Gaming router suggestions?

Not sure on what router to use mate but I can tell you your prob straight off if you are using wireless. DONT!
Lol, I used to run a wireless connection for my games and got constant lag, dropped connections, high pings etc etc, (nothing more frustrating than crashing a packed blackhawk in bf2 and getting loadsa tk's) So I switched to wired CAT5 and immediately my ping rate improved, I didnt drop from games and lag became non existant. If you dont want to string a big fat cable through your house (I find 20m does the job nicely) I suggest you look for a 200mbs powerline kit.

My mate swears by 2-wire products.

As a side note your PC will have some issue with UT3 i suspect, its a pretty ropey game at that spec

Dlink DIR-655. I upgraded my old Wireless G router to the model I just stated. Even though my wireless G router had a high gain antennae that was wall mounted my new router still blows it out the water. For my PC I keep it connected (gigabit port on router and computer). My PS3 and Xbox 360 are on the opposite sides of my apartment as the router. With my old router my signal strength hovered around 75%, with the new router it never drops below 95% usually staying at 100%. I never have trouble playing any games even though I constantly have multiple wireless devices connected and my computer running as a full time media server. (PS3, Xbox 360, Pocket PC cell phone, 2 Laptops all connected wireless), 2 desktop computers and sometimes another laptop connected thru the wired ports.
