The title says it all. I've been going nuts trying to guess how to intelligently buy an AMD motherboard so that I'm ready for the future. The past has alwayas been to purchase AM3+, but now it seems AM3+ has basically no support for PCIe 3.0 GPU's. And while I have researched 3.0 GPU's enough to know that people tend to say the extra bandwidth is mostly a 'marketing gimmick', its still the fact that the newest GPU's are only being made for the PCIe 3.0 interface.

I've currently got an AM3+ MOBO and want to update my graphics card (and am also planning three new computer builds,) but it seems like FM2+ is the only AMD MOBO that really supports it. Should I buy an FM2+ MOBO? Does AMD plan to support 3.0 with AM3+ MOBO's within the next year? Is it safer to stick with AM3+?

Most importantly, I've read a lot of GUESSES around the web about what AMD plans to do in the future, but I'd like to know directly from AMD or the people who really know: where does AMD plan to go from here?

Also, what's the difference between FM2+ and AM3+ anyways?

PCIe 3.0 is backwards compatible to 2.0, and unless you are running 3 or 4 top end cards, such as the 290X, you're not going to exceed the PCIe 2.0 x16 bandwidth. PCIe 3.0 will help in reducing costs because the speed of PCIe 3.0 x8 = PCIe 2.x x16.

Socket FMx is the socket for AMDs APUs, whereas AMx is the socket for CPUs. They use two sockets because the "chipset" is integrated into the APU whereas it is separate on the board for a CPU.

If you do any real non MMO gaming (as in Crysis 3, Battlefield, CoD, etc...) then you need to go with an AM3+ setup. If you just browse the internet, watch movies, and play MMOs OR play games at a lower resolution (1280x720) then you should go with an FM2 setup.

you got to also think that with AM3+ your buying into the past and not much forseeable future.  in my opinon what do you get ?? an old phemon2 board thats been reworked for the AM3+ chip ,  do to the next gen chipset[1090rfx] been droped no pci-e3.0 realy no nothing. now if you could hold off till the next gen of FM2+ chips come out it may be worth the wait.  AMD may have a top end chip and then you get the latest newest board with the pci-e support you want and no telling what else. as far as i'm conserned am3+ is one foot in the grave and the outher on bannana peel.  i been through 3 AM3+ builds 2 sabertooths and a giga 990fx ud3 and its been just a letdown.  but hay its up to you good luck.... hold on i think i hear some blueguys knockin at my door.

I built a new box last spring and I continue to use an older Phenom II CPU which runs well on the 990FX chipset based board.

I have Metro Last Light that evidently runs at 20fps on a console, my box plays it at 60fps easy.

I play at 1920x1080, the console was 1280x720 and still 20fps.

Most recent was the GTX 660 TI which is insanely more powerful than the Xbox 360 or PS3 and its even more powerful than the xBox One or PS4

I can bolt on another GTX 660 Ti or another card should games become too sluggish.

I recommend a 2-way or even 3-way board, just to have options

I realize that such setup needs an extreme PSU as well

Yep, DDR4 is around the corner too and it will require a new mobo - I would wait for it!

At this point while FM2+ is guranteed an upgrade to the Kaveri core, AM3 doesn't have a real release schedule of any Steamroller based next gen CPU as of yet. Mainly because the AM3s are based out of Global Foundries and their shrink processes are stuck at 32nm.

I'd wait till they release the A10s based on the Kaveri core next month and buy a fully compatible mobo then.

DDR4 is indeed around the corner but consumer grade release would probably be no earlier than next summer and prices should start coming down end of 2014, however I could almost predict that the price per GB won't come down to the present DDR3 level for a while.

Unfortunately, there is no good choice.  With development moving at its current pace, and the drive for profit, manufacturers are dropping support for graphics left and right.  I discovered this after upgrading my MOBO to a Gigabyte with RADEON 3000 chips onboard.  I run Linux and support is GONE.

Better to plan for buying a video card and a big power supply.  And upgrading later!!

You can blame republicans for the econonomic mess as well as greedy bankers

DDR4 is over 2 years behind expections

I use Corsair PSUs, seem to be rugged in my shop
