CASE!!!
Antec 900 or Antec 1200???

This is what I have decided so far. I know that megahalem heatsink will fit in antec900 but barely. Knowing that I am going to OC later down the road and also SLI my system should I just go with 1200? I just wanted to know others input.

Also any other comments on components/build suggestions are welcome. Thanks in advance

Coolermaster Scout if you are looking at portability of the system, but overall the 1200 will give better future options.

@eylee86, I feel you are skimpping on the graphics card...For that resolution, GTX260 would have a tough time pushing that many pixels...

And there are a few parts, that you can skimp on without loosing performance(RAM, Mobo) and investing the cash saved there to parts that matter the most(Graphics card)...

Here are a few suggestions that you can consider...

1. Get the D0 stepping of the i7...It would overclock better than the C0 stepping...

2. Get this mobo...
ASUS Rampage Gene...
Reason - Check this review of this board and you can see that it has more than suffice features for a very good setup...

3. RAM - The Dominators are one of the best no doubt but unless you plan on extreme overclock, their performance can be matched with cheaper RAM modules...
So if you plan for say a 4GHz overclock, then keep the Dominators or change the RAM to any of these...

4. For that resolution of yours, the GTX 260 is weak...And for a 30" monitor, 2x GTX 275 would be more suitable than 2x GTX260...
Either the GTX275 or if possible the GTX285...

thanks for the great input! I really appreciate it

gkay09,

I took your advice and am considering buying GTX275. How about HD4890? do you think GTX275 will do better than 4890?

Also about the processor, unfortunately, I already bought it through my relative, who got the i7 920 for $150. So I have no clue which stepping it is. It's a luck of a draw right? I hope i get D0 then.

Also I don't know if I can go with ASUS Rampage GENE because I was considering to upgrade a soundcard to EMU-0404 and if I SLI i won't be able to use the PCI slot do i?

thanks

thanks for the input caggles. Another reason I wanted to have 1200 was to have some clearance between the GPU units and HDD cage. Also I have a prolimatech megahalem waiting to be put in. I know that Antec900 fits the heatsink but just barely from what I've seen from forums. I also wanted some clearance for that as well. Well Antec 902 is definitely a tempting and good choice but just for $20 more I wanted to get more space to work with
