I7 930? i7 860? 1055T? 1090T? Which is best for 3D workstation

I have to decide between 4 set-ups for my next workstation. The real problem is that I recently read Intel is going to be retiring its 1156 and 1366 sockets meaning that I have no upgrade path save from buying a new mobo. I'd really like one more CPU upgrade sometime in the future. Apparently AMD is going to to release its Bulldozer CPU's which won't need a new socket. I'm just wondering if the 1055T or 1090T will offer the same performance as the Intel i7's.

If I'm to believe this review they probably do:

BUDGET RANGE: About $1700 or thereabouts. (non-US tho) The cheaper the better of course. The parts I listed cost about as much as I'm willing to spend on that particular kind of part (CPU, mobo, ...)

APPROXIMATE PURCHASE DATE: Within next few days. No more waiting.

3D and HD graphics workstation. Rendering machine. Photoshop. Also simulations which are often single threaded.

PARTS NOT REQUIRED: Keyboard, mouse and screen.

PREFERRED WEBSITE(S) FOR PARTS: I’m stuck with a local builder. They have a pretty wide choice of parts so most of your suggestions are acceptable.


OVERCLOCKING: Yes, stability is most important but I will to hopefully 4GHZ. SLI: Unknown since I'm not sure where GPU computing is going. Probably.

MONITOR RESOLUTION: 1680 x 1050, probably second screen in near future.

Corsair TX650 Watt PSU

EVGA GTX 460 1024MB 675/3600 EE (External Exhaust)


Corsair 4096MB XMS3-1600 DDR3 2X2048MB CMX4GX3M2A1600C8 i5/i7
Intel Core i7 860 S1156 Box 2.8 GHz 1333 MHz Quadcore
Gigabyte P55A-UD6 S1156 DDR3 USB 3.0

Only advantage is 8GB RAM. Would only buy if proven upgrade path is available for CPU.


Intel Core i7 930 S1366 Box 2.8 GHz 1333 MHz
Corsair 6144MB XMS3-1600 DDR3 3X2048MB TR3X6G1600C9
Asus P6X58D Premium S1366

Only 6GB RAM but expandable to 12GB. Proven set-up. Would buy if 1366 wasn't to be retired.


Asus Crosshair IV Formula AM3
AMD PHENOM II X6 1055T 2.8GHZ BOX AM3 Black Edition
Corsair 4096MB XMS3-1600 DDR3 2X2048MB CMX4GX3M2A1600C8 i5/i7 (only for i5 or i7?)

Cheaper, 8GB RAM and a possible upgrade path. I'm considering the 1055T because it's apparently as fast as the 1090T when overclocked, but cheaper.

Disadvantage: NO SLI. (mobo overheating issues?)


Asus Crosshair IV Formula AM3
AMD PHENOM II X6 1090T 3.2GHZ BOX AM3 Black Edition
Corsair 4096MB XMS3-1600 DDR3 2X2048MB CMX4GX3M2A1600C8 i5/i7

About as expensive as the 1366 system. But with 8GB RAM and a possible upgrade.

Disadvantage: NO SLI. (mobo overheating issues?)

Any advice will be greatly appreciated!

More about 1055t 1090t workstation
  1. 3D workstation will gain much advantage on better and multiple proc, then I would recommend i7 930, if you can still afford it. i7 930 has 4 physical cores and 4 virtual cores, in total 8 cores.
    Second best choice would be X6 1055T if you have difficulties on the budget. 1090 is too expensive, and not worth it.
    i7 860 is also not worth it, I like i7 820, but I still prefer either i7 930 or 1055T.

    3D workstation will also gain benefit from RAM capacity, i7 can use 6GB effectively(3 channels), 6GB should be enough. That is another reason choosing i7 930.
    If you use X6 than get 8GB.

    the only problem with i7 930...the upgradability is definitely closed...not a chance on upgrading if you are going Intel.

    Recap (quick) :
    X6 1055T +8GB RAM (4 GB is also not a problem , but 8 is recommended by me) = Budget
    i7 930 + 6 GB RAM = Performance
  2. Yup!
    1090T is too expensive, just OC a 1055T...voila...you got yourself a 1090T.
    i7 930 deserves it's price, you can not get i7 930 by overclocking i5 750.
  3. This would be my purely CPU/Memory intensive config with either zero GPU acceleration gain and/or peeps awaiting some mainstream desktop GPUs to get official certification for the apps that *do* take advantage of GPU acceleration (and have a working rig still on IGP)

    List of apps

    Rendering and Render farm (with option of discrete GPU if net gains)
    Encoding (with option of adding video transcoding card if mission critical/time = $$)
    Video/Photo editing
    Engineering/Mathematical apps
