So I'm in the middle of a major cleanup and overhaul of my system and when I took my TXP's out I noticed what looks like scorch marks on the SLI fingers. I spent some quality time removing the black and ordered a new SLI bridge. I also have some rust in the cooling chamber of one of the cards. This is after my initial cleaning. Any thoughts on how this can affect performance? The black marks were limited to 1 side of the card. I'm very displeased with the rust since I spent enough on those EK blocks.
