Hello,
I'm planning on building an i7 system and came up with the following config.:

CPU: i7 920
cpu cooler: intel stock cooler
case: haf 922
GPU: saphire 5850
psu: corsair 850tx
dvd rewriter: have plenty at home
mobo: GA ex58 UD3R

I'm not sure which ram or hard drive I should take and that's why I'm asking for help. I just want a small(250gb) fast hard drive. And for ram I don't know I was thinking 6bg ddr3 but I have no idea which kind. I am already over my budget so cheap solutions are welcome. And comments or sugestions for the other components are also welcome. thank you.

the samsung f3 drives are good the 250gb is $45 but rather get the 500gb for $54 if you cant find that the seagate 500gb is the same price

as for ram g.skill has some good value ideally you would want 1600mhz cas 7 ram cas 8 aint bad but stay away from cas 9 unless you just want and htpc ,1333 mhz ram will do fine also in cas 7 i wouldn reccomend cas 8 1333 ram but it should be ok

make sure you get LOW VOLTAGE ram 1.65v or lower anything over that will hurt your cpu

Thank you for the help and do you think my mobo could handle hd5850's in crossfire?

If you are over budget I will offer a couple suggestions. Since you are only running one video card I'd recommend dropping down to a 650TX since that will be plenty to power it (should save $30~). You could also do very well with an i5-750 cpu which will save you another $80~ or so, more than enough for a single GPU setup. Would also allow for a cheaper p55 mobo.

Good quality CAS 7 memory if you choose to use the i5:
G.SKILL Ripjaws Series 4GB (2 x 2GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Desktop Memory Model F3-12800CL7D-4GBRM - Retail

If not look for triple channel memory CAS 7 or 8.

HDD he mentioned:
Seagate Barracuda 7200.12 ST3500418AS 500GB 7200 RPM SATA 3.0Gb/s 3.5" Internal Hard Drive -Bare Drive

thnx for the suggestions but I was planning to upgrade to crossfire hd5850's later so then I would need the i7 and 850tc or not? and for the ram if I would buy an i7 wouldn't triple channel be better or is the difference small?

For a Crossfire setup you'd want at least 750TX. I think the 850TX is about the same price so you can stick with that.

An i5 is great for 1 or 2 video cards, but nothing more. If you decide to stay with the i7 you'd want triple channel memory.

Since Hyper-Threading and triple-channel memory offer arguably limited benefits in a number of applications, the only time we'd be concerned about selecting a Core i5 is if we plan to share those 16 PCIe lanes with more than two graphics cards. Testing has shown that two graphics cards can still perform exceptionally, even when limited to using eight PCIe 2.0 lanes each, so we're happy to employ the Core i5 for dual-card SLI or CrossFire setups, but not for triple- or quad-card configurations.

On the plus side, of course, compared to the Core i7 CPUs, is the price. The Core i5-750 2.66 GHz CPU costs $200, while the cheapest Core i7-920 2.66 GHz CPU weighs in at $80 more and won't offer a tangible performance boost over the i5 for most applications. Because we've chosen a simple two-card graphics configuration in CrossFire, the Core i5-750 is the obvious choice for this price bracket.

so you think the mobo can handle crossfire well?
February 28, 2010 8:11:36 AM

yes it will do crossfire quite well but it will take a hit if you go beyond using 2 cards
February 28, 2010 8:13:03 AM

All you have to check is that it has 2 x PCI-E 2.0 x16 slots (1 @x16 or 2 @x8, x8)

Ok thank you all for the help. I'll give the i7 i5 dilema some thought.

PSU - For a Xfire setup, a conservative choice would be a 600 watts PSU

http://www.amd.com/us/products/desktop/graphics/ati-rad...

ATI Radeon™ HD 5850 System Requirements

* 500 Watt or greater power supply with two 75W 6-pin PCI Express® power connectors recommended (600 Watt and four 6-pin connectors for ATI CrossFireX™ technology in dual mode)


I'd recommend the Antec EA-650EA or the Corsair TX650

MoBo - Expansion Slots....you have two x16 slots
PCI Express 2.0 x16 2
PCI Express x4 1
PCI Express x1 2
PCI Slots 2

Memory - DDR3-1600 at lowest CAS # you can afford:

CAS 6 - $ 249 http://www.newegg.com/Product/ProductList.aspx?Submit=E...
CAS 7 - $189 http://www.newegg.com/Product/ProductList.aspx?Submit=E...
CAS 8 $140 http://www.newegg.com/Product/ProductList.aspx?Submit=E...

Yeah I know the mobo has 2 slots, but I heard that for xfire a more expensive board would be better. And isn't the maximum ram clock speed that the i7 can handle 1066Mhz?

Would raid0 be any use to save money and improve speed?
