Hi I my friend and I are building a computer from scratch, and we are looking for help forming the base of our build. We have a core i5-750 processor, socket LGA 1156, and we are looking for p55 motherboards compatible with it. We plan on using 4GB Gskill ripjaw (2x2gb) ddr3 1600 Mhz. We would also like 2 pci-e inputs that can operate at at least x8 and x8 when in crossfire/sli. Atx or matx does not matter for us. Our price range for the motherboard is around $180 max. We are in US, and were looking on Newegg, but cant seem to make a decision. We were thinking about the Gigabyte UD4, but on newegg it says it doesnt support 1600 mhz ram. The MSI p55-gd65 is another option we were considering. If anyone can recommend a motherboard/motherboard brand, we would be very grateful.

Thanks!

The UD4 is a fine motherboard, and while it doesn't say DDR3 1600 (???), i'm sure it does support it.

Found this on gigabytes website. Shows DDR3 1600 support for the ud4. Im curious as to why newegg doesn't have it listed on their site. Does the ud4 support x8x8 Crossfire? Also just found the previously mention MSI board is cheaper than the ud4. Any suggestions?

Well many boards are cheaper than the UD4 at $140, that doesn't mean its a bad board.
At the same time, the MSI board I think you're talking about is great too. Just depends on how much you want to spend. I personally don't think there is too much a point spending lots of money on a board as long as it is reliable and does what you want it to.

I think that there's some confusion with supported memory speeds due to the H55 / H57 chipset boards. Memory support is limited to 1333Mhz while using the integrated graphics CPUs. With an add in video card the speed goes up.

Newegg sold integrated graphics boards (Gigabyte H-55) with i5-750 CPUs, and got most of them back due to the fact the 750 DOESN'T have integrated graphics and wouldn't boot without a graphics card installed. Needless to say, customers expecting pretty pictures out of this combo were deeply disappointed. Point being, I wouldn't take Newegg's blurb as the last word for memory support speed with any of these boards at the present time.

I'd personally look at a board with USB3/SATA6Gb functionality if your friend is planning to keep the core of his system for any great length of time. In order of my personal preference:
ASRock P55 Deluxe3 ($173 inc shipping)
Gigabyte P55A-UD4P ($178 inc shipping and rebate)
Asus P7P55D-E Pro ($190 inc shipping)
Most P55 chipset boards will offer similar performance, so increased cost comes down to feature set- some valid (better audio codec, PCIe based Gb LAN rather than PCI etc) and some debateable (number of power phases), and some fairly useless (OTT heatsinks).
I wouldn't rule out a board that had x16, x4 bandwidth PCIe x16 slots. Unless your friend is planning on Crossfiring/SLI dual enthusiast grade cards then the performance drop between x8 and x4 is modest at best.

I though USB3 or UD3 or something supported USB3 and SATA3 at $120 or so, I can't find it though; probably a dream .

No dream...
GIGABYTE GA-P55-USB3 ($116 inc shipping) - nice board too. Tho no SATA 6Gb.

and disregard that first review about the x4 PCIE slot. the performance drop between 16x and 8x is nominal and around 8% for a x4 slot, even for the monster cards. an x4 slot is very useful for crossfire unless you only care about squeezing every last frame for benchmarking.

First, I wanna just confirm what red1776 said, and the difference between x4 and x16 isn't really much, and any difference is really noticeable only on benchmarking.

That said, SATA 6GB is really only needed if you're thinking of going the way of SSD. I doubt HDDs will need much more than the SATA 3GB available now.USB3 however is something that will be more widely used given the widespread use of portable HDDs. However, flash mem speeds for USB/camera/mp3 players haven't really climbed as much as flash mem on SSDs, and is still a bottleneck as far as I'm concerned.

Also, is overclocking part of your plan? Probably going to be a minor point, as most boards today will support it to some extent, but it'd just be nice to know.

mmm...thats true, but ssds are a pretty easy, very viable, and very attractive upgrade later on.

I think this motherboard is good ASUS P7P55D Deluxe LGA 1156 Intel P55 ATX Intel Motherboard

Nice board...unfortunately the thread title reads "Choosing a P55 motherboard on a budget"

Its 184$ at newegg.

My apologies b44g6, it is indeed (actually $165 after rebate if you believe in such things). I initially was looking at the USB3/SATA6Gb (P7P55D-E) version of the Deluxe ($250).

We were actually planning to get a small SSD as a boot drive and to store a few programs on. We were looking at something around 64gb. Does SATA 6Gb speed reallly make a difference or is it negligible? We don't mind getting a USB 3 motherboard as long as it fits our budget. As for crossfiring, we are looking at 2 Radeon HD 5770's. Does thing change anything in terms of what we would need? DBZ said that unless we were planning on enthusiast grade cards, we wouldn't need x8 x8 lanes, do the 5770's classify as "enthusiast grade"? Also the GIGABYTE GA-P55-USB3 that DBZ mentioned doesn't have x8 x8 from what I can tell. Would this bottleneck the 5770's? Thanks for all the suggestions.

A SATA mechanical HDD has no chance of saturating a SATA 2 buss (@300Gbs) let alone 6 Gbs. SSDs flirt with the 300Gbs spec, but in read only.

The only commonly available method of perhaps exceeding the 300Gbs would be a couple of SSDs in RAID 0 while reading.

I would definitely choose
Gigabyte
or
Asus, no MSI.
the types are mentioned above, and you will choose looking at the price. Remeber to have SATA 6Gb and USB 3.0, then you will be satisfied with your i5

Firstly, most ssds don't even have sata 6gb/s interface, so current generation drives won't be particularly effected. Correct me if i'm wrong, it was more a guess.

Well, that's the irony of the advertising business, you simply must have SATA 6Gbs, you're never really informed why it's a must. As ironies go, you can now buy a WD "Caviar Black" 1TB 6Gbs HDD. It's no faster than the old 3Gbs that it replaces, just more money.
