aliasing problems in Medal of Honor please help

Hi. I was curious on the matter of anti-aliasing in in MOHAA. I believe it's an open gl game. I love the game play, however, there are tons of jagged edges, or lots of aliasing going on. To me, this is really annoying, since when I played consoles like the PS2 and the Xbox I can barely see any of this aliasing going on in the first place. I put smoothvision on with my Radeon 8500 and put anti-aliasing in open gl up to4 and even 6x (with v-sync on/and with v-sync off) All that happened is I got slower frame rates with no reduction in aliasing. My question lies in this, is there no way this game can be as smooth and have little jagged edges like a console, or is there a way? All I want, is decent graphics with minimal aliasing. I thought the Radeon 8500 would knock the jaggies to minimal and create a more smooth, playable experience. I even tried upping the resolution to max but still saw noticable aliasing in the game. Basically, my two main concerns with PC gaming are this: frame rates that never drop below 60 no matter what is going on, and minimal aliasing(or jaggies). If anyone has some advice to kill aliasing in my current games, whether it be a tweak in this particular game or upgrading to a athlon xp 2000, I would greatly appreciate it. i really like this game, however the aliasing(or jaggies) is very noticable and tends to detract from my gaming experience. Would a GeForce 4 Ti4600 card with a AMD XP 2000 processor(and some DDRAM) make this game fly? I am at my wit's end and I just want a PC gaming experience that rivals a console.
