Which one are you finalizing? R9 290 CF or R9 290X CF?
If its R9 290 CF, then here's my experience with the single R9 290 (Sapphire Tri X) on My 4k (Asus 60Hz 1ms):
Hello!
Firstly, yes its 60Hz. Mine is just a week old, so don't expect crystal clear info on each and every aspect, I'm yet to explore them. I'd try my best to be transparent.
So I bought it about a week ago. Assembled my rig with it. It booted, no lag nothing.
General performance: Well its perfect! Its acting like I am on a FHD and not 4k. By that I mean no lag, no clutter, crystal clear performance.
Video Streaming: Oh its absolutely amazing. tried some 4k videos from youtube, and my god was I amazed!
Gaming-normal: Easy to handle games work without ANY sort of lag or error or anything. CoD Ghost was ice cream. Even Watch Dogs was not that bad, yeah some lag on Ultra but visibly clear on very high, and lagfree on high. Didn't expect R9 290 to be so good! I was actually thinking of CFX but I don't think I'll need it for a while. GTA V no lags.
The above games I could run at 35-45 on Ultra and 45-55 on very high. 60+ on high. What a performance R9!
Ultra gaming Multiplayer: So it was the hardest test, with BF4 and Far Cry 3 at ultra on Multiplayer.
I didn't have Crysis 3 so couldn't check.
Ultra: Both 35-40 FPS on Single player.
Multiplayer: BF4 got to about 35 FPS thanks to multi core optimization. FC3 stuck at around 30 FPS. NOT BAD!
VFX: I built this PC so that it specifically suits my VFX and Video rendering needs. I'm VFX undergraduate and have seen and worked with more cards than I could possibly name.
The experience was really good, the RAM was also crucial here, thanks lord I have CL9 Corsair Dominator Platinum @ 1866MHz. No lags, no screen drops, no difficulty in hovering my mouse around lol
😀
When I was converting and rendering heavy landscapes, the card was running well and I think I was able to open Chrome and listen to some music.
The display is more crisp than my eyes lol. Its so huge (pixel count wise) and fast my eyes envy it hehe
Not a single lag in any sort of streaming or multi tasking. Very bright and vibrant display. I'm in love with my rig.
Overall: OMG what you waiting for!
😀
That's a PM I sent to one of the members here on his request to write up a review of my R9 290 on 4k.
Just imagine what 2 R9 290s will do! Absolute wonder!
50+ FPS on latest titles on ultra is sure. Maybe even more
😀
Also, I just wrote a tutorial for 4k vs 3XFHD, you might want to check that out:
