OK. so after plenty of help from the guys here (much appreciated) ive come to a near conclusion with my build

before i begin, i am not changing to an i5/i7/ivy bridge/haswell so dont suggest it, nor am i intending on changing the graphics card as EVERY time i list a gpu someone says "why dont you just buy [this more expensive, next model up]" . i have settled for these parts for now. im more thinking about the future

Primarily i will use this pc for gaming, the higher settings the better but ultra max isnt necessary

Also i use the pc for programs like cubase and fruity loops

aside form that just general web broswing/email

no rendering or photoshop

CPU
FX 8350

MOBO
Gigabyte GA-970A-UD3 AMD 970 SB950 ATX Socket AM3+ DDR3-2000 USB3.0 SATA3 RAID 1394.

OR

GIGABYTE 990FXA-UD3 AMD 990FX SB950 ATX Socket AM3 DDR3-2000 USB3.0 SATA3 1394 eSATA RAID

GPU
Gigabyte GeForce GTX760 2GB OC
• WINDFORCE 3X Cooling system
• Integrated with 2GB GDDR5 memory
• 256-bit memory interface
• Features Dual-link DVI-I/ DVI-D / HDMI / DisplayPort
• BASE:1085MHz / BOOST:1150 MHz
• System power supply requirement: 500W
(should also mention it is a pcie v3.0 card)

RAM
8gb Kingston ddr3 1600 (4gb x 2)

HDD
1TB Segate

PSU
Antec EA750 'earthwatts' 750w

okay so now you can see what general direction im heading in, heres what i wanna know

i have read very good things about using 2x SLI Gtx760s so in the future that may be my next upgrade perhaps once the card drops in price a little more.

the GA-970A-UD3 mobo only has one pcie x16 v2.0 slot so the option of sli goes out the window, where as the 990FXA-UD3 has two pcie x16 slots and is sli compatible BUT is still only version 2.0 .. is this likely to cause a bottle neck once i go down the sli route??

would it be better to just go with the GA-970A-UD3 and use one gtx760 and wait until amd comes out with something that supports dual pcie 3.0(how ever long that will be?)

and also with the powersupply for sli

http://www.guru3d.com/articles_pages/geforce_gtx_760_sl...

here they recommend when running one gt760 that you should have a 550w psu and for each card you add, another 200w should be added

that said does this mean that 750 watts is the bare minimum to run these cards or does that take into account power needed for the entire system (so will the antec be good enough or will that also need an upgrade if i go sli) and yes ofcourse a 1200w would be great. but thats definately not in my budget right now

so short review

Should i get the mobo that supports sli to plan for future, or get lesser board and wait for a next gen amd with dual pcie x16 3.0 (will that happen?)

Will Sli suffer from pci 2.0 (from what little info i can find the answer is no but can someone else verify this)

Will the 750w antec be sufficiant for sli

thanks in advance
i know its yet again a mammoth post but i think once i settle this, that will be me done for a while, this whole process has been a time consuming hair puller to say the least.

Thanks!
Liam

The future is single cards. SLi andCF is mostly not a good idea unless you do a lot of multi monitor.

Also, modern graphics cards are nowhere near saturating the bandwidth provided by PCIe 2 x16. A guy I knew benchmarked a GTX Titan on PCIe 2 x8, and got close to full capacity results.

BTW, since this system is such a monster, please check this out,

Folding@Home is a "distributed computing" project. It lets users "donate" their unused computing power to help disease research in critical areas such as Cancer and Alzheimer's. Do the world, the future, and maybe you yourself some good by at least checking it out. Link here. http://folding.stanford.edu/

Moral things aside. Many performance enthusiasts love to compare how well their PC is by showing their points tally for folding. Tom's Hardware has its own team right here! Come in and comment! http://www.tomshardware.com/forum/id-1580785/folding-ho...

so you would recommend the lower mobo GA-970A-UD3?? i mean in terms of money, savings are fine with me i suppose i can just do a mobo upg later, wondering if the less one will still give me good over clock ability and longevity

i like that you called it a monster however, made me feel like iv made a good choice haha! i will check out your links :) 

thanks

also, how much bandwidth is folding likely to use, as im not on an unlimited plan

Please ask in my second link!
Many of the masters here are in limited internet.

Yes definitely go with the cheaper board

By the time you run into problems, there will be better faster boards.

The difference between the boards is $30... Personally, I'd pass.


What do you mean, "not on an unlimited plan"?

as in we have a limit of 50gb per month

Well, it varies on how someone setup the client and how long it takes to fold a packet of data called a Work Unit (WU).

Each WU varies in size and how long it take to process.

