System Upgrade or rebuild options - Procrastination OD - Page 2

post #11 of 23
I'd say if you have the itch, go for it. If the itch can wait and you're going to spend that much money I'd wait for the new x99 processors to drop in 3-4 months (I think) and then rebuild. We're at the end of the current x99 CPU life cycle. I know that's a hard thing to say wait, because there is always something right around the corner and you can wait forever. If you were on anything older and lagging in current operations it would be a more pressing issue, but since you have waited this long, wait for the next Gen if you can.

Broadwell-E will release in the Spring. So its not too far away.

I was in similar situation
Upgrade chip $ or get a new chip, board, and memory $$$
3960X are going for around $250.00 on Ebay and O/C easily to 4.5 and up
4 to 6 cores and the performance is on par with a newer system

Counting all of your devices:
Xonar Sound Card 1x lane total
Ultra M.2 Takes 4x lanes total
U.2 takes 4x lanes total
780Ti SLI 16x lanes total minimum or 24x lanes maximum

That's a minimum of 25 lanes or a maximum of 33 lanes.

The difference? The minimum runs both GPUs at 8x8x (5820K) Speeds and the max runs them at 16x8x (5930K). (Note: At 16x16x with all of your devices you are using 41 PCIe lanes, aka over budget by 1 lane)

So you can still get the 5820K which is similarly priced to the 6700K and run all your devices.
Very true but I get Antsy at 3 years. So I just do GPUs. At 5 years is when its like screw it all in! New Build!

Beer,

if I want both GPUs running at 16x, the m.2 and u.2 drives at 4x each and the Xonar Sound card at 1x (41x combined) then I'm stuck with needing Socket 2011v3 which has 40, right? This still means one of the GPUs would be at 8x? From what I've read, SLI cards with one at 16x and 1 at 8x see very little performance hit provided the SLI bridge is in place, otherwise a 10-14% hit is seen. Wont the network controller and other SATA drives also use up lanes? 1 for Network and 4 for SATA drives, again, I think, so I'm going to see one GPU at 8x no matter what, unless I opt for a dual socket 2011 v3 and 80 lanes which seems .... excessive (ok, tempting too).

Does this make sense?

Oddly, I just ran GPUZ and it's reporting both cards are running in 8x right now, which is puzzling. Maybe I should look at dropping SLI and just getting one big new GeForce GTX 980 Ti ...

With the lanes issue, it seems the 5930k upgrade just isn't going to do that much to be worth it. I'm leaning toward either all in on a big new build or just do nothing but format drives and clean install.

Yes, all in or wait. That's my vote.

Getting a 980Ti isnt a good idea with 2016 video cards around.and the 3960x will perform better than a 3820 on same tasks either way gpgpu is the optimal accelleration on those tasks

That's because Sandy Bridge-E is stuck on PCIe 2.0. You will also see worse performance from M.2 and U.2 drives on PCIe 2.0.

So what I would do is keep the same setup you have but upgrade to a 4930K thats Ivy Bridge-E and comes with PCIe 3.0 It fits in your current board. Then I would just skip X99 all together and wait for Cannonlake-E. I would get the Intel 750 for your current board and get GTX 1080Ti SLI. Your 780Ti SLI should last until then.

EDIT: 780Ti SLI is FASTER than a single 980Ti just an FYI.

Beer,

Understood, on the SB-E restricting due to PCIe 2. I just found this while researching shortly before you posted. It seems the difference in performance tests are negligible between the two, in my scenario, but it's good to know.

Understood also that 780 Ti's in SLI are faster than a single 980 Ti but I figured a single card would resolve the PCIe bandwidth issue at 16x and I could put the 780 TIs on my back-up.

All the same, I'm leaning toward just doing the boot drive upgrade and waiting to do a full new build later in the year or early next. I may be stuck with that Intel 750 not being compatible with my RIVE without some big hoop jumping, however. Trying to figure that out now.

8X at PCIE 3.0 is 16x at PCIe 2.0
