Upgrading CPU, But to What?

Hi Guys !

Im currently running on a BFG 680i SLI Motherboard and want to upgrade my processor from an E6750 2.66GHz (333 x 8).

As this is a 680i board supporting 1333FSB, it supports only Core 2 Duo 65nm (Conroe), Core 2 Duo 45nm (Wolfdale) and Core 2 Quad 65nm (Kentsfield).

From looking around I would assume my options are:

E6850 (3.0GHz, 4mb Cache, Dual Core, 1333FSB (333FSB x 9 Multiplyer)) (Conroe) - £145.00 - Ebuyer

E8400 (3.00GHz, 6mb Cache, Dual Core, 1333FSB (333FSB x 9 Multiplyer)) (Wolfdale) - 120.00 - Ebuyer
E8500 (3.16GHz, 6mb Cache, Dual Core, 1333FSB (333FSB x 9.5 Multiplyer)) (Wolfdale) - £142.00 - Ebuyer
E8600 (3.33GHz, 6mb Cache, Dual Core, 1333FSB (333FSB x 10 Multiplyer)) (Wolfdale) - £202.00 - Scan

Q6600 (2.40GHz, 8mb Cache, Quad Core, 1066FSB (266FSB x 9 Multiplyer)) (Kentsfield) - Discontinued?
Q6700 (2.66GHz, 8mb Cache, Quad Core, 1066FSB (266FSB x 10 Multiplyer)) (Kentsfield) - Discontinued?

QX6700 (2.66GHz, 8mb Cache, Quad Core, 1066FSB (266FSB x 10 Unlocked Multiplyer)) (Kentsfield) - £250.00 Ebay - New
QX6800 (2.93GHz, 8mb Cache, Quad Core, 1066FSB (266FSB x 11 Unlocked Multiplyer)) (Kentsfield) - £213.00 Ebay - Used
QX6850 (3.00Ghz, 8mb Cache, Quad Core, 1333FSB (333FSB x 9 Unlocked Multiplyer)) (Kentsfield) - £330.00 Ebay - New

It would appear that my options are ... well limited.

The E8400 is the same as the E6850, but with more Cache a lower die size and £25 cheeper.
The E8600 is just silly prices compared to the E8500
Q6600 and Q6700, well if I can't buy them, they won't run very fast.
QX6700 and QX6850 are silly prices for a last gen CPU (for this cost I might as well, start the upgrade to i7-920).
QX6800 I can't find new (or atleast from a reseller I have an account with), I don't think I will ever buy a CPU 2nd hand.

Are thier any options I have missed out?

Something I have not considered?

Because at the moment I would look like the E8500 is a chip that is not only good value per performance but will overclock to silly speeds.

More about upgrading what
  1. what di u want to do with ur comp?
  2. I do alot of gaming in 5040*1050 res,

    upgrading to I7-920 is not an option, I'd be looking at £200 for m/b, £220 for CPU and £130 for Ram.
  3. Well, I wouldn't even look at any of those dual cores if you want to upgrade because all you are buying is clock speed, just overclock it if you want a higher clock speed. Depends on what you are using it for if you need a quad core or not.
  4. RAM DDR3 1333 4 gigs

    If u want to change mobos it is a good time to switch to AMD cuz LGA 775 will be dead in a year or two

    this is good

    and a 955 BE then Overclock it

    this will give u similar FPS to a 920 for less
  5. the m/b would need to support 3way SLi, do AMD offer such things?
  6. Full PC Spec,

    Intel E6850 2.66GHz CPU (Overclocked on Air to 3.2GHz (Standard Intel HSF))
    BFG 680i SLI Motherboard,
    4Gb (4x1) Crucial DDR2 800mhz 5-5-5-21 timings
    Coolermaster 1100 UCP PSU
    Antec P193 Case
    3x Asus GTX260 216 (Overclocked to 715/576 Core - 1115/1015 Memory - 1415/1242 Shader)
    Matrox Triple Head2Go Digital
    3x Dell 2207 WFP Monitors 3(1680 * 1050)
  7. If I were you, I'd roll out all of the other Dual Cores since it won't be much of an upgrade.
  8. E8500 will nicly OC tho, (4.5ghz +).

    Im assuming I am CPU bound on most games, will the extra throughput not be noticible?
  9. Well same. I am playing games a lot and Quad cores managed to catch my eyes better. Personally I've stopped on Q8400 but the quad ones you've chosen are good aswell.
  10. The reason I didn't list any of the Q8xxx or Q9xxx is because they are 45nm Yorkfield cores that my 680i SLI board can NOT support.
  11. http://www.newegg.com/Product/Product.aspx?Item=N82E16813130236

    here is a three way SLI offering

    put that with some ddr3 1600 mhz RAM, 955 BE, and ur GTX260 and u will be able to play amazing quality on games
  12. If I was going to upgrade, I would stick with Intel, sorry. Though thanks for taking the time to look up the m/b
  13. why? AMD is just as good for less....maybe a couple FPS lower but nothing that makes a differenc and u would not see it at all
