Ok to begin with this will be my 2nd desktop build trying to keep it at around $1700 but i want a 5970 on it.

This is what i have came up with so far first one is I5 build and second one is I7 build

http://secure.newegg.com/WishList/PublicWishDetail.aspx...

i was curious of what you guys think of these builds, what you would do differently, or go a entire different direction altogether.



APPROXIMATE PURCHASE DATE: in the next 2 months

BUDGET RANGE: around $1700

SYSTEM USAGE FROM MOST TO LEAST IMPORTANT: gaming, movies, music, trying to make a system that will last quiet a while

PARTS NOT REQUIRED: no need for speakers or mouse or monitor and i am a college student so i can get windows 7 cheap

PREFERRED WEBSITE(S) FOR PARTS: newegg but willing to try other places

COUNTRY OF ORIGIN: USA

PARTS PREFERENCES: by brand or type Intel

OVERCLOCKING: light over clock probably to 3.2ghz on the I5 build or 3.33ghz on the I7 build

SLI OR CROSSFIRE: no

MONITOR RESOLUTION: 1680x1050 will be upgrading in the future

More about : 1700 build

No need for x58 if you're getting a 5970. By the time you'll need 2 of those (which probably won't be unti next gen consoles come out) much better GPU's will be out.

Go with a i5-750, asus usb 3.o/sata 6.0 board. No need for xfire as explained above.

CM Hyper 212 Plus for a HSF

Corsair XMS3 DDR3 1600 7-8-7-20 for RAM.

PSU wise a 750TX will run a 5970 system fine, but the Seasonic 850W is same price atm, so a better buy.

You could probably combo a buncha stuff and fit a new 1920x1080 monitor and SSD into that build for $1700.


I'll give it a try after lunch.

so why does everyone prefer the I5 to the I7s ?

It's cheaper. Seriously. The i5 is just as good as the i7-860 and i7-920 in gaming, but it's cheaper price tag allows you to spend more on the GPU, which is more important for gaming.

I'm a noob and I've been having a conversation about this in another thread. From what I understand, it comes down to the value of the i5-750 from a cost/performance standpoint.

The cost to build an i5-750 machine is typically cheaper by $100 or more due to:
- The i5-750 chip is cheaper than the i7-920
- The 1156 mobos are typically less expensive than 1366 mobos
- The 1156's 4GB of Ram is less than the 6GB for 1366
If you're a gamer, since the two chips have a similar performance on gaming benchmarks, the money saved could go towards an upgraded GPU.

If you're not a gamer and want it for more CPU intensive tasks such as video editing/encoding, then I have been told that the i7 920 and i7 860 are better options due to their multi threading capabilities.

Oh, and the 1156 chips use less power than 1366 chips, so you could save a bit of money on your electric bill if you go with the i7-860 or i5-750.

The drawback that some have with the 1156 is the possibility that it's not as "future proof" because intel may not release future 6 core chips on the socket.

EDIT: Ha, I guess MadAdmiral managed to say the same thing using a lot less words! ;)

well see i want to future proof as much as i can on my budget which is why im trying to get good quality parts some of which i might be able to reuse. what build would you guys create with that in mind ?

x58 is futureproof until next year. Intel moves so fast w/ new sockets and Architecture that anything you buy from them is outdated in a year.

So unless you plan on upgrading to a $300-$600 i9 w/in the year, you'll need a 22nm mobo next year.

If you want a mobo and socket that'll last you several years, only choice is AMD.

the new core i9s come out in marche from what i have seen various places and uses the same socket as current i7.

and as for amd they always seem to be behind the curve as far as technology goes which i dont really like.

yes sandy bridge i9s are gonna be out first half of 2010 according to Intel on socket 1366.

22nm sandy bridge CPU's early next year. These will be a new socket type.

ok so does amd have more bank for you buck over long term than intel does it what i think your saying. but how do the next gen amds look like will they even hold a candle to the coming generation intels ?

On the overall choice of platforms, I'd say that:

if you are going to stand pat with this system for 4 years, no upgrades, go i5 / 1156
if you are going to do a CPU / GFX upgrade after 2 years, go i7 1366

As to the power issue......it's non issue ..... at MAX draw we're talking 35 watts difference....so say you running prime 95 @ 8 hours a day ....

35watts / 1000 watts per kw x 8 hrs x 30 days per month x $0.10 / 0.85 PSU efficiency = $1.05 per month

"In real life", at 8 hours a day even, you're talking much less.

MoBo - Either way, I'd move up to one of the Asus Boards with SATA III and USB 3

Memory - 3 GB doesn't fit with a $650 vid card....6 GB of DDR3-1600 CAS 7 is cheap @ $179
http://www.newegg.com/Product/Product.aspx?Item=N82E168...

Case / PSU - With a dual GPU and OC, I'm thinking you wanna move up a tier in PSU. That means a Corsair HX, Antec SG-850 or CP-850 or Seasonoic MD12 (not the S12). The Antec 1200 / CP-850 combo will save you $50 and be a substantial step up in cooling ans well as PSU performance.

Hard Drives - Check out the performance charts and pick whatever 500 GB per platter drive performs best under your usage patterns. The WD Black 2 TB is a good choice but at smaller capacities, you are limited to the Seagate 7200.12 or the Spinpoint F3. The 7200.12 excels in gaming, multimedia and pictures whereas the F3 wins at music and movie maker. See the comparisons here (copy past link in manually, link won't work in forum):

(http://www.tomshardware.com/charts/2009-3.5-desktop-har...[2371]=on&prod[2770]=on)

Heat Sink - For $3 more you could have a Prolimatech Megahalems ... easier to install and better performance

use 1 fan for moderate OC's like your talking about.....add a 2nd fan and one of these for serious OC's

Wow, that's very helpful! I'm trying to decide between the i7 860 and i7 920 myself (with my 1156 build being only around $20 cheaper) and I have been wondering what the cost would be for the higher power consumption of the 1366 builds. Thanks!

I've been teetering back and forth, so this is good info.

well i think i might try a build with a 5870 so i can put more money into a motherboard and ram. good idea yes or no ?

why prefer i5's - GET HYPERTHREADING WITH THE i7 8xx (1156) and 9xx (1366)

if the OP has the $$$ then get it, plus you can fit 50% more ram into any rig with the 1366 socket thanks to the extra memory channel

I'm looking to making a newbuild still and have been debating a lot of the things on this thread. In regards to futureproofing I think it's always a gamble because it really depends on if and when you are going to upgrade. If you go 1366 now, you spend a little more but you shouldn't have to worry about amount of RAM compared to 1156. Also if you do decide to upgrade processors later, I would imagine if you are looking at a year or two, hopefully there will be cheaper 6cores and not the $1K's only.

That being said, you could always argue to save the money you save now going 1156 compared to 1366 and either use it for other components, or just save it and in a year or two, you should have plenty more for possibly a more comprehensive overhall of say MOBO and CPU.

While I'd have to agree USB3 and SATA 6GB should be gotten on new purchases, implementation of it still seems to have a long way to go as right now it doesn't seem to be ideal with 1156, and even 1366 I've read is suboptimal.

I think futureproofing is the hardest one, cause I think it'll depend more on what you want to upgrade later. I mean getting a bluray burner may be more futureproof than DVD burner right now, but if you look to upgrade later, I'm sure you'd have spent less on the dvd burner now and a future bluray burner that is better than the one you get now.... oh the decisions...

No. No current generation CPU will limit the GPU. It just doesn't happen.
