PLEASE HELP CHOOSE A MOBO FOR MY BUILD!!

Hello everybody, I am building a new system, and trying to decide what is the best mobo for my build?

EVGA 280 GTX 1GB

I NEED A BOARD THAT WOULD BE ABLE TO ACCOMODATE ABOVE MENTIONED, BE EASY OVERCLOCKABLE, AND PRETTY RELIABLE. I WAS THINKING ABOUT ASUS PQ5 BOARDS, IS IT A GOOD CHOICE? WHAT IS THE DIFFERENCE IN THE MODEL OF THE BOARD SUCH AS DELUXE/ PREMIUM/ PRO/ WS/-E/

ALSO WHAT DO YOU GUYS THINK ABOUT THIS ONE?

ANY THOUGHTS ON THIS WOULD BE REALLY APRECIATED

Actually I like the 680i boards or the p35 boards.....if that is in your budget range....as for overclocking....everything matters....cpu...board...memory.....certain boards clock better or worse depending on setup and memory selection

As for the one you have posted, it is far from being a terrible component, but it wouldn't deliver the sort of performance you will want out of a gaming system. Overclocking on cheap boards is usually sluggish at best, that one has no SLI compatability, so you're stuck spending $400 on a new card in a few years instead of just using SLI to add another GTX 280, which by then will be much cheaper. You really do get what you pay for with budget boards. If you were trying to build the ultimate $500 gaming rig, then that one would be great, but your video card costs nearly that much, and you shouldn't let that get spoiled by cheap boards. Believe me, you'll want to just bite the bullet and spend a good $150+ on a descent SLI mobo.

But rampage is better for ati, if i am not mistaken. I am thinking about the 780I http://www.newegg.com/Product/Prod [...] 6813141005, though reliability rating on it is not the best. What do you guys think about this one

do they differ a lot? I am thinking since my gpu is going to be EVGA maybe the mobo should be EVGA as well? What are your thoughts on 9800gx2 and 280 gtx both 1 gb, is 280gtx the best one out yet? I didnt want to spend more than $200 for mobo. Is there anything decent up to $200?
I thank you all for taking time to reply to me!!!

either get a biostar P45 or an evga 750i SLI FTW mobo

and +1 to "I THINK YOU SHOULD STOP SHOUTING! "

Originally i was goiing to go with this one it is pretty reliable people say.

It is overclockable as well, but I am debating whether to go sli or no.

i dotn know about your card, but sometimes higher numbers dont always add up to better performance.. some argue that some cards with large memories (like your 1gb card) dont even utilize all of the memory

simply put, sometimes, its a marketing scheme to get you to buy their "upgraded / more memory" cards

on that note, there are plenty of benchmarks out there ....
some single cards kills crossfire/sli setups
some crossfire/sli setups kills singl card setups

in my opinion, you should go crossfire with a x38/x48 board like gigabyte's GA-x48-dq6

and to answer your question, vaguely, i dont think there will be a huge difference for you to notice unless you use maximum resolutions (like upwards of 1900 x XXXX)

just search in the forums about crossfire/sli vs single card gpus... there are many posts and articles about them.... look at the benchmarks and you'll see

Thanks guys, the only thing i have a 40 inch LCD Monitor/tv so I am probably going to play with resolution of 1900 X **** I bought a samsung ln40a650 for $1400 not its time to build a gaming rig.

It probably should do the trick. My goal is to build a good gaming system that will be able to play all games on high and not to spend a fortune. Besides If i get 2 8800 gts i will also need around 100w psu which is around $200. At the end I will get more bang for a buck if I get a single videocard. Right now i have pentium 4 4ghz 2gb ddr400 membory 550w powersupply, 256 mb 6800 ultra and abit ai7 mobo. All of that just doesnt do the trick anymore. Plays Crysis but on low settings. So I am already certain that I am going with 1 videcard will wait 2 more weeks to see what 4870x2 is than if it is not much better will stick with 280 gtx. Mushkin ddr2 800 ram ocz 700w psu q6600 640gb wd harddrive and a blue ray burner maybe. As of now i am choosing between:

the only thing that bothers about 780i, is that people complain that the voltage is not stable on the cpu when overclocking.

I know its a bit overpriced, but gtx280 is 1 gb and 4870 is 512mb
