Hi right now i have a MSI NX 7600gt grapic card and a 450W powersuppyer and im getting FPS laggspikes wen i go into populated places and i cant enter major citys,

So my solution is to get a nVidia GeForce 8800GT, 512 MB and usign the old one via SLI (or jsut skippign the old one compleatly)

Now i have 2 questions:
1. Does it work to SLI thous grapics card or do they not liek each other? XD
2. Is my powersupply big enough?



ram 1gb, gota update that too :S
cpu is amd dual core +3200
