Tearing apart XPS-710, new case, mobo, psu!

[Dakir]

Hello! As the title says I'm in the process of tearing apart my Dell XPS-710 mainly because its using a BTX layout motherboard and I just got a EVGA nForce 780i from a buddy, brand new for really cheap. Whats interesting is cpu-z says I have a nForce 570i, but on dell's website it says all XPS-710's have a modified nForce 590i, and im not really sure which i have but it doesent matter cause its BTX and i'm replacing it.

current build: Dell Xps-710
nForce 570i or 590i
Geforce 8800gtx
2gb ddr2 667mhz memory
1000w psu
Core 2 quad, q6600 B3 processor
Sound Blaster X-Fi Xtreme Audio


new build: Custom
Antec Twelve-hundred case
EVGA nForce 780i
Geforce 8800gtx
2gb ddr2 800mhz memory(maybe)
Core 2 quad, q6600 B3 processor (with Xigmatek S1283 cpu cooler since the dell one doesn't fit on the 780i)
Sound Blaster X-Fi Xtreme Audio

Im not exactly sure which PSU i want between:

and
http://www.newegg.com/Product/Product.aspx?Item=N82E16817139006&Tpk=750w

Iam going to be either upgrading video cards in the future or throwing another 8800gtx in.

Opinions, Suggestions?

Thanks,
Brett

I think either PSU would be fine. They are both considered top tier PSU's. By my calculations, with two 8800 GTX you will need around 750w for the PSU.

I would go with 4 gigs of DDR2 800 memory. 2 gigs will not cut it for your build.

Otherwise, no more suggestions.

The corsair 750w tx is cheaper on buy.com I think it's 109 -20 mail in rebate and free shipping.

I've been told very mixed reviews about corsair and ocz and have no idea which company to buy. I don't want dominator or any of their super overpriced stuff. Link me a solid dual channel 4gig(2x2gig) pair that oc well please.

Corsair makes the highest quality and most ripple free PSU's in the industry.
4GB of DDR2 800

Both that PC P&C and Corsair are good.
Personally id get the Corsair, more watts and better $$/Watt

In terms of one being better....theyre basically the same
But to what Crysis said, they are not the most ripple free, from reviews ive read atm the Antec Signature wins in ripple but Corsair is solid, but not best

could i use either of those PSU's in my standard XPS710 Chassis ?
My Dell one has failed i just get a orange blinking light on the front of the base unit.
