CaptainTom :
I'm sorry but I am just gonna be frank and say that the GTX 770 is the worst choice in the high end right now.
-The 280X is cheaper or the same price while offering equal performance across the board and 50% more VRAM. This VRAM is needed in recent games and will be in all future high end games.
-The 290 is only $100 more and offers double the VRAM and A TON more performance.
I would disagree on these points. I've been looking at the R9 290s and the R9 280x for a couple months now and tracking their prices.
The R9 280x sits around the 400$ mark. The R9 290 sits around the 520$ mark. The GTX 770 ranges from 330$ to 400$+.
The 770 and the 280x perform similarly, but if you plan to dual GPU later on I would opt for the 770. Otherwise, take your pick between these two.
The R9 290 is a tricky topic because at its initial MSRP, it was meant to be sold at around 400$. Due to cryptocurrency and economics, retailers have brought the price up to above 500$. With the recent release of some aftermarket solutions, that price is 580$ as of today on Newegg.
I've personally been waiting for the R9 290s to go down in price, but it seems to be staying quite steady. As for a proposed solution to this thread, I would say go for a good GTX 770 or a cheap R9 280x (if you can find one).
