1090t vs i7 980x?

[snowdude1492]

I'm planning on getting 2 6990's in q1 2011... I also would water cool either proc. if i theoretically overclocked each to 4.6 ghz, would the 1090t still bottleneck?


I was also thinking since the 1090t is 33% of the price i could upgrade every core # update from amd 3 times and still be the same price as the i7 980x...

am i thinking about this correctly?

or should i just opt for the i7 980x... (or the 990x in q1)


Thanks so much in advance.

I doubt you could get a 4.6 OC on a 1090, but that is beside the point. What are you using your computer for that you need 6+ cores and 2 6990's?

I am assuming this is a gaming build, so unless you are doing to do something that can use more than 4 cores, spending $1000 to go from a 4Ghz Nehlem to a 4.6Ghz Nehlem does not seem like an effective upgrade.

Is your current 920 on water cooling and can you go higher than 4Ghz? If not, this is the upgrade path I would take.

Here is what I would recommended:

1) Buy 1 6990, see if it meets your needs.
2) If not, buy another 6990, see if it meets your needs.
3)Check for CPU/RAM bottlenecking.
4)Start to look at CPU upgrade, etc.

My friend wants to buy my build for 2k (with moniter etc) and I was going to give myself another 2k on top of that 2k for another KA build.

my plan was asus rampage III (if i7) or crosshair iv extreme (amd) 2400 mhz ddr3 8gb (i'm getting it for a large discount) the 6990's (if they are 600 usd like last time) and a 800d case and water cooling system that i wont get into because i don't feel like getting into all of that... my only question is...
will the 1090t bottleneck (if it is oc'd to its limit)... regardless of what my upgrade plan is.

Yes it will be bottlenecked, quite severely. My 1055T barely pulls the weight of my stock 5850. A 1090T is sufficient to pull the weight of a 5970, but no more.

My suggestion is to buy either a Bulldozer or Sandy Bridge with your 6990 crossfire, which comes out around the same time. If what i speculate of how fast the 6990 is, is remotely close. 1 6990 will be enough to max every known game with 60+ FPS.

No current processor will be able to carry the 6990 Crossfire.

Although 6990 is unreleased, I *think* 1090T would bottleneck in some CPU intensive games, at least at lower resolutions/single monitor. If this is a multi-monitor setup, you would probably be OK though.
I would not expect to be able to upgrade the CPU though, as AMD will prob just be putting out 100 MHz bumps of the same process and stepping until bulldozer comes out.

i'm planning on running a regular 1920x1200 or maybe a 2560x1600 single monitor set up

also I thought sandy bridge was to be a midrange proc... Am I wrong?

 

[cjl]

Sandy bridge will launch as a "midrange" processor, but the current indications are that the fastest "midrange" Sandy Bridge CPUs will actually be as good or better than the 980x for gaming.

^ +1. Also the performance/extreme Sandys will be out next summer and if more cores is the OP's goal, there will likely be a 10-core/20-thread monster available at a monster price , if the rumors are true..

 

[snowdude1492]

so when is the release date of these supposed beasts?
should I guy a p67 mobo and get a normal sandy bridge then upgrade later or just wait?

Well if I were in your place, I'd wait until Jan. 9th when the mainstream SB reviews should be out. I'd be surprised if at least some of those reviews didn't have details of the later SB releases, such as socket 2011 which is what it sounds like you really want.
