I just recently tried wifi again after many disappointing attempts and I have to say this time is no different. I moved a computer to another part of the room where I didn't want to run a wire so I picked up a PCIe wifi card. Its a D-link 802.11n Xtreme card (4/5 rated on Newegg) just like my router. My LAN throughput is now a blistering 3MB/sec. And it needs to be kicked in the butt to connect upon waking the computer. Brilliant. That's OK for web browsing but useless for file transfers or media streaming.

Then you've configured something wrong. I'm sorry, but unless there is a lot of interference between you and the router, there is no way you would be transmitting at 3 unless you have something set up wrong. I use a Cisco Aironet 1250 (yes, I'm that much of a nerd to where my home network looks like it's a company) going to other wireless n cards, and my typical throughput is anywhere from 200-270 Mbps internally and the full 50 Mbps externally. The reason for the slow external speed is because that's all the bandwidth I'm given by my ISP, thus making them the bottleneck.

Well tell me what I could have possibly mis-configured considering the driver doesn't really give many options.
My guess is your issue is with the router, not with the actual NIC card. And again, you can't completely discount the fact that you might have some thermographic issues to contend with or other RF interference that is inhibiting your throughput. Also of note is whether there are other devices connected to the WAP and what frequency and band (a/b/g/n) those devices are using. Do you have CMSA/CA enabled? There are a lot of possible culprits, but transmitting at 3 is clearly an issue with either hardware or configuration, not a limitation of the technology itself.
I never said it was transmitting at 3. It says its linked at 130Mbit but the actual throughput while copying a file is only 3MB/sec or less. Both ends are 802.11n, latest firmware and drivers and no other wireless devices in use.
Again, there's a bottleneck somewhere. If it's not in the router (and I think it is), then it has to do with how the data is being transmitted over the RF. Something isn't right with your configuration, though. Unless (and this is a longshot unless you're using old technologies) the bottleneck are your actual devices themselves, not being able to process the transfer any faster than they are.
My advice to you is to start by examining the data transfer to see if the session is windowing properly, and if it is to then make sure that you aren't getting a lot of re-send requests. There are a million things it could be, but this is the place to start.
If this is a desktop, I suggest a wifi card with an external antenna connected via a wire. Most wifi cards use an antenna attached to the card, which means it is near the floor, and surrounded by the metal chassis of the computer. If the computer chassis is between the antenna and the router, signal quality may be poor. An external antenna can be placed in a better location.
One guy said he lived in an apartment complex where most people had channel 6 or channel 11. He changed his channel to 1 and had a nice signal.
