New Gaming System, based on reading here

I am looking to build a pretty decent gaming rig, I do like all the eye candy turned on. Will be purchasing dual 24" monitors to run things. Though both monitors will not be consistently hooked up the same machine all the time. I need to know if this will satisfy the dual monitor setup.

Other things that I missed let me know. I do like the K1 nic card, as I have a friend that had one and really made things go smoother for online play. I tend to almost all online gaming now so a smoother connection is always helpful. Currently this is the top of the budget for what I want to spend on a rig. I hope that you guys can help make sure that what I have is good enough to last awhile. I know that I can upgrade to a second video card early next year, as that is the plan.

All of my homebuilt systems in the past have been AMD based so this would be the first intel chip setup.

as it looks like your not cutting any corners, maybe jump up to a 4870x2

that should let you crank up all the eye candy on 2x 24" monitors. just one would power both, but I'm not sure of what level of performance you are desiring out of 2.

If I'm not mistaken the P45 does x16 and x8 for crossfire.

I am keeping a big power supply for longevity sake. I would rather buy a over kill one now and not have to worry about it for awhile. Besides in the past I have run into the issue of not having enough power.

I did take the suggestion for the motherboard and did decide on the gigabyte x48 ds5.

I also changed the ram to:
CORSAIR DOMINATOR 4GB (2 x 2GB) 240-Pin DDR2 SDRAM DDR2 1066 (PC2 8500)

I have always used Corsair without any problems so I think I will stick with something I know about.

As for going up to the 4870x2 that is a might big for my budget. I am currently hovering at $100 over what I wanted to spend.

No arguements about getting a great power supply from me, but you might want to look into this 850w signature Antec.

Review from Jonnygurus site.
http://www.jonnyguru.com/modules.p [...] y&reid=101

and 2 quotes from Oklahomawolf that tests the PSUs

"You may recall that the SG-850 received the first 10 out of 10 rating I've ever given out for performance, and I have a confession to make: after that product's very impressive showing, I installed it into my main computer where it is now running as I type this, displacing a very impressive in its own right 1200W unit. Not just any unit can make that claim"

"shows what can happen when you throw wads of cash at a renowned OEM known for server grade units and say, "Here, go nuts." "

The PSU will only deliver as much power as the computer components need. Getting a bigger one just gives you more room to grow. A high wattage PSU doesn't use more power.

WRONG!

look at a PSU's efficiency curve, it has a peak. that means the further away from the peak you are, the less efficient it is operating.

if you mean to say a 1000watt PSU doesn't alway draw 1000watts, that is correct.

but the main factor here is initial purchace price. why waste $100, when that money could be used to give better performance instead of just the potential to jumpstart your car in a pinch.

memory is memory to a point. I just shop by specs, not so much by brand.

I'm buying a computer soon too and I'm comparing your build to mine.

This case will save you some money and has higher rating I think

This powersupply has more watts and is cheaper and has more reviews, if you were still using the other one.

Ruffels,

On the subject of the PSU, I fully understand your desire to have a higher watttage unit.

You could do better however. The Antec Signature 850W is the finest PSU you can buy in the US. It's more efficient, and is fully tested by people that know how, not people with voltmeters and a website:

If you take the time to read that review, I'm sure you'll change your mind.

As stated, a Corsair 750TX is likely all the PSU you'll be needing, but it's your money, and if you want the best you should get it.

There is no guarantee that that Cooler Master is actually better than a Corsair 750TX anyway. It hasn't been tested right yet.
