so i am getting a new comp....

• Intel Core™ i7-5820K Processor
  
• 8GB DDR4-2400 Memory
  
• NVIDIA GeForce GTX 750 Ti 2GB (x2)
  
• ASRock X99 Extreme6 MB
  
• 1TB 7200RPM Hard Drive + 120GB SSD
  
• 24X DVDRW
  
• Win 8 64bit OS

as seen, i am getting two vid cards. does MWO support SLI yet? is it worth getting the two vid cards??


thanx

750Ti's cant go in sli anyway, so it won't work anywhere.

[xWiredx]

SLI starts at the 760, as Flapdrol said 750 Ti cards cannot be put in SLI.

SLI does work, but it has some issues. I went from 2x 660 Ti to a single GTX 980 just to avoid the SLI issues and I am much happier. Instead of spending that money on 2 750 Ti cards, spend the extra $50 and get a GTX 970 (unless you're going with a 4K monitor, then you might as well go with a Radeon 290X or GTX 980).

Also... only 8GB of DDR4? You are aware that DDR4 goes up to quad-channel right? Dual-channel DDR4 will be lacking in bandwidth enough to hamper overall memory performance (and probably shave off a few FPS) due to the higher latencies (and only 2400? Man... I'd go at least 2666 especially if you're not going quad-channel right now).

[Oderint dum Metuant]

More to the point.

Why would you spend so much on a new PC to go into the DDR 4 era and go SLI and try to go as low as the 750TI's (that don't do SLI anyway)

970,980 or 290X at that point

[Max Immelmann]

well guys, thanx for the replies. to answer you all, i do not know much about computers. the specs i posted are a pre-built that i found on "ibuypower.com" with the exception that i added the 2nd vid card.

ok, so go with a nvidia 980 vid card, fine, will do
but all this concern over the ddr4 is beyond me. i have no idea what you are talking about.

[Flapdrol]

those cpu's can use 4 memory modules in parallel, for 4 times the speed, minimum module size is 4GB, so the machine will only have 2 modules.

I don't think it'll make that much of a difference though.

[xWiredx]

Eh, at 2666 with the stock latencies in quad-channel, DDR4 has been shown to perform slightly worse in some applications and slightly better in others than DDR3-1866. Since we know that other Cryengine games give about 1-2fps difference between DDR3-1333 and DDR3-1600 (and another 1-2fps going from 1600-1866), and typical gains are 1-2fps for most games going from DDR3-1600 to DDR3-1866 (and another 1-3fps going from 1866-2400), it's logical that with dual-channel DDR4 you'd probably lose 2-4fps over a cheaper setup using DDR3-1866 in dual-channel. DDR4 has the bandwidth, but with it's higher latencies the performance is definitely lower. Quad-channel bandwidth is huge and the effect of higher latencies becomes far less noticeable. I'm running quad-channel DDR4-2750 and the effect of higher latency is almost nil at this point. DDR4-2800 is where it starts to pull ahead, and DDR4-3000+ is where you actually see gains. Games generally don't seem to benefit beyond 2666, though there are probably a couple of exceptions (Starcraft 2 is probably one of them).

Do not build an SLI rig with MWO in mind. You will get WORSE performance when running SLI. I currently have a SLI GTX 780Ti and 5820K @ 4.5GHz setup and if I enable the second GPU, my FPS drop by about 50% and the game also stutters a lot. with 1 780 Ti @ 3440x1440 I can average 80-90FPS on very high and PostAA. All other games I have tried (Crysis 3, BF4 and SC2 etc), work fine with SLI.

Basically SLI is completely broken in MWO, in fact I do not even know why its enable at its current state.

i have already decided to go with a gxt 980 instead. also, 8gigs of ddr3 1600 mem. thanx for the help all.

Good choice.

DDR3? DDR3 doesn't work on X99 platforms...

I hope he either meant DDR4 or is going to a Z97 platform.

I would switch out the Kingston SSD for a Samsung EVO 850. I would also make sure you are not planning on adding a second GTX 980, because 600W PSU would not be enough, especially if you plan to OC. Also 8GB to me would be a minimum, for just gaming you are okay. But if you plan to have other applications open in the background I would opt for 16GB. Both Gskill or Corsair are good choices.

[Max Immelmann]

samsung is not an option.

i record video while playing. so do you think more mem is needed? no. i am not sli 980!!! WAY to expensive! lol

If you are recording video it wouldn't be a bad idea to go with the 16GB. Personally I would prefer to have that extra buffer. Also this way you will be set into the future.

What are your options for SSD?

You don't need 16GB of RAM to record Video.

8GB will be plenty you'll be paying money for it to sit there and do nothing

But then your wasting money going with Ibuypower..

Building the system yourself would be a much better option then ibuypower but maybe the OP does not have the experience. I use up 16GB with a web browser and a bunch of tabs open. For just gaming and recording only, then yes 16GB is not necessary but I also do not want to worry about being constraint on what I have running in the background.

If you use 16GB with web browser tabs, you're doing something VERY wrong. I have multiple tab groups for work, each with 10-20 tabs, and Firefox never reaches 3GB. In fact, the only way I've ever managed to utilize more than 8GB of RAM at a time is with VMs or massive development binges. Even music production hasn't pushed beyond the 8GB envelope for me, and I shuffle between 3 DAWs with a decent amount of pretty heavy plug-ins.

OP definitely doesn't need 16GB of RAM. I might go with DDR3-2133 or DDR3-2400 instead of 1600, but that's just me trying to squeeze every single ounce of performance out of something.

With Chrome x64 and 30-40 tabs open, you would be surprised how much memory it can take up. It really also depends on what web pages you have open, some will take up a good amount of memory. Generally when gaming I would not have that many tabs open, but other items like Origin, Steam, Teamviewer, VMware etc would be running.

Again if the OP is only gaming and recording, then 8GB would be enough.

Memory costs are not that much more, maybe an extra 60-70 depending on speed, when the system cost 900-1000 that is not a big difference. Now if upgrading the memory prevents purchasing a better CPU/GPU, then I would stick with 8GB.
