If that's the case, there was a small discussion that Ed, Peter, and I had regarding Chrome being such a memory hog, and there's a plugin you can install that disables tabs that aren't active. Don't remember the name of the utility, perhaps ask Ed (edwood) and/or Peter (iron_dreamer). The discussion was on Facebook, and I'm vehemently Facebook-tarded regarding searching older threads.
Once you do that, you'll definitely be fine with just about anything, if all you do is browse and email and whatnot.
Also, a trick I do before I learned of the utility (or rather, still do, because I haven't installed the utility yet) is copy my profile (%LOCALAPPDATA%\Google\Chrome\User Data\Default) to another directory (backup disk) (while Chrome is down), and then I can close all the tabs. If I want to come back to them later, I just swap this backup back in (it's all guitar porn and funny pictures and pics of cats and the occasional sexy picture of Oh Land and Kylie, anyway). And that way I don't lose any of my logged in sessions anywhere.
