CPU/Motherboard/Memory Combo I am thinking to buy

[daddydave]

I want to upgrade what is now a computer I share with my wife. I want to replace the motherboard, CPU, and I want it to have 8 GB memory, keeping the rest of my

existing hardware

(Edited data generated by SiSoft Sandra Lite - I tried to cross out what I would not be using anymore after the upgrade)

The PC Part Picker site does a pretty good job and alerting me to incompatibilities, but I would like some human feedback as well. So do any of you see any possible red flags or glaring flaws in this 3 item combo at this price point? I see the motherboard supports DDR3-2400 memory but I thought I would save a bit there and go for DDR3-1600.

AMD A6-6400K 3.9GHz Dual-Core Processor    $62.99    -$5.00 rebate               
Asus A55BM-K Micro ATX FM2+ Motherboard    $53.99             
Kingston Black 8GB (2 x 4GB) DDR3-1600 Memory    $69.99

The new bulldozer-series architecture used by AMD is not very good. You would not feel that much of an upgrade despite a 1 GHz increase. If you play games though, the new GPU integrated into the CPU is much better than your previous one. If you don't play games, no difference would be felt again.

Check this out for a comparison.

As much as I'd like to see AMD have some glory (and more competition in the cpu market), nowadays I'd go for an Intel I guess. Try to get Intel Pentium G3240, or if  the budget is really really really tight, Pentium G2030. The only thing AMD has over Intel is the better GPU, and you'd need it if you play games. If not, go for Intel.

Ram speed has some limited impact on performance, but it is very sensitive to economies of scale. So DDR3-2400 does not provide a 50% boost over DDR3-1600.

Check this out, and decide what is the sweet spot for you.

Thanks, eleman, since I'm not a gamer, I will switch to an Intel setup, and thanks for the CPU recommendations. Still thinking about what memory to get.
