On my old video card, a Nvidia GeForce 9400 GT, I was averaging 180+, the highest I ever remember seeing it was well over 200 and that video card fried. I never knew that Sims 3 had a FPS issue until it was too late, I played one other computer game and everything was fine. When I noticed what was causing the problem, I stopped playing Sims nearly all together. This was before I was informed of mods, bypassing the launcher and all those other nifty tricks. Every once in a while I'd load the game up and play for a bit, I figured if I didn't play too long the card would be ok. That was a big mistake, eventually I had to take the side panel of the case off and have a box fan cool my card down whenever I played anything.
The night before we got new computers I was playing Sims and the graphics started stuttering really badly, eventually I gave up and went to bed. The next day when I was transferring parts into my new computer, I pulled my video card out and parts of it just fell off. The card had heated up so badly overtime, that it had became brittle. The card was only about a year old and wasn't under any warranty because I forgot to register it.
Now I have a Nvidia GeForce 9800 GT, I use an fps limiter every time I play Sims and I've had this card for just over two years. High FPS is a great thing but not excessive FPS, my Sims never go above 35 which is on the lower end and I'd never really want nor need over 60-70. I'm much more happy to be able to play than have overly high FPS in a game that renders like Sims, not to mention it's not costing me $150 or more each time it fries a card.
