Would the amd 1090t bottleneck the amd 7970?

In general, no. Compared to just about anything Intel Core i series, yes. I could not find it right away, but Tom's did a recent article about AMD CPUs causing some sort of bottleneck.

One other thing to look out for is if you play any older DX9 games, you'll likely be disappointed. It seems the new cards have some sort of issue there. DX11 games should be fine.

well i did and the bulldozer depends on your use beacause how it works poeple would say go with tthe 1090T but i would get a FX 4100 and a H70, H80 or H100 and overclock it to death but whatever the bulldozer ones will not bottleneck it but people say they suck but they really work very well for me so it's your choice. on dirt 3 i saw all 8 threads being used like 1/8 of the thread usage so it runs epicly then benchmarks say so if you want to either overclock a 4 core bulldozer, get a 6 core bullzoder and maybe overclock it a bit or get an 8 core bulldozer but anyway ive used it on games and it works fine i have no idea how benchmarks can say such resaults i have a FX 8120 and it works almost like a 8 core sandy bridge but i think the bulldozer only does bad while your rendering things.

The Bulldozer would actually be worse. Take a look at Tom's latest gaming hierarchy chart. You'll notice that even low end Sandy Bridge chips such as the Core i3 series, beat anything AMD has to offer, even when the AMD is overclocked(refer to the first page of the article. http://www.tomshardware.com/reviews/gaming-cpu-review-overclock,3106-5.html

As a long time AMD fan(since 386dx40), it makes me sad. But I am also pragmatic. I go with whatever is best for my situation whenever I build.

So your telling me that a core i3? dual core would beat the 1090 wow that makes me NOT wanna get the 1090t AT ALL

but i mean i can get the 1090t for 149.. so yea

The reason to get the 1090t would be if you had apps that could take advantage of all those cores. In gaming, I cannot think of any that I play, although I am sure there are a few out there. Keep in mind also that the Core i3 is multi-threaded, so it acts basically like a quad core. Also, where I live, I can get them for $99 all day long at Microcenter.

I would also note the disclaimer at the bottom of the first page of the Tom's article which states that the comparisons are for gaming only. If you factor in other things such as video encoding/editing, 3D modeling, or other multicore friendly apps, then the advantage would swing towards AMD at least in terms of price.

Do you even realize how aged all those single threaded games are? The entire article was catered for intel.

nope thats wrong the phenom is much better then a i3 i dont know what he's talking about

Im just gonna tell you the awnser of what you asked

NO the phenom is far from being able to bottleneck something like that but the only reson why people say the bulldozer iss so bad is beacause how it runs but it's fine in gaming and really works but benchmarks just tell you basicly for example the time it took for the cpu to add 1 to 10,000 numbers whichs really dont do much for gaming and for the price of a 1090t vs i3 or i5 the 1090t will win for overall be better for that price.

first im talking about non gamig bencharks
second gaming bencharks depend on the gpu to
third find the same setup with both CPUs on a gaming benchark that uses cpu power to then ask me

i5-2500k = $180

Non gaming benchmarks are irrelevant to this discussion since the OP is building a gaming rig. Not all benchmarks are GPU dependent. It depends on which game.

I am afraid your third sentence did not translate well so I cannot respond.

Here is the Deal.

The 1090t WILL bottleneck the 7970 in some cases. The main ones of concern would be Elder Scrolls: Skyrim and Battlefield 3 (Multiplayer). Both these games are fairly poorly optimised for CPU performance and only fully use 2 or 3 threads, as a result the lower single threaded performance of the 1090t will cause the bottleneck.

In comparison the i3 2100 has excellent Single threaded performance, and although it only has 2/4 Cores/Threads, games that are out these days barely utilise that fully (Although 4 - 6 threaded games are becoming more common). As a result the i3 2100 performs better than the 1090t.

Bare in mind that an i5 2300/2400/2500/2500k will outperform a 1090t in all cases including the heavily threaded applications due to the fact that its single threaded is higher even than that of the i3 AND it has twice as many cores.

