1100T bottleneck? Upgrade suggestions...

post #1 of 38
Thread Starter 
Alright first post! Go ahead and yell at me for posting in the wrong place or not following the forum rules, but I tried to be sensible in my topic location. I have a specific question about my build, and I need some help figuring out if my build is going to hold back some significant upgrades...

So I just bought a Overlord Tempest x270oc 2560x1440 120hz capable monitor and it is going to arrive in a few weeks... I am trying to get my build as optimized as possible in an attempt to ensure that I can handle the increase in resolution, and attempt to maintain high FPS to benefit from the 120hz. I want to try and break 60fps for all the games I play regularly, and I want to try and play at maxed out settings or tweaked settings for the games.

Let me post my build:

Phenom 2 X6 1100T at 3.8 (Air cooled w/ Hyper 212 evo push pull)
Asus Sabertooth 990FX
2 EVGA GTX 670 FTW 2GB (2 way SLI)
16GB Kingston HyperX rated for 1600 (but for some reason crashes at that speed - stuck at 1333)
SSD Main Drive
1000w PCU

So first I started looking at adding a third 670FTW, however I saw that scaling sort of sucks with 3 way sli for most titles, and I also saw discussion about a potential CPU bottleneck... Since I am trying to increase my framerates (or at least max with what I have or w/ upgrading) I discovered that perhaps my limitations are with the CPU. A year or so ago when I upgraded my rig, I was sort of stuck in AMD land- I upgraded a "bad" motherboard- but it turned out that I still had issues so I bought the 1100T to replace my old Phenom 2 X4. I skipped FX altogether because of the bad rap it was getting at the time.

So I am a little stuck. I could upgrade my entire build to an Intel solution, but I am saving that for next year or so. I need to get the most juice out of my 1100t as I can, and if anyone knows if I am going to experience bottleneck on games or how to optimize my build for 1440p gaming, please offer suggestions. I am a little frustrated at this point. Sadly, I have the 2GB 670s which limit me a little... Wish I had the 4GB for all the Skyrim modding I do... Thoughts? Questions?

The higher the resolution is, the less likely your CPU is to bottleneck. Let your monitor arrive, see what's going on, I wouldn't upgrade just yet.

So what you are saying is the monitor resolution doesn't stress the CPU but it stresses the GPU? I can potentially see that, but a big question in this case would be if I would get any benefit from a third 670... Or if I hit any bottleneck in doing so.

Most likely you will bottleneck the third 670 with your current build. It would still be a improvement, but not worth it.

While you would be bottlenecked some don't think I'd be wise to upgrade at this point with Haswell around the corner. My old Ph II @3.7 bottlenecked me with SLI 460's @900 (faster than a stock 470) and going 2500k raise my mins and fps across the board but Thurban is not Deneb unlike most like to think and is in fact a bit faster with a better NB so you should OC that if you haven't to maybe 3k or something to see real gains.

Aside from overclocking the NB I would say hold out until Haswell if you want to upgrade, I normally don't believe in waiting for the next big thig (as you'll always be waiting) but we've seen the new mobos (hear about USB issues tongue.gif ) and their impending release is just over the horizon.

My vote is to hold onto your CPU for now and re-evaluate later in this year, if you don't choose to go Haswell then there will be so many people selling 2500k/3570k/2600k(7)/3770k's as they're upgrading you will also be able to save cash and buy a nice Sandy/Ivy cpu/mobo combo on the cheap and save a few hundred bucks there. thumb.gif

If everyone universally agrees that the 1100T would bottleneck, I need to overclock to 4.0+ though I don't think I could survive a Prime95 run overnight. Maybe, but not sure. I wish I could test this myself without spending 400 bucks on a 670. tongue.gif Benchmarks always run under Intel builds.... That I have seen.

My current overclock is just a multiplier because I am a little afraid of tweaking my bios settings... Bad experiences in the past. I have serious stability issues from an unknown reason.

I will do some research on the topic and try anyway.

Default atm. I am going to have to tweak it tonight. My overclock is purely a multiplier... I had issues when my ram timings started getting strange. At least I want to believe it is the RAM.

Leaveing your Northbridge at stock is your problem, Set your CPU-NB Voltage to 1.28V and set your Northbridge speed between 2800 and 3000MHz, your bottleneck should be gone thumb.gif
