I'm custom building a computer for a friend and I want to make it as easy to upgrade as possible. I have been looking at amd cpu's mostly because of cost but some of the motherboards say am3 socket and list specific cpu's they support. does this mean that only some cpus can be used on these boards even though the socket is the same?

CPU = Intel i7 950
Motherboard = Asus P6X58D
RAM = Corsair XMS3 DDR3 6X 2GB
Power Supply = Corsair AX1200W
Graphics Card = GTX 580 2-way SLI

Yes only the specific processors the motherboard list will support it although they are the same socket.

<<...I want to make it as easy to upgrade as possible.>>

In that case. simply get a motherboard which supports the latest socket type, although that's no guarantee that future sockets will work on said board.

You can check either of the websites for the CPU makers...to find out what they are willing to reveal about future and present producrs.

The speed of product change...is much faster now than it was formerly perceived, IMO.

The important thing, IMO, to realize/accept...is that backwards compatibility is one thing...while tying oneself to the same socket over any prolonged period of time...does not maximize the profit potential for either CPU manufacturer :). Ditto for motherboards. The motherboard manufacturers and the CPU manufacturers...are partners in industry.

Not all AM3 boards support all AM3 CPUs. It is mainly due to wattage limitations on cheaper boards. If you have a $50 AM3 board with a 3+1 VRM setup, running a 135 watt 6 core CPU might be a problem. As an example, the Asus P6X58D has a 16+2 setup, which is happy for a 135 watt Socket 1366 CPU. A bit of a difference between a high end Intel board, and a cheapie AMD board. (Not that AMD boards are in any way inferior, it is mainly a low cost/high cost division no matter if its AMD/Intel)

Pay attention to the power section on AMD boards. That has been the main failing as far as I can tell. It seems since AMD is the budget option, board OEMs seem to make cheaper products since they perceive shoppers are looking for inexpensive products vs Intel buyers.

EDIT: Not that power phases are end all for wattage determination. It is possible to design a 3 phase that will do 125/135 watts. But when you see a 3 phase, with no heatsinks, it is kind of a warning to avoid high wattage CPUs.

If you are building this PC for future upgrade possibilities, you should look at an AMD 900-series chipset motherboard. These will support AM3 CPU's and upcoming AM3+ CPU's out-of-the-box. Get a standard ATX motherboard, not a micro ATX, due to thermal issues with smaller boards. Also, AMD 970 series chipsets are basic and fine for most PC's. 990FX motherboards are meant for people running multiple graphics cards and the gamer market, thus, they are more robust.

Gigabyte and Asus makes some nice 900 series chipset motherboard.

A Cheap motherboard will be a cheap motherboard in all aspects. Longevity of parts on a cheap mobo will be lower. It may not have as many memory slots or drive ports or places for add in cards etc. It may not be as stable.

Buy the CPU and Motherboard & Memory from someone that will guarantee they'll work together.

I'll agree that there are some low quality boards for AMD since the perceived buyer is bargain hunting. They also tend to not last as long as a good board would.

I like ASUS myself. Look on Newegg or amazon and read the reviews before buying. Get USB3 it is coming on strong.

you can skimp on some parts of a computer, but the two components I always recomend not skimping on is the power supply, and the motherboard. Spend a little extra on those and make sure you get good quality and that they do what you need them to do with room to upgrade-these are the two hardest, and most expensive parts to replace on any computer, and using cheap PSUs or motherboards can lead to major problems in the future. Its better to go with a lower grade memory or smaller hard drive, or even a slower CPU if need be. And check the compatibility list-sometimes a CPU not on the list will work, but I would never count on it.

The compatibility list can be weird sometimes, my cousin bought a Pentium D and according to the Intel motherboard compatibility list it would work but it never did which just weird when he has already updated the BIOS.

With Pentium D on older motherboards especially you need to look at the number too.

Pentium D 650 might work and a Pentium D 820 could not work. Single core vs Dual core.

The one he bought could be a newer stepping that wasn't supported. The SL number also matters.
Example Pentium D 650 SL8Q5, that one didn't work on a motherboard that supported Pentium D650, just not that SL number.

All pentium Ds are by nature dual core, but the advice is correct, you cant just throw a pentium D into a motherboard that says pentium D, you have to match the numbers up. What normally throws them off is the different FSB, with socket 775 the FSB of the CPU has to match the FSB of the motherboard, or they just plain wont work. There are other factors as well, which is why its important to follow the CPU support list, especially with intel.

You might as well get a high end board that can support most Intel/AMD processors. The 2nd Gen i series are pretty easy to identify and there arern't many different versions, so there would be minimum mix ups.

Oops, my bad, where I said Pentium D 650 I meant Pentium 4 650, that's what happens when you get in a rush.

I thought you had made mistake because i actually have a Pentium 4 650 lying around in my spar parts bag.
