I finally got around to installing an eVGA GTX 560 1GB I bought off of someone (I forget who, whatever...)at the LAN for my girlfriend, and just to test it out I booted up TF2. I watched the temps of this puppy skyrocket to 98C and backed out before I could even load a level.
Just a warning to all you fellow LAN goers...not everyone is honest when you ask them if the card works well or not. Really though, it's my fault for not testing it out first, but hey that's what I get.
