Sandybridge advice for 2560x1600 Graphics

post #1 of 2
Thread Starter 
I am getting to the point of information overload, so I thought I would come and ask for your advice.

I am trying to build a system for a 30" monitor I will be getting soon as a gift. (I am to provide suggestions, but something similar to HP ZR30w 30"[http://www.newegg.com/Product/Produc...2E16824176177])

So far I have(from my old computer or already ordered):
GFX Asus EAH5850 TOP

Cooling: Coolermaster Hyper 212+

RAM: Ripjaws (2x4GB) DDR3 1600 9-9-9-24-2N

SpeakersInfinity TSS-800 5.1 speakers
(Do I need something besides an audio card to get them to work for a computer? They keep mentioning receivers but that is for home theater systems right?)

OS Windows 7 64 bit Ultimate

I have a soft cap of about $1400 to work with beyond this
I am planning to get:
GFX $185 - Asus EAH5850 TOP (I am somewhat worried that 1GB might not be enough for 2560x1600 though, and some of the reviews on Tom's Hardware couldn't get 8xAA to work on Crossfired 5870s at these resolutions)

CPU $193 - Sandybridge i5-2500K (I am very happy with what the i5 can do for $200)


Motherboard ~180 - I was planning to stop by a Micro Center to get Asus P8P67 Pro and the CPU for their $120 off combo deal, but my location ran out of the motherboards.

Now I am torn between Gigabyte's GA-P67A-UD4 [http://www.newegg.com/Product/Produc...2E16813128463] and getting just the CPU from Micro Center for $193.
OR
This NewEgg deal for MSI's P67A-GD65 bundle [http://www.newegg.com/Product/ComboD...=Combo.576625]
AsRock P67 Extreme4 (I liked that the top PCI-E x1 could fit a sound card without being interfered with by the Crossfire setup) or Biostar TP67XE as the other 2 boards I was looking at.

PSU ~$120 - I checked on Hardware secrets and [http://www.newegg.com/Product/Produc...2E16817207001] got a good review.
I also saw [http://www.newegg.com/Product/Produc...2E16817116010] get recommended, if 650W can keep 2x5850s in the 40%-60% optimal load range.

Case $115 - Azza Hurican 2000 [http://www.newegg.com/Product/Produc...2E16811517010]
I will also need a 200 mm bottom of the case fan and a second 120mm for the 212+ push pull setup. (How do I avoid CPU cooler fans being mismatched?)
And probably a fan controller, no?

Storage $130 - I was thinking 2X1TB Spinpoint F3's in RAID 0 [http://www.newegg.com/Product/Produc...185-_-Product]

Mouse $50 - R.A.T. 5 gaming mouse (Anyone have it? Worth it or overpriced?)

Laser Disk $50 - Cheap Blueray drive/ DVD burner [http://www.newegg.com/Product/Produc...2E16827106325]

Thermal Compound ~$6 - ARCTIC COOLING MX-2 Thermal Compound (Friend chipping in half of the price, so he can use it when he builds his Bulldozer rig.)

Sub Total : $1029

Remaining questions:
SSDs I would really like to get 120GB somehow, but am totally lost for best setup. (Does TRIM always get disabled if you use RAID 0?)

Sound card / other needed equipment (Haven't started looking yet)

Keyboard?

I think I will allow myself to succumb to sleep, and buy stuff tomorrow when I am thinking clearly.

Thank you all in advance!

I would have thought dual 5850's should be sufficient for most games at 2560x1600 res, I cant see you breaking any fps records but you should be able to play most things at 25+fps...if you're worried about it you could consider adding a 5870 or even 5970 to your 5850 for extra power (i'm not sure if you would be able to Xfire a 6xxx with your 5850, but if you can it might be worth looking into)...theres some info and benchmarks in this article that you might find helpful http://www.tomshardware.com/reviews/...5850,2433.html

With regards to the motherboard, I've read some really great things about the gigabyte P67 UD4, the overclocking results and stability seem to be great with this board and the bios is as simple to use as all gigabyte boards...this is the board im leaning towards for my upcoming sandybridge upgrade.

As for power supply the XFX PSU's are a solid choice, though I think I would probably go for a 750W model just for the added headroom and security with Dual 5850's using about 450-500W of power at load. The Corsair HX 750W would also be a great choice.

For your SSD question, you do lose TRIM support if you have a RAID0 setup which can have it's disadvantages, have you considered getting 1 x 128gb Corsair C300 SSD to make use of the on board sata 6gb/s?
