A friend I have been helping with his iMac G4 (well, actually you guys have helped me - thanks!), is giving me a graphics card instead of money, a 8800GTS. My question is, is my PSU powerful enough (not going to overclock), will my CPU be a bottleneck (going to change it after summer)? System specs to the left <--- Although, he does have several cards, and I have not yet made up my mind. But I just wanted to know since the card I'm currently using makes everyone laugh at me.. Thankful for any replies given.
