I'm Building my first gaming computer, im not the most familiar with computer parts but i've done tons of research and think I have found the parts, but i really dont know If these parts are going to work well together, ex: fan for cooling, more ram, faster hard drive, socket time.

These are the parts I was looking towards.

Case already bought with 450W

Intel Core 2 Duo E8400 Dual Core Processor LGA775 3.0GHZ Wolfdale 1333FSB 6MB

300GB VELOCIRAPTOR SATA II 10000RPM 16MB 3.5IN

DFI LP Dk X38-T2R ATX LGA775 X38 DDR2 2PCI-E16 3PCI SATA2 RAID Sound GBLAN Motherboard

EVGA E-GEFORCE 9600GT 650MHZ 512MB 1.8GHZ DDR3 PCI-E Dual DVI-I HDTV Out Video Card

OCZ NVIDIA SLI Ready XTC PC2-8500 2GB 2X1GB DDR2-1066 CL5-5-5-15 240PIN DIMM Dual Channel Memory Kit

And I dont know what to get for my cd/dvd drive.

go with lite on

Since you have a X38 motherboard picked, i'd suggest you go with an ATI graphic card so you can Crossfire them in the future (if you want to) so a HD4850 instead of the 9600GT. Basically any SATA burner. That velociraptor is a huge expense, make sure you really want it.

I will second that, yes its a very fast drive so yes your game will load damn quick , but you can get a quick drive for half that price and go get yourself a much better graphics card, its the card that really matters.

Agreed. There is little reason to spend so much on that hard drive, and then get a lower GPU.

Use the $$$ you save from the velociraptor and get a 4870 (or save some for a second one or the 4870x2)

Well the velociraptor was a suggestion, i also was looking towards the Western Digital Raptor 74GB SATA 10000RPM Hard Drive 5.2MS 16MB, but might be to low of memory, so i had the Western Digital Raptor 150gb, 10k rpm. If i were to cut off $140 from the velociraptor and get the raptor 74gb, would I put this towards
Gigabyte Radeon HD 4870 750MHZ 512MB 3.6GHZ DDR5 PCI-E Dual DVI-I HDCP HDTV Out Video Card.
And I have the money to spend a little extra on the cpu, would a better cpu be recomended?

Just wondering what case did you get that came bundled with a psu?

4870 won't work w/ a 450W PSU, the 4850 is VERY borderline there... what make is the case and PSU?

The first thing you should do is get a better PSU. If not doing CrossFire I recommend you get a PP&C 610 or a Corsair 550. If doing CrossFire (2* 4850) get a PP&C 750 or a Corsair 750TX.

Like every one said before, drop the VelociRaptor and get a better graphics card. Get a good 7200.11 HDD which are almost as fast as the old Raptors in most benchmarks.

Also be careful with DDR2 1066 RAM. Those RAM are known to have compatibility issues.

For quiet case fans look in to Scyth and Yate Loon. For a good CPU cooler I recommend the XIGMATEK S1283.

I changed things around I'm hoping to buy this for monday.

The case is ACHILLES Mid-Tower Gaming Case, 500W, mistake on the 450 W

Intel Core 2 Duo E8400 Dual Core Processor LGA775 3.0GHZ Wolfdale 1333FSB 6MB - $169

Western Digital Caviar SE16 640GB SATA2 7200RPM 16MB Hard Drive- $75

DFI LP Dk X38-T2R ATX LGA775 X38 DDR2 2PCI-E16 3PCI SATA2 RAID Sound GBLAN Motherboard- $189

Sapphire Radeon HD 4870 512MB GDDR5 PCI-E 2XDVI-I Video Card - $311

OCZ Reaper Hpc Edition PC2-8500 DDR2 4GB 2X2GB DDR2-1066 CL5-5-5-15 Dual Channel EPP Memory Kit $130

I'm trying to buy this setup as soon as possible, will this work out? Or do I really need to spend more money for a new Power Supply upgrading to a 750W, im hoping this computer will last so is there any more upgrades or replacements i should consider?

1. Be careful with DDR2 1066RAM. Those RAM have compatibility issues. Get DDR2 800 and OC it your self.

2. Consider getting X48 based motherboard if possible.

3. When getting a PSU make sure it is a good quality PSU. Check out the reviews at http://www.jonnyguru.com/ and also http://www.xtremesystems.org/forum [...] p?t=108088

For the 750W rage I recommend Corsair 750TX and PP&C 750.

4. CPU, HDD, and case looks fine. If OCing get a XIGMATEK S1283, providing it fits the case.
