I5-2300 vs i5-2500 + mobo importance?

Hi guys,

I'm building a list of parts for my new pc and when i count the GFX (HD6790), RAM (2*2GB ADATA 1333), PSU (500w bubalus) and case im only using like 40% of my budget which is making me think of getting an i5-2500 (not the k version).

Is there a big difference in motherboard performance or is it mainly just some having different extensions (USB ports etc)? If no big difference then what (cheap) boards would you suggest to go with 2300/2500?

Is there much difference beside the non-K version 2300 & 2500? Or I can save the extra $32 and get a 2300 instead? I won't OC~

with a i5-2300 maybe i could get a HD6850 instead of 6790~

thanks for any info

current ideas
2*2GB ADATA 1333 RAM
GPU: gtx 550ti / HD6790 / HD6850 (pushing it...)
CPU: i3-2120 / x4 955 / x4 970 / i5-2300 / i5-2500 (last 2 pushing it...)
PSU: bubalus 500w (cheaper) / corsair 500w (more expensive)

Well it depends greatly on your budget, what is it by the way? I am also building a computer at the moment and came across the same question, and I'm going with the i5 2500k. You want to get a good cpu for your computer and the extra $35 is worth it in my opinion. At first I wasn't so sure about overclocking, but i figured I should spend the extra $10 (from the 2500 model) for the option in the future.

my plan is $470 without HDD/SSD/peripherals (dont know if i will actuall get ssd). so $470 for psu, cpu, gpu, mobo, ram, fans...im not missing anything am i? :x
so the i5-2300 isnt a good cpu? the difference between 2500 and 2300 is bigger than the difference between hd6790 and hd6850?

what is your budget? :o

my budget is around $1000. I'm new to builds so I'm not really the best to ask, but the difference between the two processors (as far as I can tell) is the 2300 has a max of 2.8Ghz, and the i5 has a max of 3.3Ghz. If you get the "k" model you can overclock it and make your computer run faster, but when you're on a budget this may not work. Check out this website that I was referred to by aznshinobi: http://www.squidoo.com/electronicandmore#module14708687...

There is a pretty good $400 build on there. Oh and about the motherboard. Motherboards can limit you on overclocking, sli/crossfire, and ability to add new memory and such. So you should do some research on the board you are looking at and see if it matches what you want to do. Personally I'm going with this board: http://www.newegg.com/Product/Product.aspx?Item=N82E168... because it is good for gaming and gigabyte is a great company.

I hope my rambling didn't confuse you ;)

2300 is the entry level sb i5. 2500 is the top of the line i5, locked version. 2400 is the middle one, take a loot at this month's $600 system builder's marathon build.
the better cpu you get, the higher the minimum fps would be. however it gets to a point of diminishing returns when you get to cpus like 2700k/3930.
the 6850 is better than the 6790, more power efficient. it's the most powerful gfx card with a single pcie connector.
don't skimp on psu.

Hmm I don't have any plans to OC or have more than 1 GFX card. The only thing is possibly increasing from 2*2GB RAM~
The place I'm looking to buy sells the 2400 for the same price as the 2500 so it's not really a consideration.
this will only allow for 2 sticks of RAM right? :x http://www.360buy.com/product/555296.html -- at the back...it's only 2 USB ports? There's 6 similar sized >_<

let me get this straight. you want to build a single card, non-oc cpu setup?
the h61 cipset only allows for 2 ram slots, has less ports (because the h61 chipset has less pcie 2 lanes than others). h67, p67, z68 allows 4. can you afford a micro atx z68 board?
if you do get an h61/h67/p67 board, make sure it has b3 revision. b3 rev. fixes the earlier cougar point sata port degradation bug. z68 boards should have b3 rev from the factory, check those too. also try to get 2x 4 gb dual channel kits.
get the core i5 2500 since it's similarly priced to the 2400. try to get a 6850, if you can't, then the 6790. get a good 500-550 watt, 80+ rated, active pfc psu. corsair, enermax, antec, seasonic, xfx are some good brands. check the power supplies forums for more info.

