5MB/s is 40Mbps, way more than you can get out of g. It is however a bit pathetic for N.

G is 54Mbps if I'm not mistaken? But I understand that you can never really get the advertised speed.
Shouldn't I be getting ~30MB/s, with N? What am I doing wrong?

54 Mbps is the advertising number for g; the real maximum throughput is about 22 Mbps.
Same story with n; 300 or 600 Mbps (depending on antenna configuration) is the advertising number, maximum real throughput is ~130 Mbps (15 MBps) with typical antenna setups.

I see, so any suggestions on how to get the 130Mbps speed then?

Remove the obstructions between the iMac and the AEBS.

Yeah... There's two feet of air between the two. I would just use ethernet but there are no more open ports (FiOS router, PS3, FTP server).

Uh, if all I do on my iMac is transferring HD movies to my PS3, I would have bought a switch a long time ago. But that doesn't solve my 802.11n problem. I just noticed the slow speeds today when I actually went into activity monitor. I don't want to have wasted money on a router that doesn't do as advertised. I'd rather not wire every single computer, upstairs and downstairs, in my house to ethernet. If I wanted an uber fast wired connection, I would have snatched a 24-port router from work. I just want a good and fast wireless-N network for my house.

On the router you need interference robustness to be turned on. Also, go to g/n mixed mode rather than forcing 5 GHz n-only. I'm not familiar with the PS3. Does it actually have a decent wifi module? Finally, what kind of security are you using?
Other sources of interference include cordless phones, microwave ovens, and large metal structures close to the sender/receiver antennas. When my microwave is running my n speeds drop to ~2MB/s. Even though the router and clients aren't even close to the kitchen.

Alright so I just checked interference robustness, but it said that activating it may affect overall network performance, I'm guessing it means it in a negative way?
For the radio mode I put it on automatic which puts it in 802.11a/n - 801.11b/g/n, I'm using WPA2 Personal only for the security as I've heard that mixed WPA/WPA2 decreases performance.
And the PS3's WiFi module is not so spectacular since it's only b/g. So I have it hooked up via gigabit ethernet. I've noticed when I transfer/stream files from my Windows PC which is also hooked via ethernet, the speeds are blazing fast, so there's nothing wrong with the router or PS3.
Besides a cell phone being on, I can't think of any other sources of interference that's anywhere near the computer/router.

Have you tried it with wireless security turned off?

So why'd you buy an Apple Airport Base Station?

If you have interference, IR will help performance/stability. If you don't have interference, IR will hurt performance. Think of IR like driving slower in the rain; performance is down, but you're more likely to arrive instead of crashing.

Use 5Ghz n-only for best performance.

Just tried it, speeds haven't seemed to change

Because I wanted an 802.11n wireless network for my house. I could have bought a netgear or d-link and be done with it, being an apple fanboy, I naturally bought an AEBS.

I see, I'll see how interference robustness will affect the performance. I had it turned off before because I never really thought I had any interference.

So was the setting I had it on in my original post the most optimal one?
