no Brasil o preço praticamente dobrou dos PCS e Hardware. Então tem que pesquisar muito para não jogar dinheiro fora, visto que a crise financeira no país está alta. Qual seria melhor comprar então?
Yeah I was starting to lean more towards the i7 simply because of the hyper threading.
Go with the 4790k, it'll be much better, for like, everything.
I can get the i5-6600K for $249.99 but I can also get the i7-4790K for the same price. Should I go with Devil's Canyon or should I go with Skylake? I'm going to be upgrading from an 8320E so either way it's going to be a huge upgrade for me.
The i5 can over clock highier than what the i7 can. That is the advantage of upgrading.
well it's still i5 vs i7. 6700K barely does anything against 4790K. Even the 950 is close enough to 6700K that people don't want to upgrade. So of course Devil's Canyon i7 will beat a next gen i5
seems like i5-6600k doesnt do a shit compared to i7 while its useing 14 nm lol
I7 winner
