Do I need a new router for peer-to-peer?

Whenever I'm using a torrent I usually have problems with getting a high download rate regardless of the amount of seeds avaliable. I was therefore thinking that maybe it was the router that was causing all of the problems, and was wondering if getting a better one might fix the problem. The type of router I have now is a Speedstream 6520. Also I tend to use BitComet, and my half open limit is set to 50.

I have already been to Newegg, so I have seen several of the different types of routers avaliable, the only problem is, I can't really make heads or tails out of which is the better one to get. If anyone has any advice on this matter please let me know.

Port forwarding on some random ass port you dumbfuck.
