Mobo and RAM for i7-2600K build

Current build intentions (goals: heavy gaming, sometimes fairly heavy multitasking, hi-def video playback, etc.):

CPU: i7-2600K
GPU: Radeon HD 6870 (CF could be a possibility in a year or so, but probably not)

What do you recommend in the mobo and memory departments? (Prices are flexible, but preferably less than maybe $300 for mobo and $150 for RAM, unless there are good reasons otherwise).

On the subject of memory, when I was going to buy an i7-950, I was going to use this G.SKILL 6GB DDR3 1333 memory. (Triple channel, whereas SB only supports dual channel.)

Will this still do for the LGA 1155 boards? Is there a good reason to change to something else, some kind of Corsair Dominator or G.SKILL Ripjaws, etc.?

  1. No. Get dual channel ram. socket 1155 and 1156 can use tripple channel ram, but then you'll have a leftover stick. Get a 2 or 4 stick kit so you don't have leftover ram. 1366 and 1155 boards use different chipsets on the motherboard. 1366 is tripple channel; 1155 is dual channel. That's why they have a different number of ram slots.
  2. Budget ?

    MoBo - If budget not an issue, then I'd get the Asus WS Revolution as it's the only board I have seen so far with an NF200 chip that allows for full x16 x16 PCI-E lanes. Newegg can't seem to keep them in stock.

    Many will argue that it's only a few (2 - 5) % fps difference but for the $30 more over the Deluxe on a $2K build, ya talking a 1.5% in cost so it sounds like a more than fair trade off . And that 2-5 % comes from tests done over a year ago .... before the new more powerful GFX cards were released.

    I'm seeing a lot of builds also based on the Asus P8P67 Pro, Sabertooth and P8P67 Deluxe .... suggest you use the "compare" function on newegg to narrow down ya choices. The pro comes with some nice combo discounts on newegg w/ the 2600k

    If ya sure ya never gonna go to 16 GB, it's hard to beat the price on these Corsairs at $40 per pair.....$80 for 8 Gigs

    the 6870 and 570 are very well matched as single cards (6870 edged 570 by 526 to 524 fps), closer than any two cards from these camps that I can remember .... but in dual card setup, Guru3D gives the edge to the 570's which scaled 167 % to the 68xx's 157% in their tests

    Total FPS single card / SLI Xfire

    570 - 524/873
    580 - 616/953
    6950 - 479/751
    6970 - 526/825
  3. ^+1 It will work more than likely, but you'll have an unmatchable stick + break the Dual Channel.

    Q - What MOBO?
    Q - Why SLI?
    Q - What Resolution {monitors}?

    DRAFT - Suggestions. If you were looking at the 5970/5870 I'd try talking you to go reconsider X58.

    No it doesn't, it runs:
    x8/x8/x8/x8 {CF Only}

    Either Blue slot is x16, but if you use them both then you get x8/x8 {2 x PCIe 2.0 x16 (@ x16 or x8)}; I hate when they use this confusing play of words. BTW - the P67 + nVidia as of today is buggy -> BSOD. I assume this will be corrected soon.
  5. For mobo, preferably less than, let's say, $250, unless there's a good reason for it. That's flexible, but I'd rather not pay, say, $320.

    For RAM, I'd rather not spend $150 or something something unless there's good reason, in which case I'm more flexible. I don't see ever having more than 8GB probably, more likely 6 -- any reason to get 8 over 6, aside from them sometimes appearing in attractive 4GB price deals like the one mentioned?

    The Radeon 5870 isn't a bad idea actually, since it's comparable to the 6870... will do research comparing the two. However, i7-2600K is pretty firm, ruling out X58.

    SLI is possible, but I'd prefer just getting one good video card and sticking with it.

    Haven't bought monitor yet, but going for resolutions as high as I can get it... so 1920x1080 whenever possible, maybe higher sometimes.
  6. One of my friends @tecmo34 has a great post here ->

    Keep in mind the P67 is great for any single GPU and HD+ monitor, it's meant for the mainstream user and gamer. The SB CPUs are fantastic, but their chassis are by design limited - even those with add-on PCIe chipsets. The CF GPUs you listed are mid-level+ and so I'm not concerned too much about saturation loss, but the chipset itself has proven to create some form of bottlenecking at high resolutions.

    If you are looking at a single HD monitor then I'd stick with the SB build, it will perform superior to most X58s. Also, a single HD 5870 is fine with SB, CF HD 5870 then I'd lean towards X58. At ~cost of the HD 5870 you are getting into the range of the GTX 570. The GTX 570 is in most cases {depends on game/App} superior to the HD 5870, and in SLI it's no contest; nVidia for now scales better.

    8GB of RAM is a good starting point for rendering, but won't help much beyond that for anything else. The CAS 8 1600 MHz will only help in multi-hour rendering jobs, and maybe add 2~4+ FPS in gaming. Use the $50 towards an SSD.
