I get it that the mobo and ram could affect a cpu benchmark but I was looking at an AMD Athlon II X4 631 Quad-Core for a build for my kid because cpubenchmark.net had it at 4219 and only $69; putting it near an Intel Core i3-2120 @ 3.30GHz for $40 less. Then I looked at cpu world and saw the same processors at 2512 and 2052 for the amd and intel respectively. To make it more confusing the same intel chip had a benchmark of 1115 with a different mb, ram and vid.
Why the huge variation? How can I figure out what mb will allow the cpu to perform it's best?
My 7 year old son is playing low end video games like Roblox and Minecraft. Rigth now he is using a Dell Inspiron 531s that is about 6 years old. It has a Sempron 2600+ 2.0 GHz CPU, GeForce 9400 vid card, and 4 GB of RAM.
What I'm trying to do is build him a budget system that he can use and also I was thinking I would integrate some components that I might try to use on the next good rig; like the case, psu, ram and vid card.
