Athlon II X4 640 vs. Phenom II X4 945

I am wondering whether to get an Athlon II X4 640 or a Phenom II X4 945. I will be running a 5850 w/ this system. The Athlon II X4 seems to be about the same performance for 30 bucks less. Worth it? I am on a VERY tight budget, and any money savings would be stellar.

  1. Tight budget is exactly what the X4 640 is for.
  2. So no bottlenecks? I am going to crossfire down the line.
  3. Compared to I7 there will be a bottleneck but nothing that the L3 Cache on the Phenom is going to solve.

    I have a phenom II 945. I am currently sitting on a +500 mhz OC. I can't hit 3.6 stable. Honestly, I am not thrilled. It's too close in price to a BE, and not a very good dollar/performance when compared to a athlon II 640.
    However, with that said, if you have no plans to OC, than the 945 is great, because it is the top line amd with less heat. With a cooler master tx3 and all the power savings features, mine idles around 27 celsius (slightly above room temperature) and might hit 35 max with full fan on prime95 stress test
  6. For the record though, i wish i had gotten a BE
  7. I guess I'll get a BE. There are some great deals out there.
  8. Hows about a Phenom II x3 740 Black Edition!?!? New Egg has them OEM for $89!!!

    I keep my 955 on 3.0 GHz. Tried 3.6 and saw no difference but in benches. Anyway by the time the 945 will be obsolete so will the BE.
  10. Sounds like I'll get the Black Edition. If anything is going to be obsolete, I might as well get the one that will overclock much more and be less obsolete than the others down the line.

    It is a great triple core CPU with a unlocked multiplier!
  12. Get the quad. You will need it in the future.
