Sand Bridge i5 build comments/segguestions please
GPU: x2 MSI 6870
http://www.newegg.com/Product/Produc...82E16814127560

CPU: i5 2500k
http://www.newegg.com/Product/Produc...82E16819115072

Mobo: ASUS Maximus IV Gene-Z LGA micro atx
http://www.newegg.com/Product/Produc...82E16813131759

PSU: Antec High Current Gamer Series HCG-750
http://www.newegg.com/Product/Produc...82E16817371049


Ram: CORSAIR Vengeance 8GB (2 x 4GB)
http://www.newegg.com/Product/Produc...82E16820233144

Any suggestions or comments are welcome. I'm basically looking at upgrading to a new gaming rig that can support either crossfire/Sli support for future upgrading. Also plan on doing some OC to the Cpu and GPU's. Cooling and other peripherals are already taken care of thanks!

All your links are broken. But why not go full ATX? Running two GPUs on that board is going to give them no "breathing" room so they are going to run a good bit hotter. Also you have no other expansion slots to add a sound card or whatever else you might want in the future. Lastly 900W is way overkill for two 6870s.

Depending on what cooling you're using, Corsair Vengeance might not be your best choice. If I recall correctly, I think they have clearance issues with some heatsinks.

Maybe go with a 6970 or 6950 then later on CF with another?

Fixed the links, my choice in motherboard has some features I like nice built in X-fi card not as good as aftermarket but still good. The packet prioritize and the Intel Lan. Its got 2 Pcix16 slots which is all I will ever use. I changed the power supply to the 750 one didn't think 900w was overkill. As for the gpus the performance gains from the 6870's to a 6970 or 6950's aren't enough for me to wage out extra cash. So gonna go with these until they need replacing. As for the airflow problem, if they get to hot to my liking I'll be getting a water block for them and running their own gpu loop.

Performance gain from 6970 / 6950 2gb will give you a huge gain, but either way even if you crossfire 6970s all you need is 650 watt power supply.

I am using the HCG 620 watts with my CF 6870s

http://www.newegg.com/Product/Produc...82E16817371048

if you going spend money to get 750 watts, might as well pay a little more to get 850 watts so you can CF/SLI anything you want (excluding 590/6990 of course)

Those are good 6870s but unless you plan to OC dramatically your video cards, just look into the reference types for 30-40 buxs less. AMD Overdrive program already auto OC the reference cards to 920/1120. This MSI is 930/1050 so is it warrant to pay the premium for 'factory' OC, when all reference cards can do 920/1120 easily from the AMD Overdrive program?

I would just get either one of these:

http://www.newegg.com/Product/Produc...82E16814102948

http://www.newegg.com/Product/Produc...82E16814150506

Also get a regular ATX board. I can tell you right now ... the micro ATX your 6870s going run HOT. They are running quite hot with my regular ATX already. You will want to have at least 1 slot space between the two cards.

I would say go NVIDIA so you don't have to deal with crossfire driver issues? I think he was saying from what youre spending on two gpus why not just buy the best one you can now and then crossfire when they come down in price/you need the power.
