    I'm looking to upgrade my system in the near future I have most of it mapped out, but I'm a little torn on the CPU. I have been looking at Intel's Bloomfield i7-950 and their Sandy Bridge i7-2600. I'm not sure if the SB is worth the $30 difference or if even going with the Sandy Bridge i5-2500k is more "bang for the buck" sitting at $230

    Future System:
    CPU: i7-950 Bloomfield
    Intel Core i7-950 Bloomfield 3.06GHz 4 x 256KB L2 ...

    Motherboard: Asus Sabertooth X58
    ASUS Sabertooth X58 LGA 1366 Intel X58 SATA 6Gb/s ...

    RAM: G.skill 6gb DDR 1600
    G.SKILL 6GB (3 x 2GB) 240-Pin DDR3 SDRAM DDR3 1600...

    Video Card: Nvidia GTX 560 Ti
    EVGA 01G-P3-1561-AR GeForce GTX 560 Ti FPB (Fermi)...

    Power Supply: CORSAIR CMPSU-750TX 750W
    CORSAIR CMPSU-750TX 750W ATX12V / EPS12V SLI Ready...

    Case: Cooler Master HAF 932
    COOLER MASTER HAF 932 RC-932-KKN1-GP Black Steel A...

    Obviously if I were to go with the Sandy Bridge the mother board and CPU would change in that list, but that is where I am at now.

    The sandy bridge line up is really great performance wise compared to that of Bloomfield. however you woudlnt be able to get a P67 motherboard as they have been recalled due to a flaw in its design.

    Yeah I read about that, something along the lines of a communication problem between the CPU and the Sata2 ports 2-5 on the board. But the boards are going to be back out on the market in a few weeks which is when I'll have the money anways haha.

    Ive read reports that it will be back out sometime this month and sometime next month (april) so id otn know which is true. I do however know that Intel has shipped the fixed sandy bridge to motherboard manufacturers.

    Ah ok awesome, well in the case of the Sandy Bridge processors, where do the i5-2500k and the i7-2600 stand compared to each other? Is the lack of hyper-threading in the i5 worth the $70 jump to the 2600 for only a slightly higher clock speed and L3 cache and the addition of hyper-threading?

    Im not sure what the numbers are compared between the two, but I do know that if the model has a "K" in it that its unlocked where as the non "K" are limited to how far you can overclock. Ill look around to see if I cant find comparisons of the two CPU's.

    EDIT: From what I have seen so far already, it would seem that the i5 might be the more ideal choice for gaming as the hyper threading woudltn serve much use as HT creates 2 threads per core basically giving a quad core 8 virtual cores. However if you do video processing or sound editing -things of that nature- then the i7 with HT would be more ideal compared to that of the i5. Otherwise the difference is minimal.

    The i5 version has a base clock speed of 3.3ghz and the i7 has a base speed of 3.4ghz and they are both advertised as having a 400mhz increase with "Turbo Boost."

    See my edit. The speed of that of the i5 and the i7 woudlnt be noticeable at all and if need be you could just OC the i5 to the speed that you want anyway and it wouldnt cost you an additional $70 for the i7 clock speeds. You do however lose the hyper-threading.

    Yeah I missed the edit haha, thank you for the advice the hyper threading was the main point of concern in the dispute, but since the machine is more focused towards gaming and I want a fairly cheap system the i5-2500k sounds like a good choice.

    If X58 based system - better choose i7 960 (should be around same price) if Sandy Bridge P67 - go for i7 2500K or 2600K (both are unlocked and unleashed) but then u should wait B3 revision of P67 (previous has some issues with Sata2 controller). So far about CPU. What about mobo? for x58 probably your Sabertooth will be enough good, but for P67 i would suggest MSI P67A-GD55 (B3) or MSI P67A-GD65 (B3). About GPU - same price (bit more) comes HD6950 2GB version which can be easily unlocked to HD6970 which is way faster then GTX560Ti. For PSU - never knows what future will bring - so pay 45$ more and get HX850 or OCZ ZX850 :pimp:

    The P67 motherboards have been re-released with the "B3" modification made to the chipset on the boards fixing the Sata port issue. A few are back up on newegg all ready.
