Chip Comparison: FX-8120 v Core i5

I'm looking to upgrade my core2 Duo E8400 to something more future-proof.

I'm currently running:
C2D E8400 @ 4GHz
4GB DDR2 800 @ 1081MHz
Geforce 9800GTX+
2x Seagate HDD (133MB/s)
P5Q Pro Turbo
Dual Samsung Monitors (4096x1152 resolution) :sol:

What do I use it for?:
-FL Studio Primarily now
-GP (Like browsing waterfox, watching videos,etc)
-Plenty of Audio/Video converting.
-Autodesk Inventor, Mathematica, Visual Studio
-Minecraft, UT3, Crysis, Portal 2.
-Overclocking

I don't do a lot of gaming, and even so, I figure I'll be more GPU-limited than anything. I'm mostly looking for more cores, more memory bandwidth, and better Hard disk performance.

So, here's what I'm considering:
-OCZ Agility 3 60GB ($50ish on newegg)
-A-DATA DDR3 1600 2x4GB
-Same Graphics card
-Asus Motherboard (I want versatility in fan controls, and I love the brand)

And I'm trying to keep this all in the $300-$400 range.

So here's where I'm tied down: I've been seeing the FX-8120 on newegg for about 170, with an ASUS mobo with all the features I want for $90-something. However, I'm also seeing Intel's Sandy-Bridge series for about $20 more, and I'd need to spend at least $100 for the boards that even support the RAM.

So basically, I'm torn between the two setups.

Do I go for the 8-core setup for the trimmed prices, or Would the extra money be worth it for the Intel offering? I'm in college, so every penny counts.

  1. That would be the i5.
  2. Either an I5 or I7 would fit what you're looking for.
  3. Okay, I did much more research after seeing your responses. Yes, i5 DOES sound awesome.

    Next question, though: Ivy Bridge or Sandy Bridge? I want the ddr3 1600 speeds available, but doesn't ivy run hotter due to bad TIM?
  4. Sandy and Ivy both support 1600mhz+ ram. I would vote sandy since you are overclocking.
  5. Yeah, I was thinking the same thing: Put in an extra 20 bucks and get the 2500k instead of the 3550.

    The ASUS Z68 motherboard I'm looking at seems to be a beast in overclocking, much like my current board.

    But I'm reading the specs about the 2500K, and I'm seeing only 1066/1333 speeds supported by the integrated memory controller. I suppose this doesn't matter if my multiplier is unlocked and thus I can boost the interface speed without sacrificing RAM stability.

    I just want to make sure I'm getting the most out of my hardware. 2500K is looking pretty good right now.
  6. Hold on a sec, I'm comparing benchmarks again.

    http://www.guru3d.com/article/amd-fx-8150--8120-6100-and-4100-performance-review/1

    Now, remember that the 2500K is currently $220 on newegg, it's the main competitor to the FX which has an unlocked multiplier. It would be placed in a $110 motherboard in order to get the fan controls, RAM support, and 2 PCI-E slots I want. $330 in total.

    The FX-8120, while it was a disappointment as an architecture, is only $170 on newegg with everything unlocked. And the motherboard will be $95 with both PCI-E slots, RAM support, and fan controls. A total of $265

    So, the performance seems similar either way, but there is now a $65 price delta, which is pretty significant in a budget tech update.

    And if the 8120 overclocks as well as they say, I should be able to notch it up past the Sandy Bridge proc.
  7. The FX 8 cores aren't faster until you reach 4.5ghz+ you can only surpass a stock clocked i5-2500k. But if you overclock the i5-2500k, to 4.5ghz which is VERY easy to do as the multiplier is unlocked, you would need a 6ghz FX 8 core to beat it!
  8. Okay, so here's where I stand as far as my purchase/sell options:

    Hopefully the doc is available.
  9. are those IDE hard drives you are going to re-use?
    :pfff:
  10. Do you live near a microcenter by chance? Their combo's are impossible to beat.

  11. I'm about 3 hours east of St Louis, so I suppose it's doable. Especially with some of the deals I'm seeing. Right on the first page, I see I can get a core i7 for the same price!

    To Looniam: I haven't used IDE in, heck, forever. I'm currently running two 160GB SATA drives that I got completely free. They're running in RAID-0 ATM. I was going to put the OS on the SSD and have the HDD's for extra room.

  13. lol. Didn't think about that. hah.

    So, I'm seeing a core i7 at a reasonable price at microcenter. About $220, same as I was willing to pay for the i5-2500k. However, it's ivy bridge and isn't a K model.
