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.
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
