I'm not going to bother doing a top ten or whatever, because I would never be able to make my mind up with the order of them.
Crystal Castles, electronic duo from Canada, mixes 8-bit, electronica and distorted female vocals. They're not as amazing or mindblowing as some people make them out to be, but I do enjoy listening to them. They were my introduction to chiptune, and they were a refreshing change to most other electronica I listened to.
Saying that, the fan compilation of material (AKA TrashTrashTrash) is better than the official album. Oh well.

I downloaded his other albums, and found just how versatile he is. From house, ambient, industrial, to chiptune. It's all worth giving a listen. And he releases new EPs every few months. Great artist.

Fizzy Dino Pop, mixes chiptune with rough shouty vocals. I only have one EP from him and I've managed to accumulate 304 listens for him on Last.fm.

Girljoy, makes dreamy sounding chiptune, that just reminds you of the NES era. A lot of her songs sound like they actually belong on older video game soundtracks, something that not a lot of chiptune artists can pull off.
She's stopped making chiptune now, and deleted her Girljoy myspace, but she's under the name of "Misfemme" now and is making dirty electronica. Think Peaches, only with more creative song structures and sounds.
http://www.myspace.com/misfemme1-800-ZOMBIE, two teenage girls from Texas, who rap about bitchy schoolgirls, MySpace and Bob Saget over some Nintendo sounding beats. They don't take themselves too seriously a lot of the time, but they're good fun to listen to.
http://www.myspace.com/1800zombieTalk To Animals, the solo project of Aimee from 1-800-ZOMBIE. She generally makes electronica, but she's tried her hand at chiptune and drum and bass, pulling both off incredibly well. The production on her songs is great, and she's only just turned 18. Well worth checking out, she was a big influence for me to start making my own electronic music.
http://www.myspace.com/talktoanimalsThe Pipettes, good simple pop music by three girls from Brighton. I've known about them for at least three years now, but I didn't have the album until the summer of this year. Such fun to listen to.
Unfortunately, there's been a few lineup changes this year, but apparently they're releasing a new album soon, so let's see what happens.
http://www.myspace.com/thepipettesBjork, okay, I've known about her for ages now, but I never had a full album from her until this year. Vespertine, Medulla, Homogenic and Post are great, and Volta is worth checking out too, but it's definitely the weakest album she's released.
She's a huge inspiration to me, and constantly evolving to drop something new and exciting each time.
http://www.myspace.com/bjorkGirl Talk, only have Night Ripper, but woah does this person have talent. Making a full album from sampling other people's songs (the sample tends to change after about every 15 seconds in each song by the way) and still making it sound fresh is no easy task, but Girl Talk pulls it off well. Mixing M.I.A. with Kansas and Fleetwood, Smashing Pumpkins with Kelis and Gwen Stefani, you really need to hear it to get the idea.
http://www.myspace.com/girltalkBlonde Redhead, I'm not even sure how to go about describing their sound. It's moody and dark, while still sounding pleasant to listen to. The haunting female vocals really do set them apart from a lot of other bands.
