im about to build a new computer that will mainly be for online FPS and home theater, using Vista64 Home Premium , Samsung 226bw 22in HD LCD, Logitech Z-5500 5.1 Speakers,
i will list the hardwares that i already have in mind
E8400 OCed 4ghz at least
GF9900 (newer technology) when they eventually comes out
PSU: OCZ GameXStream 700w
Seagate Barracuda 7200.11 500gb 32mb cache NCQ
Fan: Cooler Master Neon Blue LED 120MM Case Fan 3PIN 22DBA 1220RPM 42.734CFM 3PINS

for RAM, see lower
=========================================================




my main question is, WHAT MOTHERBOARD?!??!
P35
i might not want to pay too much for a mobo as i'll prolly change it a few monthes after Nehalem is out... so in that case, p35 would be the best for me right? or maybe i ll just make another build from scratch for Nehalem with DDR3, etc?
BUT... will the gf9900 be bottlenecked by the p35??, can I OC the E8400 AND use 4x2gb DDR2 1066mhz in dual channel too?

780i
im not too sure if i want SLI or not... i was thinking that i could buy a GF9900 when its out, and then maybe 1or2 years later, i could add another same card to SLI... not sure if this is a good idea tho? what do you think?
i know i can OC E8400 to 4ghz and i think i shouldnt have any problem with 4x2gb DDR2 1066mhz on 780i, right?

X38
best OCer of all 3 i beleive... i can prolly reach more than 4ghz with my E8400, and should have no problem with 4x2gb DDR2 106mhz in dual channel
i might need to get this one if the p35 bottlenecks my gf9900, or if i dont want SLI or even if i end up with ATI cards cuz gf9900 sucks, then id also have the possibility to Xfire 2ATI GPU!




RAM 4x2gb
im not too sure if i will use DDR2 1000mhz or 1066mhz, but I know im am not willing to OC the RAM because I dont care paying 20$ more and not having to OC:p 

for 1000mhz i was looking at those 2
115$
G.SKILL F2-8000CL5D-4GBPI Pi PC2-8000 4GB 2X2GB DDR2-1000 CL5-5-5-15

http://www.ncix.com/products/index.php?sku=29797&vpn=F2-8000CL5D-4GBPI&manufacture=G.SKILL

http://www.ncix.com/products/index.php?sku=28032&vpn=OCZ2P10004GK&manufacture=OCZ%20Technology

I think CL5-5-5-15 is better than 18 right?



for 1066mhz i was looking at those 2
130$
OCZ XTC Platinum Edition PC2-8500 DDR2 4GB 2X2GB DDR2-1066 CL5-5-5-18 EPP

=====================================================
So what do you think?? What would u do? And why??

If you guys may recommend specific models for each motherboard, that would also be greatly appreciated!!

If you have any other tips/advice or anything that I should be aware of or that might make me reconsider, let me know!

Tx a lot for your opinions/expertise in advancE!!

May 2, 2008 4:28:04 AM

I would go with X38, a good P35 board should hit 4GHz.
Do you need SLI?
May 2, 2008 4:39:38 AM

To go sli in a year or two your GPU will be out dated.
Related resources
May 2, 2008 10:41:35 PM

yeah i think im prolly better off without SLI
so x38? or p35? what are the differences?
May 2, 2008 10:46:31 PM

P35 and 780i run at 1333mhz fsb natively, and oc reliably to 1600mhz. X38 run at 1600mhz natively, and oc reliably to 2000mhz. 1600mhz = 3.6ghz for e8400.
May 2, 2008 11:38:14 PM

^The market is seriously missing "X38 FTW" marked boards.
P35 is becoming the low budget OC chipset fast. P35 will be replaced by P45 in about a month. It basicly has the same features as X38 and will likely share it's price also.

By that time HD 4870 should be out also making it clear if you want CrossFire support or not

Does p45 support crossfire? And what process? (90nm? 65nm?)
May 3, 2008 12:12:38 AM

if p35 supports 45nm, im pretty sure p45 will too..

lets say im taking x38, oc its fsb to 2ghz (500mhz for Ram..) that means i can use some 1066mhz RAM in dual channel with no problem?
wut happens if im using 4x2gb 1066mhz?
will i have to kindo downclock it?
May 3, 2008 1:11:21 AM

P45 supports CrossFire (16x/16x v2.0 slots) from the previews (some Foxconn board - http://www.techpowerup.com/59259/Foxconn_Intel_P45_Quan... ).
I hope that's a custom feature cause X38 will go the way of the dinosaur if that's a stock feature.

I guess it'll be made on a 65nm process.
Supports the whole Core2 (45nm + 65nm) range and DDR2 and DDR3 memory.
May 3, 2008 2:09:36 AM

So which way to go with the mobo is the hardest part.

I too have everything else picked out,

E8400
8800GTS G92
PCPC 750
Armour Case

I just can't decide between 780i and X38.
I will be gaming on a 24" monitor that supports 1920x1200,
BUT one 8800GTS will support that resolution, so I probably
don't "need" SLi. Yet I still don't know which one would be
better?

