I've noticed there are some micro ATX boards that are about $20 cheaper and have built in graphics and only 2 slots for RAM. I think I might be willing to live with only 2 slots of RAM, but I'm not sure if the built in graphics will be an issue.
Will having integrated graphics that are disabled have a negative effect performance when compared to a motherboard that has no integrated graphics at all?
Hmm since you picked out an AMD mobo here are some things i think you'd be interested to know
2 DIMM /IGP/mATX (AM2+) chipsets
Most of these aren't designed to take in more than a 95W TDP quad chip so for an upgrade path you be looking at the incoming AM3 95w TDP Deneb/Heka chips and these aren't exactly designed to hit high clocks though unlocked multi chips may be an exception
If you are looking for 4 DIMM/IGP/mATX (AM2+)
790GX (DFI and Biostar only so far)
Some of these can take it the baddest quads out there and i have built a Biostar TA790GX XE mATX with a Phenom 2 x4 940BE for a rendering/modelling shoebox crazy dude and my god it flies! The 790GX come with SB750 and have ACC
Lastly to answer your question:
The results of peeps on 790FX/790GX OC on Phenom 2 suggest there is 0% disadvantage by having an IGP however purists wouldn't have anything less than 16x + 16x multi GPU in their mobos so this would favout the 780a and 790fx AMD chipsets. Hope i helped
Very interresting. Now the board I picked out has a chipset you dont mention, the 770. Will this chipset be sufficient for the Phenom x4 9950 2.6ghz?
I'm also looking into a motherboard with an nForce 720A, as I've had more expirience with nForce boards than with AMD ones. And it has been a good expirience.
I wanted to get a Phenom II, but it's just out of my price range.
It's worth noting that I've been building machines since I wasa kid. I've been out of the loop for the past 2 years since I got married. Not enough money to keep upgrading every 6 months. So I'm a bit rusty.
