x48 or p45 for new build?
 
So I'm grateful to everyone who helped me out choosing parts for the new PC I'm about to build. The parts I have chosen are the following:

RAM: Mushkin SP PC2-6400 4GB 2X2GB DDR2-800 CL5-5-5-18 240PIN DIMM Dual Channel Memory Kit
http://www.ncix.com/products/index.php?sku=27234&vpn=996558&manufacture=MUSHKIN

CPU: Intel Core 2 Quad Pro Q9550 2.83 GHz Quad Core Processor (1333 MHz 45NM) Socket 775 (12MB L2 Cache)($359.95)
Buy Intel Core 2 Quad Pro Q9550 2.83 GHz Quad Core Processor (1333 MHz 45NM) Socket 775 (12MB L2 Cache) - BX80569Q9550
Some of you suggested a dual core, but I'm not exclusively using this system for gaming so it will come in useful for the applications I run.

Case: Coolermaster Cosmos Full Tower ATX Case 5X5.25 6X3.5INT No PS Front USB Firewire Audio eSATA ($192.66)

GPU: ATI 4870

HD: Seagate Barracuda 7200.11 3.5IN 500GB SATA2 8.5MS 7200RPM 32MB Cache NCQ Hard Drive OEM ($89.00) x 2
http://www.ncix.com/products/index.php?s...facture=Seagate

PSU: Corsair TX750W 750W ATX 12V 60A 24PIN ATX Power Supply Active PFC 120MM Fan ($105)

Sound Card:HT Omega Striker 7.1 Channel PCI Sound Card 24BIT DTS Dolby Digital Live S/PDIF IN/OUT Coaxial

OD:Pioneer DVR-216DBK Black 20X SATA OEM DVDRW No Software

Now for the mobo. I was going to go with SugarJ's suggestion in getting a
ASUS P5Q Pro ATX
(NCIX.com - Buy ASUS P5Q Pro ATX LGA775 P45 DDR2 2PCI-E16 Crossfire 3PCI-E1 2PCI SATA2 Sound GBLAN eSATA Motherboard - P5Q Pro In Canada.).

But I heard that p45 boards don't offer full x16/x16 PCI-E bandwidth in Crossfire. Since I plan on getting another 4870 as time goes on, should I get an x48 board instead, which does offer x16/x16 bandwidth?

Which x48 mobo should I go with if that's the case?
Gigabyte X48-DS4
http://www.ncix.com/products/index.php?sku=29821&vpn=GA-X48-DS4&manufacture=Gigabyte

or should I stick with the Rampage formula?
NCIX.com - Buy ASUS Rampage Formula X48 ATX DDR2 2PCI-E16 CrossFire SATA2 RAID Sound GBLAN Motherboard - RAMPAGE FORMULA In Canada.

Since the heart of the computer is the mobo, I don't want to skimp out and be restricted by it.

Any suggestions?

On a side note, whats the general opinion on the Raptor drives? Worth it for the price? Or just stick with a 7,200rpm HD?

Thanks again! I love these forums. I've been out of touch with computers for a while but I'm making a comeback and its nice to see that you don't get treated like a stupid newb here.

I'll weigh in on this again, if I can. :biggrin:

The P45 is a PCI-E 2.0 motherboard, which runs x8/x8 in Crossfire. This is equivalent in bandwidth to PCI-E 1.1 x16/x16. Currently, the 4850 and 4870 are not in danger of saturating the bandwidth.

If I recall correctly (I've given advice on 4-5 builds in the last couple of days), you had picked a Rampage Formula, but weren't planning on overclocking? So I suggested a board which would save you money and still do all the requirements.

Those X48 boards you've mentioned are both good boards, but might not be worth spending the extra money if you still don't plan on overclocking.

As for velociraptors, if you have an unlimited wallet, go for it. But you likely would not notice much improvement in day to day tasks unless you are copying large files on a regular basis.

Personally, when it comes to high performance drives, you still cant beat U160 or U320. Its just finding a decent scsi controller card is a little more time consuming. SCSI smokes ANY sata drive hands down. Or if you wanna load HL2 in like 10-15 seconds, get raid 5 SCSI

Well exactly what he said, I'll just add one thing, Raptors are good, but those new 2 platter hard drives like the WD or Seagate 640Gb, why not just get 2 x ITB hard drives and RAID them.

Are Raptors worth it? Hmmm, the answer would be, it depends.

I went through about a dozen reviews yesterday, mostly the new Velociraptor
and its damn impressive, pretty much on par with many SSDs when in raid0

imo, if all your looking for is load times into memory for games and common apps,
forget it, an extra 2 or 3 seconds isnít worth it, its just a one shot rush.
But if you have applications that access many files and often, like databases, servers,
or real time coding tools (object reference popups as you type), itíll be well worth it.

I say get the ASUS P5Q Pro and call it a day. P45 chipsets go 8X/8X when in Crossfire mode. And since it's PCI-E 2.0, it should have more than enough bandwidth to suit your needs.

Don't get the Raptors. I don't think they're good bang for buck. I agree with DK2 on his post on the Raptors. NCIX.com - Buy Western Digital Caviar SE16 640GB SATA2 7200RPM 16MB Hard Drive OEM 3YR MFR Warranty - WD6400AAKS In Canada. should be good enough for you. I believe it's the fastest 7200RPM hard drive.
