imo,
it the i7-5820k build wouldnt b much diffrent with the i7-4790k build in term of gaming performance,
myb just 1-5% dffrent on CERTAIN games,
on future proofing also will not make much significant diffrent,
unless if u have 6.5k budget, then it will b another case

aih?? r u building ur own pc?
have asked recomendation on any thread?

ur pc shud handle current gaming gud,
just nid to adjust the setting to get smooth gameplay,
upgrade to GTX970 gonna b a huge boost,

aihh i didnt notice this comment,
sorry to say bro,
u r partially right,
if im restricted with budget better i spend on xeon as it will run on cheap mobo n cheap PSU,
so the last bill would be cheaper than the i5-4670k as it nid powerfull mobo, power PSU n xtra cooler to juice it up

if u talking about i5, even the i5-4440 would perform moreless the same with the i5-4670k on gaming

so as minecrafter said, better future investment on xeon (or any cpu than have more thread)
