Need help choosing a new build

[eddietandy]

I think I may be suffering paralysis of analysis, trying to decide the last few pieces for my new build. Time to ask the audience I suppose. I'm down to CPU/MOBO/RAM and a cooler.

I've spec'd out AMD and Intel, which is more or less $500 either way:

Option 1: Intel i7-870, Asus P55D-E LX, G.skills 8 GB (2 x 4GB)
Option 2: AMD PhII X6 1090T, GIGABYTE GA-890FXA-UD5, G.skills 8 GB

I go round and round swapping out mobo options, but generally that's where I sit. Also considering the i5-760.

And then there was option 3, which surprisingly is around $600:
Intel i7-950, Asus Sabertooth X58, G.skills 12 GB (3 x 4GB).


This will be a home PC for development/lab/programming, some VM, some gaming at 1920x1080. I just want it to be a bad mutha for the money and be a happy camper at the end of the day. (Also, I've looked at Sandy Bridge, but I just don't know any real prices. If I knew I could get into a 2500k/2600k for the same money I'd probably wait a few days). I'd really appreciate some help pushing this build over the finish line.

Here's what I already have purchased:

Case: Lian Li PC-K62
GPU: Asus EAH5850 Directcu 1GB
PSU: XFX 750 Black edition
Display: Asus VH242H
HDD : 1 WD Caviar Black 1TB, 2 Samsung F3 1TB
DVD : Asus 24B1ST DVD burner

Skip the i7-870 and get the Sandy Bridge i5-2500K.

If you have a Micro Center near you, that one should be about $179 on opening day.

If you have a 64 bit OS, get at least 4 Gb of RAM, DDR3-1333, and you should be ready to rock & roll.
Personally, with your list of applications, I'd go with 8 GB of RAM, but that's me...I got 8 for my home rig...and my uses aren't nearly as demanding as yours.

If your applications take advantage of hyperthreading...go with the i7-2600K

Hey, thanks for the quick reply!

Unfortunately, no Micro Center anywhere nearby. The i7-870 had some appeal for the hyperthreading, but as I understand it the SB equivalent (if there is such a thing ) is the 2600k. That is probably going to be more than I want to spend. Generally trying to stay around $1500 or below, total (including monitor).

Maybe the hyperthreading isn't that big a deal. I'm honestly more interested in real world performance than a paper tiger anyway. Hopefully the 2500k will be in line with the price of my current options.

It looks like the 2600K should be priced at $317...the 2500K at $216. Both are pretty good prices, and are about the same as the current "equivalents," the i5-760 and the i7-875.
Both bring a nice bit of performance increase over the current models.

Whether you NEED hyper-threading or not all depends on the applications you run...very few games take advantage of HT...while many graphics applications and such use the extra boost of the multiple threads.

I agree with Boomer. You want option 4: Sandy Bridge.

Even if it turns out that the 2600K is too expensive for you, you still want to get Sandy. The 870 does beat the 2500K in a few tests, but not by a large margin. Where the 2500K wins, it usually wins by quite a bit.

bing! YUP!

I'm going to wait (like nearly everyone else) on Sandy Bridge, after reading some of the reviews, and of course, wise counsel here. :thumbsup:

The 2600k sounds like what I'll want, so if it truly hits the Egg at around ~$300+, I'm in for it. Now to spend some time reading up on the P67 motherboards.

I did pull the trigger on the latest RAM special at NewEgg today. $95 for G.Skill 8GB @1333, CAS 7, 1.5V. Based on what I understand, that will be just fine for SB. Does that sound right?

Thanks for the help guys.

Yeah that RAM will work fine. Hopefully SB won't be priced gouged like the 58xx was.
