Was originally wanting to get the 2080 ti, but for pricing reasons that is not going to happen. Been looking at gtx 1080 ti lately and noticed that they are quite cheap now (most particularly the EVGA gtx 1080 ti SC2) for just $650). the RTX 2080 is said to be $700 for founders addition so getting an after market version of that would maybe an addtional $50 to $100. 1080 ti has 11gb of GDDR5X while the 2080 has the faster GDDR6 VRAM, but only 8 GB of it.
So what I'm asking is would the difference between the two cards be great enough to spend less for a GTX 1080 ti now or would it be better to wait for the RTX 2080 to come out and spend more? (From a gaming perspective, which would be better for 2560 x 1440 gaming)
