Hello,

I'm one day away from ordering a GPU. Everything was quite simple - replace my 760 with 970, the same old Corsair VS650 is enough. However, after the whole 3.5GB problem surfaced and after watching scary videos like this (670 vs 970 in Shadow of Mordor) - https://www.youtube.com/watch?v=kLs6YJrP5xU I really am clueless.

I currently have a single 1080p screen, but I'm thinking about replacing it with a 27" 2560 x 1440 (16:9) or a 29" 2560:1080 (21:9). So here's the problem. Surely, new games coming out in 2015/2016 will use more than 3.5GB even at 1080p - making the 970 a REALLY bad purchase when compared to the 4GB 290/290x ? As far as I understand, the size of 3.5GB is not the problem, it's the fact that it starts using the slow 0.5Gb which starts the stuttering ?

Lastly, if actually going for the 290 or 290x, is VS650 enough for any of them? What do I do in this situation (looking into the future) ? :(

Well, running Far Cry 4 and Watch_Dogs Ultra doesn't even quite reach it, but whenever it does reach (I go around messing with the MSAA X8 setting :p ) I see no stuttering at all, just lower framerates than what I'd deem as playable (high 40s/low 50s). By the way, when you get over the memory cap in a GPU it has to use system memory (really slower in comparison). What the GTX 970 does is use its 0,5GB partition, which is indubitably faster than the system memory (not as fast as GDDR5 though).
This means: GTX 970 3,5GB+0,5GB >>>>>> GTX Something 3,5GB.

If that was your only problem, I think you'll be satisfied with the answer :D.

I'd go with the GTX 970 nonetheless, or even better.... wait for the new R9 3XX series release, to see what it brings to the table (besides price drops which on its own is cool).

Why the 970? What about the PSU problem? And I really cannot wait, I can only buy the GPU in the next week max. That's why I'm asking for some opinions :(

You can't wait? Ok, well, if you're going to be playing on 1440p I'd still suggest the GTX 970, 'cause it's better than those 2 cards in terms of performance, noise, power consumption.... everything except the memory :p. If you're still worried and want to get the AMD cards (R9 290x definitely) I'd say the PSU is just fine. Realistically, on full stress the system will only consume 400-ish watts, but you always want some headroom.

I see You already own a 970. Does it get any weird stuttering as seen in the video after it goes over 3.5Gb? That's my biggest concern. I would buy it without thinking if it was just 3.5Gb card, but the extra 0.5Gb that slows everything down is what's scaring me.
