Well whenever they feel like releasing this multiplayer beta, you guys will be the first I'll notify. I went ahead and bought a Intel Quad-Core processor just because of this game (and mainly that all the newer games will utilize this awesome piece of technology). Probably the best $500 I've spent in awhile.
Depending on how it ends up running, I might increase my RAM as well (running 1 gig right now). But I recently upgraded my card to a Radeon X1650 with a 400 watt power supply, and my processor's a Athlon 3300+. Then again, I've noticed that if I ever run minimum requirements on any game, the game's framerate is still unplayable. I'll definitely check out that beta to make sure I can run it before I buy it, even if I have to run it on minimum settings.