Unfortunatly this leaves AMD without a recommendable CPU at any price point - the Sandy Bridge CPU Architecture is simply too strong - Even the Dual Core Pentiums are going head-to-head with the Phenom II 955 and keeping up.

And most people forget this little comparison but Intels Single Core Celeron G540 @ 2.5Ghz is much faster than its price point counterpart the Athlon II 250 Dual Core @ 3.0Ghz.
http://www.xbitlabs.com/articles/cpu/display/celeron-g540-g440_6.html#sect0
This helps prove the point that single threaded performance still matters and Sandy Bridge has LOTS of it.

TL: DR - 1090t will be a bottleneck in some games, in Skyrim and BF3 you will notice FPS spikes and/or lower than 30fps gameplay in certain cases.

whatever but the 1090t is fine for gaming i all cases well not 4 6990s on crossfire but even a 2600k can't handle that

I'll quote myself here.

Lower than 30fps....

LOWER than THIRTY FPS

http://www.overclock.net/t/1184541/fixed-skyrim-issue-1090t-bottlenecking-2x-gtx-460s

This is a post from a user using the 1090t and 2 GTX 460s - Look at the GPU usage comparison at the bottom.

This is NOT okay.

Oh and a 2600k could handle it fine if it weren't limited by its 20 PCI-E 2.0 lanes.

a 3930k would be fine with it right now :)

No one is considering the cost of a high end amd mobo vs a high end intel with the same features.. U save a bit on the amd and amd3+ will be supported by the next amd cpus code name piledriver

Oh, now you want to reduce your statement to only include a $120 amd chip?

For gaming the dual core i3-2100 will beat any stock AMD processor.

running away already doesn't look good for defending your statements.

Lets look at overclocked cpus since thats what the OP is planning. http://www.tweaktown.com/reviews/4350/amd_fx_8150_bulldozer_gaming_performance_analysis/index5.html

aside from hawx 2 and farcry 2, thats a tie with Intel having a 500 mhz advantage, 5.2 ghz I7 vs 4.7ghz BD. not looking good for saying Intel >>>> AMD.

so farcry 2 won on the intel by quite a bit, and I am sure everyone will agree that if you check any and all farcry 2 benches, its all intel cpus >> all amd cpus ... ever stop and wonder why?

From the earliest stages of development, Intel engineers worked closely with Ubisoft Montreal to make sure the Dunia engine could bring the game world fully to life by being multi-threaded. The result is the kind of game the Intel® Core™2 Extreme was made for.

http://game-on.intel.com/eng/games/farcry2/default.aspx

wow .. so if Intel works on developing a game from the start, AMD suffers at the hands of Intel. Imagine that.

So what other games have Intel had their hands on (or should I say wallet). http://www.intel.com/pressroom/archive/releases/2007/20070914corp.htm

Ok, now intel owns an entire physics engine. Guess what AMD, your out of luck getting any use out of that. What does that include?

http://en.wikipedia.org/wiki/Havok_(software)
Oh, look there is starcraft II, Just cause 2, and Skyrim
obviously some games are going to use the havoc engine more than others, but they aren't hard to spot.

Wether the game choices by toms was an accident or not is anyone's guess. Looking at the remaining 3 titles, you have metro 2033, your I3 handily loses to 4 of amd's cpus, and the other 2 games, BF3 and Dirt 3 are a tie.

How about some resident evil 5, another look at Hawx 2, and Stalker. those aren't on the havoc engine list. whats that at the bottom twice?

Trying to find reviews that cover the I3 2100 are fairly few, mainly because its not considered a future proof cpu.

SKyrim is for the most part a single-thraded game, saying BF3 is the same is a complete load of crap. your link to the forum post showed skyrim jacking one cpu core to 99%, the next one was 30% the main issue ended up being a problem with Nvidia's drivers .. imagine that ..

Battlefield 3 is one game that absolutely loves multiple cores. see how the i5 takes a hit compared to the i7? imagine what the i3 does. wonder if its down there with the 980 or 560.
