Building new machine—questions inside

Sup All—So I am finally after all these years building a new machine. My dinosaur that I built in college is finally starting to die out. No more memory patches, upgrades etc … :frowning:

Anyway—I am rejoicing because in 2 weeks bells and whistles will whirl!

Here is what I am ordering.

[SIZE=1]– Rosewill R5717-P BK 120mm Fan ATX Mid Tower Computer Case

[SIZE=1]– GIGABYTE GA-MA790FX-DS5 AM2+/AM2 AMD 790FX ATX AMD Motherboard

[SIZE=1]– Leadtek GeForce 8800GT 512MB PCI Express 2.0 HDCP Ready-SLI[/SIZE]

[SIZE=1]– Thermaltake Purepower W0129RU ATX12V 600 W Power Supply[/SIZE][SIZE=1]

– AMD Phenom 9500 Agena 2.2GHz Quad-Core Processor[/SIZE][SIZE=1]

**– G.SKILL 8GB(4 x 2GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400)

[/SIZE][SIZE=1]Seagate Barracuda 7200.10 ST3250410AS 250GB

[/SIZE]**[SIZE=1]I have an older 320g IDE HD that I will be making a slave HD. Already have a dvd-r drive.

[SIZE=2]My question is—Windows XP 64-bit or Vista 64-bit?[/SIZE]

What will utilize the ram better? XP or Vista?

*Side note: Went with the DDR2 800 ram to save a few bucks vs. the 1066. Plus with this motherboard, I would have to flash it to run 1066 ram. Not the end of the world, but just saving a few bucks.

My budget is 1000.00. This goes over by $60.00. If anybody has anything to suggest or add let me know. :smiley:

edit: I’ve always been a nVidia & AMD kind of guy. Suggesting intel or ATI isn’t out of the question, but more than likely I won’t lean towards that direction. :smiley: haha
