Thanks guys, I was looking at the 1080 and I love the card, it wasn't the performance revolution over the Titan that Nvidia was promising but it's faster and cheaper which I appreciate. But I'm seeing in a lot of benchmarks all 8 gigs of its V ram are getting maxed out, but the Titan still has 3 to 4 gigs to spare so there's no loss of performance. Also I know this'll sound like such a noob thing to say but it's a bit worrying that only 2 and a half, almost 3 years into a new console generation Doom is already using 6 out of 8 gigs of memory on the 390, 390x, 980 TI and 1080 on its ultra nightmare setting, makes me wonder how far off it'll be before all 8 gigs are used.

Hey guys, I'm a first time PC builder, I've been involved with tech my entire life, I'm a computer science major, you get the idea, I have all the other parts for my system already picked out and purchased, but I'm having a hard time deciding between a new R9 390 or 390x or a used Titan X. The 390 or 390x would cost me around 300-340, the used Titan X would cost me 630. I love the Titan X, it'd be a dream to own one even though the 1080 is coming out soon, but it'd pretty much clean me out to buy save for around 200 dollars. The 390 would leave me about 400 after all is said and done. I'm going to buy whichever card will give me the best performance, what would you suggest?
