Need advice on new mobo

post #1 of 20
Thread Starter 
Hey everyone,

I'm looking to buy a new motherboard. I have an i5 2500k that i'm looking to overclock. I also have 2 HD 6850's so it needs crossfire support.

What I'm having trouble with is I'm not sure how performance is divided up between PCI-E slots. My mobo right now has a x16 slot and a x4 slot which my 6850's are in right now.

This is the motherboard I've chosen - http://www.newegg.com/Product/Product.aspx?Item=N82E16813157265 and the PCI-E slots are configured as dual x8 slots. Will this give me better graphics performance than the x16 and x4 slots on my current mobo?

I'm pretty set on this motherboard I'm just looking for a second opinion. If you guys can find a better one for around the same price I'd love it if you could link it.

I also need new RAM. I'd like to go for a 16gb kit @ 2133mhz. Is it futureproofing or overkill?

Thanks in advance smile.gif

Your current motherboard will be running 4x 4x for crossfire. So, with your new one you will get 8x 8x. There should be a gain, as you are receiving more bandwidth however the notice won't be huge.
As for RAM, i would say that 2133Mhz is a little overkill, 1600 would be fine to be honest. thumb.gif

EDIT: Much better for your needs. As OC boards P67 Extreme4 is probably slightly better.
With those two you get Z77 chipset and it's perks.

So the Z77 chipset is able to overclock? I made the mistake of buying an H67 chipset last christmas. And I want to get the most out of my dual 6850's

Yea, H is the only one that doesn't. P67, Z68, Z77 are all able to OC. Z77 is the latest and offers native Intel USB 3.0 ports, and PCI-E 3.0 on all boards (with Ivy Bridge though). Z68 and Z77 offer iGPU support over P67 and SSD caching.

Get a z77 board, then, if you feel the need to upgrade to take advantage of PCI-E 3.0 and the other benefits ( Lucid virtue for example ) you can buy an Ivy Chip.

or just grab the z77 version of the extreme4

http://www.newegg.com/Product/Product.aspx?Item=N82E16813157293

its on sale for only $105 + free shipping !!!

pair it up with a CM 212 cooler and you will easily hit 4.2-4.5ghz with the i5-2500k. if you want to hit more, then you need higher end boards + a good power supply. but the extra increase in mhz is so negligible.

1600 mhz of ram is all you need. and anything under $40 and 1.5v.

http://www.newegg.com/Product/Product.aspx?Item=N82E16820220685

i recommend this. $30 after rebate and free shipping

I'm a fan of ASUS mobos and was looking at the P8Z77-V LK. It also has an integrated wifi card and that would help a lot at LAN parties. What do you think of that one?
