What about cooling? Are you planning on overclocking?

This. i5 is old, and an i7 isn't that much more expensive. It's worth the extra cash.

How exactly is the i5 old?

They were introduced at the same time I think...But someone was right, you have to know what resolution you'll be gaming at. If you're gaming at 1080p or less, tone down the gpu a bit and with the money saved, get an aftermarket cooler or something (if you're getting an intel processor with a K at the end, which means it can overclock easily)

Yes ,  that's why both cpu's  I'm looking at are unlocked , in the original build spec for cooling I added a corsair H100 wk set to the list, the reason i7 came into it , I  matched the i5 -3507 K CPU to the Gigabyte G1 Sniper 3 MOBO pemalite said they are different sockets , and suggested the i7 3939 k but now i know he mixed up his Mobo's so now I'm leaning toward either the i5-3507K  or putting a i7 3770 into the  G1 Sniper 3  , also I went for the Corsair TX850 V2 PSU as it is aimed at OCers with plenty of watts with minimal fluctuation and it ties in with trying to build some longevity into the build as I intend it to hopefully last a fair while , with just some future additions like extra gpu etc when and if needed .

It's not diminishing returns if it lasts you 6-7+ years so you can hold off upgrading the Motherboard and Processor and maybe the Ram again.

Next generation consoles are almost upon us, so system requirements should take a bit of a jump, especially with the rumours how they will be more heavily threaded.

i would spend extra cash on a modular power supply the ax850 if you can find it on sale or the tx850m which is fairly new.I would have sid the h100 is over kill but given ivy bridge runs hotter it might be needed i get a long with an oc in the 4.6 range with a hyper 212+ and 2 fans and stay 60c

GRAPHICS CARD - ASUS GTX 680 Direct CU II TOP this is the O version right with the 1137 base speed should be a beast i have not seen any in stock at a sane price so i ended up going with the PowerColor PCS+ 7970 VORTEXII and its base clock to 1100. it will be a bit slower than the asus but it was cheaper and in stock and form what ive read you can expect more oc room, though i think the asus will still out perform in in the range of 2-3%

the mobo is awesome --- i want/was thinking of getting one :) this one right http://www.newegg.com/Product/Product.aspx?Item=N82E16813128552

Ram is good, though gains above 1600 speed are not fantastic, see tomshardware and anandtech for more details  (I alo favor 16 gb of ram since its so cheap, but i run servers off mine too)

i would say a crucial m4 or samsung 830 would be the better SSD i have both and love them


what case are you using?

i thought he was looking at this mobo http://www.newegg.com/Product/Product.aspx?Item=N82E16813128552

looking for quite or gaming? if quite id recomend the corsair 550D 

how much do you want to spend on the mobo

get the OC asus 670 direct CU II techpower up hads a nice review on it http://www.techpowerup.com/reviews/ASUS/GeForce_GTX_670_Direct_Cu_II/

cpu as mentioned above are you not going to overclock  thats a good one if not maybe prior gen (sandy bridge) but you loose pci-e 3.x spec by going sandybridge and a few other things

PSUs spend more to go modular i did not on my first build and regretted it, but have since rectified the issue and 750 for a second card unless your looking at 7850 or less in terms of cards 

RAM - dont buy patriot is all i can say i had to rma an rma from them. corsair/crucial never had an issue

ssd the samsung 830 or crucial m4, 128gb if you can find them for 120 or less (99 bucks on newegg for the m4 right now) or 256 if you can get it for 220 or less 

Yes it is that Mobo ,  the problem was I was mistakenly told in the thread that it was a 2011 socket Mobo and the i5 3570 was  socket 1155 so thats where the confusion comes from.
