@ DukeSilver29: Fair enough, just checking on the upgrade bit.
A little more PSU output won't hurt, especially if you intend to push the system with some overclocking later on or just plan on holding onto it for some time.
Expect Nvidia GPU prices to be very variable from now on, they have just released info on their next gen of cards with actual availability being some time next month ( about the 20th ), the Amazon deal listed in Hellfire13s build has now expired for example, but it's highly likely similar, or better deals, will turn up on the out going cards in the next few weeks.
Wait or purchase now? Hard call, with no actual benchmark data to use we just don't know how fast these new parts will be although prices compared with the outgoing parts seem high ATM and it's highly unlikely these cards will be discounted for some time once they DO become available.
Right now Newegg has several RTX2080 on pre order for about $800 and upwards while their least expensive GTX1080Ti is <>$650.
Me, I'd wait and see how things pan out, if the new RTX cards are as fast as suggested it may be better to hold fire and grab one later rather than getting a 'bargain' GTX1080Ti only to find it's massively outperformed by a card that's 'only' <>$!50 more.
Note: All this depends on your system display, if you're on a fast HD monitor don't worry too much, the GTX1080Ti is more than fast enough, if you're rocking a fast 2K or 60Hz 4K display I'd really strongly suggest you do the CPU/MB/RAM change and hold off on the GPU upgrade for now.
