I share your pain, I was perusing the EVGA and Strix 1080ti with glee, and the urge to click buy with an Omen X35 or similar was very hard to resist.
I have no problem with price drops a few months down the line, or new card releases, it just means good second hand prices for SLI rather than a new gen. But when you can buy the same card 6 weeks later for almost half the price, it gets me right in the feels.
Keep me posted as to what you do mate, I can't see NV not releasing a least a top end card in 1H, so I'm watching carefully!
