How much the motherboard with same processor increase performance?

[guilherme]

Hi all,

I´m thinking to buy a core i7 920 proc but i have this two motherboard options:


Asus P6T SE 1366 - 448 USD
Asus P7P55D LE - 320 USD

As you can see, the price difference is too big - in my point of view - but i wanna know if the performance will be MUCH better on the P6T that justifies it´s price



Thanks!!


my english is not so good, sorry

It depends on what you're comparing it to. What's the other motherboard? CPU?

if your thinking of buying an i7 920 the second motherboard you listed would not be compatible as it,s a socket 1156 and the i7 920 needs a socket 1366

 

[aford10]

expat is correct. The 2nd motherboard you listed, is for the new i5/i7 1156 socket. The i7 920 uses only the 1366 socket.

Where are you ordering from? Those prices you listed don't look like USD prices.

 

[guilherme]

you´re right!

P7P55D can use the i7 870, but not the 920 i checked the asus site carefully... thanks, this change everything. I will go to the P6T i think...

And this configuration, which one is better?

- P7P55D with intel i7 870 or P6T with the i920? because the clock of the 870 is higher than the 920...


-> It´s Brazilian prices, we have high taxes...

There's a lot of debate on which i7 is better, the 920 or 860. The 920 can OC just as high as the 860, so I don't think the frequency matters that much.

To me, one of the big differences, is the dual or triple channel memory. If you consistently use ~ 3GB of RAM, but not more than 4GB, you don't want to be strapped by 3x1GB, but you won't use 6GB (3x2GB). In theory, it's wasted money. If you use a lot of intensive apps, such as video editing, you may want more than 4GB. Which, in that case, you want the triple channel 3x2GB.

They are both very good CPUs. If memory usage isn't a problem, and if you can find a good deal or combo with one, that's the one I'd choose.

have you considered the i5 750 for the p7p55d has it performs on par with the i7 920 cosumes much less power and the complete platform costs about a 100 dollars less it all depends on what your going to use your pc for

 

[aford10]

The i5 is a good CPU for lighter workloads. It's quick and runs well on single video card setups. However, it lacks hyperthreading support that the i7 920 has. In heavier workloads, and dual video card setups, the 920 will smack around the i5.

i will do an upgrade in my computer because i want a better performance os Flight Simulator X, as it uses more CPU power than the video card - i have an 9800gtx+ - the i7 will be better.



thank you

The i7 920 really is a beast. You pair it up with a good OC'ing motherboard, and you can easily get it up to 3.5Ghz on air cooling.

I will buy this components:

- Asus P6T
- Core i7 920
- Cooler Zalman CNPS9900A
- 3x2Gb Patriot Viper DDR3

The memory speeds (1600 or 2000mhz) will make much diference on the performance? I read that 2000mhz is better for overclocking...


thank you

 

[aford10]

The P6T will support memory OC'd to 2000mhz. There's no guarantee that you'll be able to buy DDR3 2000, and OC it any higher. For most applications, the performance difference will be negligible.

so, i choose to buy the p6t se/i7 920/patriot viper 1600mhz 6gb - and i already installed into the case and connected all the cables. The only components that i´m using from the old machine is the 550w "power font" (?), 2 SATA hds, 1 DVD and the case. I didn´t format the Hd´s just to compare the performance after upgrading, but the OS (Vista) don´t completely load, it stops on the animation logo at the startup sequence.

What should be causing this error? I tried to boot in safe mode and didn´t work too....I don´t wanna format the entire hd and install the windows 7 before comparing with my old specs (including OS)


Thanks

You'll need to do a windows repair, because of the hardware change. Tap f8 on startup to access the safe mode menu. There you can access the repair options.

didn't work. I booted in safe mode and the windows stops on "crcdisk.sys"...looks like a driver problem.

 

[aford10]

My fault. I was thinking of Windows 7 repair (which is located in the safe mode menu).

If you want to repair your old OS installs, you'll want to boot off those discs. Agree to the license, and at the next screen, use the R option to repair your install. Here's a guide with screenshots.
