nhanphan1990 Posted June 30, 2016 Posted June 30, 2016 (edited) Hello everyone,It's been a long long time since I last started a thread in this forum I will be parting with my i7 4930k rig in July. At 1st my plan would be to upgrade to X99 platform with a GTX 1080. However, this is cut short because I need to adjust my budget for a new car. So I have to choose between a new motherboard + CPU + RAM or a new graphic card.With my old GTX 285 being irrelevant and I heard that the new Kaby lake will use a different platform (unconfirmed of course), I decided to go for a GTX 1080 with a water block on it (just my hobby, I know the performance gain isn't worth it), and I will use my brother's old rig, an i7 990x@ 4.4 Ghz on a asus WS-E motherboard.I game at 1440p and 100-120 fps. My question is, will an i7-990X @ 4.4 ghz, along with PCIE 2.0 bottleneck a GTX 1080 at that resolution and framerate?Sorry for the long post people, looking forward to your suggestions P/S: I know a GTX 1080 is not really an upgrade from my GTX 780 ti SLI, but I'm done with SLI and yes, I am aware that AMD vega is around the corner (rumor of October release); BUT I need to enjoy my gaming life right now before it's over by next summer (going to med school and getting married ) Edited June 30, 2016 by nhanphan1990 Share this post Link to post Share on other sites More sharing options...
Braegnok Posted June 30, 2016 Posted June 30, 2016 I would think your 990X @ 4.4 will be fine running todays games with GTX 1080 @ 2.0X16,.. the i7-990X is older 32nm chip with ddr3 1333 memory but single core performance is not far from i5-6600K. http://cpuboss.com/cpus/Intel-Core-i7-990X-vs-Intel-Core-i5-6600K Share this post Link to post Share on other sites More sharing options...
Fight Game Posted June 30, 2016 Posted June 30, 2016 Doubt it. I also doubt anyone has tried that combo to find out though. Share this post Link to post Share on other sites More sharing options...
road-runner Posted June 30, 2016 Posted June 30, 2016 The 1080s seem to fold fine with x58 platform and i7 920... Share this post Link to post Share on other sites More sharing options...
nhanphan1990 Posted June 30, 2016 Posted June 30, 2016 Thanks for your input guys. I was worried about the weak(er) single core performance of the 990x conpared to the current generation, and on top of that, is the bandwith limitation of the pcie 2.0 Well, I think I gotta try it out to confirm then. Hopefully with DX12 games will start using more cores effectively Share this post Link to post Share on other sites More sharing options...