Some WU's can be less than 5MB in size but takes a long time to fold while others can be 100+ MB in size and fold very quickly.



So while I cant answer how much bandwidth it'll actually use, (as it's a always changing target and different for everyone setup), I can say it's very limited when you setup the client in a way that only takes small WU's (5MB and smaller).

So if you only fold one WU a day for 30 days (which there is a way to setup to limit the amount of WU's per session on top of the size of WU), It'll be a peak of 150MB used "if" each WU was exactly 5MB.


Hope this answer your question to some extent. :)

yeah sorry i must have missed the notification email. i came across an extensive benchmark of my gpu which actually had a becnhmark on folding and it said this card isnt very good at all for folding, gaming yes but folding no

I have been extensively warned against proposing other GPUs to you, such as the folding monster HD 77X0 cards, so I won't... Jokes aside, any high end monster card (like yours) is a great folder, and any and all contributions are extremely welcome.

Oh, and also, how much internet do you usually use per month? And is it 50 gigs down only or 50 gigs download and upload? (easy way is to tell me what your provider and plan is.)

However, my primary purpose here is to configure the absolute best system I can for your uses. Do you have any more questions?

haha i wont being going ati gpu .. heard bad things.. plus its a gaming pc and thats what the 760 is built for :p  and we are actually using more then 50gb a month.. we have upgraded to a 100gb(up/dl combined) plan which wil take effect next billing cycle, but i think we will use the most of it each month, however the other guy who posted said that it might be around 150mb per month which is nothing, the only other problem is possibly leaving the pc on as we pay rent including power and recently the landlord has begun to point out we r using more power (i havent even got my new pc yet wont be for another 6 weeks)

i feel like this has been hijacked to a folding thread lol however i feel like the system i have finally chosen is the right one regardless as i no longer intend to go sli so psu and mobo isnt important uintil my next upgrade

plus im from new zealand so i doubt you'll know the provider, but it is slingshot

i will give folding a try once i get the computer as id be glad to help.. but a quick glance at the thread does make it look like a friendly war on who can crunch the biggest numbers in the least time haha


i have thought about getting an ssd but they are just so damn expensive im literally right on my spending allowance while only having a win7 trial! i mean really i was only going to spend like i think 900 in the beginning and now ... its looking closer to 2000 haha... iv been sucked in to the world of pc building... AND IM HOOKED

so far (lol)

build is

fx 8350
GA-970A-UD3
750w antec earthwatts
8gb (kingston) drr3 1600
1tb west digital hdd
BitFenix Ghost
22x dvd writer


$1200

120 gb ssd is around 150
then the gtx 760 will cost me almost $400
The OS ... 120 - 200 depending on home premium or professional
and im being sucked into the overclocking world too so a corsair h100i is on the books which is 200
nzxt lx fan controller 109
sensei steelseries fnatic mouse 129
and most likely a new monitor, which could cost anything!!

and after all the research and talking and different types of builds iv realised... that i actually love computers, hardware, software, tweaking etc etc. and all these tech reviews and unboxings on youtube, custom casing/waterloops

i want to start a career revolving around them! but i wouldnt have the slightest idea where to start. (maybe you have some advice there???)

now we r really getting off topic haha..

Don't worry it's your thread!

And the folding thread is a couple of giants cocking about because there is nothing else to do. Really, they are great guys who will answer any questions.

Now to the important stuff, I can do some cost cutting for you...
$400 for a gpu oh my word new Zealand... No better price?
An expensive mouse is stupid
A case is but a box to put your parts in, pick a cheaper one
OK I need to research nz prices...

its very costly here ( but after currency exchange its kinda relevant although it does end up being a litle more expensive)
actually the gpu is $529 here lol .. its 339 in austrlia which im getting my cousin to bring over, after currency exch makes it about 380 nz
as for the mouse i do a lot of fps gaming so the increased dpi plus a couple of extra buttons cant go astray (im not looking for one that has 50 buttons and transforms into a yellow camaro XD)
the case well i wanted one with good cooling options which this one has plus its very subtle.. most of the high cooling cases look like they fell outta space. so the ghost is functional and aesthetically pleasing :)

oh cool! :D  haha actually, i am buying it off trade me from someone in mt eden who builds computers

all iv really done is research on components and sent him emails to tailor to my needs, i actually had a look on pc parts picker and if i had hav built it myself it would have been about 140 bux cheaper haha .. but i suppose its a little extra to pay for 18 months warranty

problem is, because i hit buy now im pretty much committed to buying something now .. shoulda done a bit more research first.. but i was to anxious for a new gaming machine and really hes pretty fairly priced anyway (considering the terrible prices we have here compared to the likes of usa etc!)
