Building a new computer (first time builder) - seeking advice on selected parts

[dopout]

I'm making a gaming computer. I spent a long time browsing newegg looking at parts, looking up things in descriptions and specs that seemed important, and trying to make sure what i was looking at was all compatable together.

I would appreciate confimation of the compatability of the parts, open to suggestions of changes/reasons. the HD comes bare so i also put a sata cable in the order, was this nessesary? or would cables for that come w. something else like the motherboard (ie: i shouldnt need to buy ne extra cables)?

here are the parts i picked:

Processor: Intel Core i5-750 Lynnfield 2.66GHz 8MB L3 Cache LGA 1156 95W Quad-Core Processor BX80605I5750

Motherboard: GIGABYTE GA-P55A-UD3 LGA 1156 Intel P55 SATA 6Gb/s USB 3.0 ATX Intel Motherboard

RAM: CORSAIR XMS3 4GB (2 x 2GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Desktop Memory Model CMX4GX3M2A1600C8

Power supply (650 should be plenty?): CORSAIR CMPSU-650TX 650W ATX12V / EPS12V SLI Ready CrossFire Ready 80 PLUS Certified Active PFC Compatible with Core i7 Power Supply

Hard drive (i should buy sata cable to be able to hook it up?): Western Digital Caviar Black WD1001FALS 1TB 7200 RPM 32MB Cache SATA 3.0Gb/s 3.5" Internal Hard Drive -Bare Drive

sata cable for hard drive?: OKGEAR 18" SATA 6 Gbps Cable, Straight to Right Angle W/Metal Latch, Silver, Backward Compatible with 3 Gbps and 1.5 Gbps - OEM

Video Card: recycling my ~6month old Geforce 9600 GT by PNY

Sound Card: Should i get one?

Are there any parts i didnt look into and list that i should? (i have a 19" screen ill recycle into the new build, g5 caming mouse already, my dell keyboard suits me fine, as well as speakers).

windows 7 seems to be the operating system to go with?

thanks for your help and advice

Although normally you would need a sata cable if you get an OEM drive, your motherboard should have them. Speaking of your motherboard, you should change from the Gigabyte brand to an Asus. If the motherboard has onboard sound, you might not need a soundcard. Onboard sound is better than it used to be. You could try it and add one later if you aren't happy or have special needs in your usage.

EDIT: Looking at your list, you could switch the motherboard to one of the ASUS P7P55 boards. (See which one has what you need.) It appears the memory and processor you chose will work with it. You did seem to mostly pick out quality parts. You should wait until someone who knows more than I posts here, but I am giving you advice that I think is good and accurate. If you get Win 7 and you want, you could double the amount of memory you get, however.

BTW, this will be probably be moved to the build your own PC section, but there will be a link here saying moved and leading you there.

Recommend these adjustments:

1. Upgrade to the i5-760 processor.
2. Change the motherboard to an Asus P7P55D-E.
3. Change the hard drive to the SATA 6.0 WD Black.

A 9600GT doesn't make much of a gaming computer these days, by the way. HOWEVER - you could get an Asus P7P55D-E Pro board and another 9600GT, and run them in SLI. If you do that, I'd recommend you upgrade the PSU to the Corsair 750TX.

I haven't seen a motherboard in a few years that hasn't come with at least 2 SATA data cables.