The cheapest z68 I can get is 72uk (maybe $100)...why do i need to pay so much for a mobo...part of the reason I was saying a 2500 or HD6850 was possible was because I thought the mobo would be cheaper `-`
is it me or are the 67s crap?
$75: http://www.360buy.com/product/498022.html
$90: http://www.360buy.com/product/365307.html

neither supports my keyboard/mouse setup with a single PS/2 connector...

cheapest h67 has the same issue & similar prices: http://www.360buy.com/product/498022.html

yes, single card, no-OC.
why 2*4gb?...overkill, no? when would i need 6-8G RAM? :o  not only that but it also pushes my budget further when it was already at limit (or apparently over with mobo prices...) by having either 2500 or HD6850

A guy at work who builds his own pcs said bubalus is a good PSU...why have no western sites reviewed them =(

add your OP from the previous thread to this thread's OP. it will provide more info on your preference.
i've never heard of bubalus psu or colorful motherboard. perhaps they are specific manufacturers to your region.
if you're looking for 'the cheapest', you won't find quality components, features, ports etc. those components are made by cutting corners as much as possible.
the asrock h61 seems to be the best one among the ones you linked. make sure it has b3 revision.
4 gb is adequate for now. but if you use up all your ram slots (2 in the h61 mobo) you might not be able to 'add' memory without 'replacing' your existing memory in the future. still, 2x 2gb is enough.
i read your previous thread, 6770 is enough, 6850 is more than enough at that res. but the games might be cpu bound, so a 2500 will be good.
as for psu, get a known brand even if it costs a bit higher. that thing powers all of the components in your pc. a cheap, badly built one can kill your pc and hurt you (not joking there) any time. they also tend to degrade more quickly than good ones. make sure your psu has at least one/two pcie connectors. the 6850 requires one.

you should go to your motherboard company's website and search for rams tested with that motherboard. look for it's qvl list.
also run memtest and prime to find out memory errors.
115v is american standard and 230v is asian standard iirc. if you use wrong voltage with your wall socket, you could damage your psu, subsequently your system.

the build looks okay... psu... i don't know, google it's review.
will you be too over budget if you get the asrock h67 mobo in the 3rd link?
if you look at the bottom of that page, in the chipset comparison table, you get sata iii (6 gb/s) ports, usb 3, 4 ram slots with h67. just make sure the h67 mobo has b3 rev.
can you check if the motherboard supports the ram you chose?

PSU?...everyone has been saying get a branded PSU like corsair...it says 80PLUS >_<
adding the h67 is ok...although its already way over budget =( only reason im agreeing to it is USB3 :p 

I have to check if the mobo supports the RAM?...its not a case of 1333 for some, 1600 for others?...

i googled the corsair cx series. it seems like the cx series is corsair's entry level psu series and are a bit hit or miss.
check jonnyguru.com or tom's power supply section for cheap, good quality psus.
like antec earthwatts series, neo eco series so on.
h6x chipsets support only ddr3 1333 ram, so getting 1600 ram might be waste.

NEO ECO 450w should be ok for my system (1 cpu, 1 gfx card, no OC) or I need the NEO ECO 520w?

Yes I mean as long as I choose 1333 instead of 1600 shouldn't it be fine? Some 1333's only work with certain boards? :x

edit: someone is selling a GTX 280...the R6790 is much better than it? I can't find a chart with both of them to compare

i am amazed at how you keep finding these stuff.
ddr3 1333 for the h6x chipset is fine.
the 6790 requires 2 pcie connectors. here's a review:
http://www.tomshardware.com/reviews/radeon-hd-6790-bart...
the neo eco 450w or 520w .... google their reviews and check their load performance and if they'd support your chosen components. check toms power supplies section too.
if you absolutely know what you're doing, you can run a radeon hd 6850 (which is a 127w card, more power efficient than 6790 which is a lower tier but 150w card) off an antec earthwatts 380w psu. but you'll have to be absolutely sure about what you're doing.
if it's cheap you want, you can get a very cheap build solely based on price.
for example: intel pentium g860/core i3 2100, asrock h61 b3 rev mobo, 2x 2 gb ram, radeon hd 6770, 400w 80+ rated psu with at least 30A (continuous) on +12v rail. you can go even cheaper with amd athlon ii x3 445 or phenom ii x2 560 b.e., cooler master hyper 212+, 780/870/970 chipset asrock/msi/gigabyte micro atx mobo with 2 ram slots, same ram, gfx card and psu from intel build.
here's a graphics card hierarchy chart where you can compare gfx cards:
http://www.tomshardware.com/reviews/fastest-graphics-ca...
gtx 280 and 6790 are in the same tier. i can't comment on gtx 280 but i know that the gtx 280 is old gen, directx 10 card while 6790 is latest gen (soon to be replaced by 7000 series) directx 11 card.

I can't find a 450w review, only 520w which wasn't that helpful (doesn't say what specs it was run with). I found this toms review of PSUs and then the only one I could find was the last one...you have the same problem with that review though when it doesnt say what kind of spec is used for testing~

what do you mean about sure of what youre doing? :x its not just a case of plug it in & start using? :s

running a 6850 off a 380w psu is quite risky. you have to carefully select the psu so that it can properly power the system without causing instability and damage. you have to keep an eye on the other components you use - hdd, cpu fan, odd all use some power. i personally would never run a 127w card off a 380w psu, i'd rather have a good 450-500w psu do that - just to be on the safe side.
