With such a big budget i always like to advice people to get a sli or cfx setup with good cards because the gpu power is the most important part of any gaming computer...there is no reason at all for you to go with the i7,so save money there and go with the i5.(also save money on the mobo if you can,invest all the saved money in getting more gpu grunt),i have a hd 5970 and as you can see in this bench :
AnandTech - Bench - GPU12 performs slightly(2-6% in some games) better than the 660ti(in games that work well with cfx and of course not in those that dnt work too well,like arkham city),my point being that even with my card when you enable all the bells and whistles in almost all new dx11 games at 1080p,the results are not the most spectacular.i don't expect 660ti to do much better considering it performs very close to my card.so i am advising you to stop spending lavishly on things like mobo and cpu(a big no from my side to the i7) and even the cabinet(of course you may not want to sacrifice those delicious looks and the accompanied breathing space).
As for the oc part,the v6gt is a total disaster right there,even the more expensive brethren of it the V8 loses to the lowly 212 evo(only rs 2200) when both are running at high fan speed,here :
PCSTATS - Error Warning ctrl+F to find the 212 evo and the V8(and please check that the results you are looking at are for 'high' speed),so fact: V6gt is not a vfm product and can only be recommended for it's looks.as far as i am concerned,with that rig,i am sure you want to oc the cpu to it's limits,that means pushing the max volts,and feeling the max heat...(and trust me you don't want that kind of heat in the indian summer times),maybe coolers like the evo will suffice for the winter ambient temps(just maybe,the ivy's run notoriously hot),but its not gonna be smooth sailing for you the rest of the year.My Advice?Invest in a water cooler like the antec kuhler h20 920(i also have this baby),will tell you more about the merits of this particular cooler if you are interested in it(do i sound like an antec sales person right now?).why water cooler and not a big-ass air cooler in the same price range?well because the air cooler will be
big-ass, apart from it possibly snapping your mobo in half(lol no),they are too cumbersome,bulky,and no air cooler costing somewhere in the price range of the earlier mentioned wc cooler beats it.so there.(i personally use it,take it from me).and as boo said a good alternative to thunderfx would be any usb sound card.
and seriously alpha,what is he going to do with 32 gigs of RAM?nothing in his usage warrants that much amount of ram,i would dial it down to an even 16Gb(and you can easily clock 1600 vengeance's to 1866+,only a matter of +ov'ing,and these baby's can easily take +0.2V with those monster heatsinks on 'em.)
so the rig
I would personally buy(if you handed me your money,because my advice's worth 1.3 lakh,you just don't know it yet)would look like this:
i5 3570k- rs. 14,893(at flipkart)
antec kuhler 920- rs.6900(Also at flipkart)
ASUS P8Z77-V PRO ~16000/- OR GIGABYTE-Z77X-D3H ~13000/-(same as aplha,although i would prefer going for the gigabyte one,you save 3k in the process)
G.Skill RIPJAWSX 8GB x2 1600MHz ~5414/- (easily oc'ed if you want more speed,although it will be totally useless,take it from me,i also oc'ed mine cause i am a oc freak,didn't yield anything at all)
HP / ASUS (boxed) optical drive ~1100/-(again same as aplha)
Seagate Barracuda 7200.14 1TB ~4200/- (add more later)(same)
OPTIONAL SSD(CURRENTLY)-now this is probably going to cause the most controversy in my post,because i am advising you to not buy a ssd in your initial buy,you may want to add this later,why?because it costs a lot and all you will get right now are faster booting times,general increase in OS performance and decrease load-times in games(and you won't have much space to install games in anyway),but let me tell you that my load times with a 1tb 7200RPM WD green HDD are already so low ,i don't really think that thats an aspect of my computers performance i want to or ought to increase.so really many ppl will not agree with me here,but i am telling you,even if your budget is 1.3lakh i don't think you should spend so much on such a luxury.
2 x gtx 670 2gb gigabyte windforce 2x in sli - 2x 26964= rs.53,928
