Phenom II X4 965 vs. Core i7-950

Building a new computer (my first build) and trying to decide on a processor and, following that, a motherboard. I'm looking for the final product to be a strong all around machine: I tend to run around 3-4 apps at once: Browser, OneNote, iTunes, and often another Office product. I would also like to be able to use the machine as a remote desktop server for my laptop and possibly as a media server. That's the easy stuff.

The more processor-heavy stuff is as follows:
Solid Works (CAD), I don't need a workstation but I need something that can run basic CAD without the excruciating delay I have when I use it on my laptop;
Moderate data analysis: 30,000 or so data points in excel and non-linear model fitting in Matlab and Mathematica;
I also expect to be doing some fairly intense coding with modifying a Linux distro to make a new custom OS.

Just to be through, I will likely be using 64-bit Ubuntu as a primary OS and dual-booting to Win7 when I get the money to buy yet another copy.

Right now I'm deciding between the AMD Phenom II X4 965 3.4 GHz ($160) and the Intel Core i7-950 3.06 GHz ($230) and I'm stuck.

Thoughts?

It's better not to choose between two CPUs but between two complete rigs. I say go to the Homebuilt Systems section and fill this sticky:

For now I can say you will probably have to choose between the i7 and the Phenom II X6 1055T.

Agreed, look at the build cost of the entire system, not just the CPU. An i7-based system will be more powerful but also more expensive, so your decision will ultimately come down to needs vs budget.

u talked about games earlier. so just because i7 will run a game on 120fps and a x4 at "barely" 50 fps, i7 is better.....srsly, ur paying more for performance u cant see...in other words, meaningless performance.

@OP: have u checked the i5 760. performance is very much similar to i7 750, but price is about 200

There are a few things to keep in mind. One is that the motherboard for the i7 will also be more expensive than the AM3 motherboard for the Phenom II. As far as upgrades are concerned, they're both essentially the same because the i7-980X is also LGA 1366 and it's light-years ahead of the i7-950. On the other hand, the AM3 socket will support the top-end Phenom II X6's so I'd call that a draw. Keep in mind that for maximum performance, you'll need to have RAM in multiples of 3 on the Intel board but only multiples of 2 on the AMD board.

As far as running the programs you want them to run, they'll both do it just fine. I'd save myself the $300-$400 difference on the full system cost and get the Phenom II X4 965.

@ Sarwar_r87: Thank you for the price.value suggestion. As it turns out, I have the good fortune to live very near a Microcenter, where they have the i7 930 for $200, which Newegg simply can't compete with.

To everyone else, thank you very much for all of your replies. Because the work I'm doing, besides just day-to-day computing, will be data analysis oriented (my current project is finding a statistically robust methodology for data analysis on muon lifetime measurement using a simple scintillator: lots of Matlab, and lots of excel and Mathematica) and CAD oriented I decided to go with the i7 (the benchmarks really speak for themselves).

My final build (which I am using to post this very moment) is:

CPU: i7 930 (I'll eventually do a mild overclock to ~3.5 GHz once a can afford a better cooler)
MB: Gigabyte GA-X58A-UD3R
GPU: (cheapest thing I could find till I upgrade to a Quadro) Geforce 8400 GS ($15 after rebate!)
RAM: 6 GB 1333 OCZ kit
PSU: 700 Watt ModXstream Pro from OCZ

Ended up spending just under $650 after tax, rebates, and optical drive, and case.

Thanks again all
