There's no issues, but I don't see a motherboard. without one everything else will be useless.
Might I recomend that unless you plan on shelling out for a new CPU in the next few years you go with the I5-3570k, or perhaps the i7-3770k (The only reason I can see for going with the i7-3820 is if you plan on getting a new cpu relatively soon, so need the 2011 socket).
The 3770k performs just as well if not better than the 3820 and has an unlocked multiplier (as all k chips do) so has the ability to overclock. IMHO there is no need for to spend the extra $90 on the i7, as an overclock 3570k is just as good, in fact when gaming you won't be able to tell the difference.
Spend the money you save on a better graphics card or a solid state drive.
If you give me your budget I'd be happy to make suggestions.
I agree, get a 3570k and overclock it. Get something like an H100i water cooler to make up the price. For a motherboard I recommend something like an Asus P8Z77 V, if you're not on a budget maybe a Maximus V Extreme
I see... Ok thanks for your answer. I'll take your advise on the 3770k. About the motherboard, I really dont know a lot about motherboards so if you recommend me one i'll really appreciate it and about the gpu i think that is a great gpu the only one that I know that is better than that one is the gtx 690 and I can not afford that, but still thank you for answering.