780i has sli and x38 has crossfire. sli is equal to crossfire, not greater.

Nvidia and ATI historically take turns as industry leader. The recent hype with sli will one day pass, when ATI digs itself out of the hole. If this early benchmark for 4870 is real, then that may happen at the end of May, when 4870 is released.

I won't be a guinea pig for a new mobo, so which way would be the best at the moment between the X38 and 780i?
I game, have a large monitor, but I also want something that's stable. I know I've read about problems with some 780i boards. Even though they've had problems I'm still leaning that way. What's the benefit with an X38 board over the 780i?

is it possible to use DDR2 1066mhz in dual channel with an OCed x38 and E8400 ??? thats pretty much my last question im wondering before making my order!!

Over say a ASUS P5E LGA 775 Intel X38?
http://www.newegg.com/Product/Product.aspx?Item=N82E168...

$70 difference is prety huge for a mobo IMO.
Bragging rights [worthless]. A nicer box. More accessories. A nicer name and a nicer looking board, X48 over X38 chipset, some leds, potentialy higher overclocks but not by much. That about covers it I think. Maybe S.T.A.L.K.E.R. Shadow of "I can't spell that in english" ? Not worth it if you're on a budget or don't care about those features. Worth it if you're a ROG fanboi or hate gigabyte's "box of crayons" coloring scheme.

DDR2 DC 1066MHz is possible anyway DDR2 DC 800MHz is possible. Only the ratio is different and it keeps you covered upto 533MHz FSB.
May 3, 2008 2:59:46 PM

Yeah, the x48 is almost identical to x38 in term of overclocking performance. It is slightly better, but not worth the price if you're on a budget. And ram timings don't matter. It makes little performance difference anyway.
May 3, 2008 6:24:01 PM

^What really bothers me is the fact that P45 has just about equal specs to the X38 and that has the same specs as X48. So 3 chips same features same price ... not really a clear image of performance grades. WTH?

I thought the p45 use 65nm process instead of 90nm (the chipset itself, not cpu support, btw :p  ). Are there any p45 benchmarks out yet?
May 3, 2008 7:22:59 PM

^I think I said it was on a 65nm process yes.
No benchmarks I know of yet. The board previews are more feature related. It's an Intel. It'll kick ass and chew bubbulegum.
May 3, 2008 8:26:02 PM

Im glad you posted this thread as i am in the exact same situation as you..in fact this is driving me mad!

Particulary what bothers me is the amount (or lack of) Motherboard manufactures actually testing 4x 2GB Dimms in configuration.Every site, every motherboard QVL list shows no 4x2gb modules and IF there is a 2gb module singly listed, it will only be tested to work with two installed, not 4.

As the ram i am using currently Adata 2x2GB CL5, is causing problems in my SB600 based Abit F190HD i am very concious about this!

I just want to know a board that has the best compatibility with 8GB ram!
May 3, 2008 8:53:39 PM

Why do I have the feeling that SB600 is a SouthBridge and is likely not the cause of these issues.
A-Data 800MHz CL5 is the cheapest RAM local shops have in stock.
I've had no issues with (Corsair, Geil, Mushkin, Kingston) 8GB configurations in the past 3 months (since people started buying 8GB).
3x P35, 5x X38, 1x X48 systems. MemTest86 takes ages to complete ...
May 3, 2008 8:57:45 PM

wut are the major differences between p35 and x38????!!!!! only Xfire?
i will be buying some GF9900wutever when its out (newer technology than G92).. do you think i could have problems with p35 since they re a bit old?
im kindo leaning toward maximus formula x38 right now..
X38 OR P35 AAAARGHHH i need help i gotta ORDER NOW!! mega sale eh ;) 
May 3, 2008 9:12:12 PM

Well i tested with my board, one of the 2GB dimms doesnt let the board post, the other does fine. However previouisly somehow i managed to get all the dimms to boot and i ran memtest, no errors.

It seems its something with the ram modules and this board, probably because they are the cheapest, like you said:p 

Anyway, my plan is to buy a new ram kit and new board, almost certainly not from Abit or Adata!
May 3, 2008 9:17:21 PM

Personally i am swaying towards a p35 board, now im stuck choosing which one. Id love to get the DFI Blood Iron, but in the Netherlands its very hard to find and when it is found, you have to wait a couple of weeks or months probably (in my case/luck)

Which leads me to several more choices. I go with a 150 EUR Asus P5E based on the x38 chipset.

OR

A cheap reliable P35 board (as the higher end boards either dont justify the cost, or have a useless extra GBLAN port or x4 PCIe secondry slot.


Also, an affordable X48 board is the Msi X48c, this retails for 180 and supports both DDR 2 and DDR 3 along with crossfire, pcie 2 etc. However i very much doubt that DDR 3 will be an advantage in the future as benchmarks currently dont show any difference. So whats the point of getting a combo board for a tech that doesnt show any advantages to DDR 2 on the same board?
May 3, 2008 9:23:53 PM

@ FwoGiZ

If you plan to get such a beast of a card in the future, its probably best going for one of the nvidia boards. Reason being:

1- At the moment there is a very slight difference in performance between pcie 1 and 2, the more the resolution and quality etc, the more the difference.
A p35 board only has PCIe 1 so this may,although it will be compatible, push that video card back a bit compared to a pcie 2 slot.

