Compatibility Prolems With My Proposed Computer?

[Shnissugah]

Im planning on building my first computer, and with the help of my friends I think I can do the building. The main issue right now is to make sure that all the parts are compatible with one another. Specifically the size (I hear it's huge) and power use of the GeForce 7950GX2 (SLI)(Newegg says it requires 550W for SLI but evga says 650), but really all of them. I'd be much oblidged if someone could double-check my work.
Here're the parts: (please bare with me, I pasted from an email then cleaned it up)

Looks okay to me. I've never used pqi RAM, so I can't vouch for them.

[jer888]

if your planning on buying ANOTHER one of those video cards then your going want to beef up that psu. if your getting only one then that should be fine

btw unless your using a ridicously large screen (30" or above) your not going to notice ANY advantage over using two single core gpus in SLI. quad SLI is pretty much pointless at this point until NVida releases its "new drivers".

Just that one.
Thanks for your help. Anyone know anything about the physical size problem of the card?

[blue60007]

I don't think it's any bigger than the dual slot cooler on the 7900GTX or the dual slot X850/1800/1900's

It's going to block the slot below the PCI-E x16 slot.

If you're going for a sound card, go for the X-Fi...you might even try the onboard sound (these premium boards have some pretty decent onboard sound) before getting a sound card. Also, you'll need a nice set of speakers/headphones to tell the difference between onboard sound and a high end sound card.

Also, you might as well consider a single slot motherboard. As jer888 said above, quad SLI doesn't do any good unless you're running at an uber-extreme resolution. There's just too much overhead juggling 4 gpu's.

Here's some good reads:

I haven't heard anything on pqi RAM either...you may look at Corsair RAM.

Get a PSU from PC Power & Cooling.
