Pc choice dilema

Ah i come across a problem everytime i wanna buidl a pc wether its last minute holidays or just being an idiot and spending money on another item i dont need. 

So here i am again asking a question this time i cant decide, i have so far however saved £900 towards whattever  build i see good il be looking t spend about £1800 which is 2789.64 U.S. dollars. However im stuck between choosing an i7-3930k build or wether i should go 3570k in either an atx form factor or itx. ive really been liking the thought of an itx but the power of the 3930k and the atx meets somewhere in the middle. all i ask is a system which can play mmo's,rpgs, and rts's being god enough to record them and possibly stream too with a big performance hit. so my question which should i go for? with the atx and itx i could happily go wth gtx 680's and 3930k id probs get a gtx670 and add another later. all these options would be cooled by a h100 and have mushkin redline enhanced ram all cpu's at 4.5 ghz (or as close as i can get and still be cool as possible. 

So heres my problem which should i go for? and would the itx asus z77 deluxe-1 itx be good enough for this stuff. because i really like the idea of a nice powerfull but sleek and small uild

That's overkill, Ive never seen an MMO, RPG or RTS max out a mid-end rig. Go with an i5-2500K, get the H100, a 560-Ti, a Z77 Deluxe-1 motherbaord, some good RAM and a 750W PSU from a good brand. For streaming just get this thing: http://www.amazon.co.uk/gp/product/B007SRYAPO/ref=oh_details_o02_s00_i00

But... But... i like overkill means if something does come out i can play it maxed 0.0

I also like insane set ups but think of the heat buildup in the case if you went with those components.

He can always liquid cool everything.

 

It is definitely an overkill system. Save your monney and get an i5 because I really doubt getting a hyperthreaded pc for rpgs is a good idea. just a lot of waste
