Allocating RAM for modded client and server
Okay guys, I have a rMBP 15" 2.8Ghz 8GB RAM. I was thinking about playing modpacks. Anyways I want to play this modpack with my friend. How much ram do I need to allocate for my client and server? I learned that server ram isn't so important if you are using few chunks.
I have a little question too. Which one of these needs to be good for modded minecraft, CPU GPU RAM.
Modpack: Hermitcraft Modsauce (170 Mod)

If you are using high resolution texture packs then this will hit on your grafics card. If you are using a lot of mods making block updates (like f.e. complex electricity systems then that will hit omln your CPU. Every mod adds a bit of RAM needed, mostly mods adding new blocks and new data to existing blocks. Multiply this arbitrary value with all loaded chunks. For the server, two people far away from each other is more RAM the 6 people on one spot. For the client, only his own view-radius counts.
A tipp for the client, don't give him to much RAM as then chunks get unloaded more lazy and there will be more CPU-spikes when garbage collection kicks in. And for custom world generators, you have to increase your heap space.

I've found that the client and the server will run you upwards of 4 GB each. That's on a two-person Yogscast Complete server (on a 64-bit machine) which runs a lot of mods. I usually use Sphax texture packs as well. You may be able to run it, since it doesn't always get that high, but you'll have to monitor your memory usage
