AM2+ with DDR2 vs AM3 with DDR3

post #1 of 4
Thread Starter 
I'm in a pickle. I currently have a Phenom II X4 940 AM2+ system that I use for audio purposes, but I want to put together a gaming rig as well (I need to keep these two rigs separate).

One possibility I have come up with is to just buy a cheap AM2+ dual core to put in the audio rig and take the 940 for my gaming rig. That would make the cost of my gaming rig only the cost of a mobo + the cost of the cheap processor to put in the audio rig, since I could take some of the RAM from the audio rig as well. This would cost me about $80 total.

The other possibility is making a full AM3 build with an AM3 Mobo, AM3 CPU, and DDR3 RAM. Without making a build up at Newegg, I imagine it would be in the neighborhood of $250 ($70 mobo, $60 RAM, $120 CPU).

This is a huge cost difference. Are there benefits to AM3 and DDR3 that I am not seeing? I'm ready to pull the trigger on the cheap build I listed above, so if that's a mistake, please let me know.

If you already have DDR2 memory, go with the Am2+ system. If you don't have memory, go with the new AM3 system.
For $250 or less than $250 on Newegg you could get an Athlon II x4 + good mobo + good memory (I'm thinking 105 CPU, 85 mobo, 40 RAM). If you can get to the Microcenter in Boston (Get an Athlon II x4 + free or near-free mobo) you don't pay even close to $250 for your AM3 system. Note that you should only get CPUs, mobos and HDDs at Microcenter; the rest of the selection there (i.e. memory) is crum.

Great, I'm glad to hear it. I do already have DDR2 memory around, so I'll just go with the AM2+ system and save a lot of money. I just wanted to make sure I wasn't overlooking some major benefit of AM3. I'll probably hold onto this system until SB or Bulldozer come out if they blow me away.

P.S. I had no idea there was a Micro Center in Boston. That's awesome!

I only quickly checked their site's location list, and apparently there is one in the Boston area. You might be able to save on an Athlon II + DDR2 motherboard there too, though most of the deals are AM3/DDR3 I think.
