sorry i copy pasted my list of components from excel and it became hard to read, i apologize about that. thanks everyone for their quick replies. I'm actually trying to build a PC that can last me at least 4 years, and that I can easily upgrame when i becomes neccesary.
This is my latest list of components:
CASE: Cooler Master HAF X
RAM :Corsair DDR3 1600MHz 6GB 3x240 DIMM Unbuffered
CPU: Intel Boxed Intel Core i7 Extreme i7-980X 3.33GHz 12M LGA1366 Gulftown BX80613I7980X
SSD (for running Windows XP and booting Windows 7 from Windows XP) Intel Boxed X25-V Value SATA SSD 40GB SSDSA2MP040G2R5
DRIVE: LG Blu Ray Drive (GGC-H20L)
MOTHERBOARD: GIGABYTE GA-X58A-UD7 motherboard
GRAPHICS CARD: MSI graphics board for NVDIA N480GTX-M2D15
WIRELESS: BUFFALO Air Station NFINITI 11n/g/b USB用 無線子機 WLI-UC-G301N
PSU: GALAXY EVO EGX1050EWT (i think this is only available in Asia??)
STORAGE DISK: WESTERN DIGITAL 3.5インチ内蔵HDD 1.5TB 5400rpm 32MB SATA 3.5inch WD15EADS
I'm a little bit afraid the 40GB disk won't be enough to run all my applications, but that's what I can buy. By the way, my budget is around 2500 USD. All the things will be bought in Japan, cause i'm now in Japan.
Also, I hope the 5400 disk is fine.
I would like to use the computer for gaming, CAD programs, and Adobe CSU suite. Also my gf is an architect and she has to run simulation programs that usually take like 12 hours to complete with a dual core, stuff like that.
how much better does it get by adding 2 GTX460 in SLI? what if I use only one 480GTX in SLI and then add another GTX 480 in a couple of years? btw how many cards in SLI can I add?
I decided I won't relly burn blu ray so I changed the drive and i got much cheaper..
looking forward to hearing more advice, thanx, cheers