2- An nvidia 7xx series board supports sli and pcie 2 meaning you will have the option to add a nvidia card in the future (you wont have this with the intel chipsets as they just support crossfire)

3- Your video card and mb will be made by the same chipset. This shouldnt cause a problem running an nvidia card on an intel board that supports crossifre, however somehow it seems a waste.

4- Nvidia board and nvidia gpu looks best on paper.
May 3, 2008 9:41:51 PM

yeah p35 might indeed bottleneck my gf9900...
i dont think there are any differences between pcie2 of the x38maximus formula and the one on the 780i... am i right??
i dunno bout using SLI.. i might even change that board and maybe whole gear when nehalem comes out.. so i dunno
gosh, such an hard choice
May 3, 2008 9:44:06 PM

If you're looking at the X38 chipset I say go with GA-EX38-DS4 or ASUS P5E.
$207/$225 is not a big difference for a board and both have great features.
I like the layout of the ASUS better but it also has drawbacks.
The Maximus Formula/Rampage Formula offer no real value over these boards but cost $50/$75 more. DDR2/DDR3 combo boards are useless.
DDR3 will be a bleeding edge product for at least 2 more years.

As for MSI boards I don't have any experience with them.
May 3, 2008 10:14:35 PM

Andrius, from your experience, which is a good priced reliable 8gb ram kit for those boards?
May 3, 2008 10:16:47 PM

There arent any differences between the pcie 2 on either board. If your not bothered bout SLI, then you can run that card in a crossfire certified mb no problem i think. However i just thought maybe youd like to go nvidia/nvidia.

You may even want to get a pair of 4500 ATI cards when they come out ;) 
May 3, 2008 10:22:18 PM

Not sure why so many people are having problems with 4 sticks of ram. I ran 8gb of ddr2 800, and it overclocks to 1066 too, completely stable. :p 
May 3, 2008 10:35:34 PM

dagger, whats the make and model number of your ram?

Corsair DHX C4 and C5 worked perfectly for now (2 of each). Dominator on X48 was a cakewalk.
Geil Black Dragon 4x2GB work good on X38 but ASUS P5K Pro/Premium had issues with C4 for some reason.
Voltage didn't help (2 of these kits GB24GB6400C4DC). They have RED LEDs. UGLEE!
Kingston Value RAM was C5 and worked like a charm on GA-P35-DS4.
Mushkin Extreme kits worked on a GA-X38-DQ6 but it took some tinkering to get them Prime95 stable.

I changed the content of my thread and the title, so dont be too confused! I just dont wanna spam :X
Tx^^ bumpage
May 4, 2008 4:51:45 AM

I think after this thread I'm heavily leaning towards the X38 based board.
It overclocks well, I'm not starting out with SLi, even though I thought it would be cool. In reality one graphics card is all I "need" and later if there's a better card, I'll buy it and or a new mother board once the X38 is obsolete. It's a stable proven mobo and now it's just down to which manufacturer has the best X38.
May 4, 2008 10:56:01 AM

FAST LS1, im a bit confused with your choice, if you dont want SLI or Crossfire, why get an x38 board?

Youd be better off spending 75 Euro instead of 150 Min on a p35 board with just 1x PCIE Slot.

The only reason one would favour the x38 is for two full PCIE lanes for crossfire.

P35 and 780i run at 1333mhz fsb natively, and overclocks reliably to 1600mhz. x38/48 run at 1600mhz fsb natively, and overclocks reliably to 2000mhz. 1600mhz = 3.0ghz for Q9300(7.5x), 3.6ghz for Q6600(9x), and 4.0ghz for Q6700(10x). If you use a cpu with low multiplier, such as q9300, the high fsb is needed for overclocking.
May 4, 2008 3:09:21 PM

yup and does anyone know if the p35 wont bottleneck the high end new technology gpu card that will come out at the end of the summer? GF9900 has new technology and i hope its gonna kickass,
i think i might get some gigabyte ex38 ds4 MB so that it doesnt bottleneck my gf990 for sure, AND if by any badluck the gf9900 sucks, i can always XFIRE 2 new ATI cards that seems pretty good too ;)

X38/48 use 2x PCIE2.0x16, think of it as PCIEx32. P35 use the old PCIE standard. But graphics cards at the moment aren't nearly powerful enough for the old PCIE to become a bottleneck. So no, p35 won't bottleneck your gpu.

True. But it might in 2-3 years. So that will give him another reason to pick X38. ;) 
May 6, 2008 12:35:06 AM

Exactly, even though I could get by currently with a P35 I want some future proofing. I'm seriously looking at the X38 boards for that reason. I'm not crossfiring right now because I'll be buying an 8800GTS VGA, but a year or two from now they might have some decent crossfire graphics cards. The X38 cards have other layout advantages too over the P35's from what I've read, even though they are not really important differences.

4870, to be released at the end of this month, ought to be decent enough for that crossfire.
