Be aware you'll have to buy a Z77 motherboard for the 3570k (Not have to, but its nice to have). I would go for the i5, as it'll be more suited for your uses. Really, the 8350 is better in some applications, but it does require a little bit of tinkering and it does really matter on what you do. I'd go for the 3570k.
If you buy an FX 8350 you'll need a new motherboard too.
i have no lga 1155 motherboard i am buying new pc
so now i am using my old c2d e7500 with asus lga 775 mobo
so if i buy amd then i will able to buy new corsair 1600mhz ram
if i buy i5 i am not able to buy new but if i5 is better than i will buy i5
i have 4 gig of ram not know company name but gives me 6.5 (good or bad idk) windows experience index
so i am highly confused between them about it
so help me i see some of videos about amd fx8350 vs i5 3570k
the amd wins and give more fps in multitasking games like crysis 3,2 and other and i5 give single threading better performance idk about what is this and which one is better overclocking?
