[QUOTE=Kougar]This is true, from a brief googling I did. The XT looks to be comparable to a 5900Ultra, so it should definitely be way more power hungry.
The 5900XT is a downclocked 5900 (400/700 vs. 400/850), so it consumes less power. In the nVidia world, XT means inferior edition (I have a 5900XT).
Regarding the CPUs: I meant that the Northwoods need a lot of juice and the Core 2 Duos consume a lot less than the P4s. http://www.madshrimps.be/?action=get...35&articID=470

Okay, I found another review this time from Firing Squad and read through it, yer right. Maybe I saw 5700 Ultra listed and read it wrong, I'm not sure
The 5900 XT’s memory operates at 350MHz (700MHz effective), 75MHz below the 5900 Ultra and 125MHz slower than the 5950 Ultra. This provides the 5900 XT graphics core with up to 22.4GB/sec of peak memory bandwidth, the same figure as ATI’s RADEON 9800 PRO 256MB and 8GB/sec more than GeForce FX 5700 Ultra, which was the previous leader in this category in the mainstream segment.
Despite the slower memory frequency (700MHz effective versus 850MHz), the 5900 XT is able to keep up with the GeForce FX 5900 128MB in many benchmarks thanks to the lower memory timings its 2.8ns BGA memory boasts.
Due to the reduced frequencies of the graphics core and memory, 5900 XT board manufacturers are able to utilize a simpler board design with reduced power and heat requirements. An external power source is still needed, but the board requires significantly less power circuitry and smaller coolers. Video input and hardware monitoring functionality are also sometimes left out in order to further reduce production costs. Souce

Great site... Everything you can think of is covered me thinks

You asked the kind of questions good engineers would have asked. I noticed your profile said you're a student, please try for engineering or science as most real engineers and real scientists nowaday are imported from overseas or first/second generation Americans, and there aren't enough engineers and scientists right now.

This really is an awesome tool....I'm not surprised they included a pay version.

A while back, I was worried 600 watts wouldnt be enough for my rig.. but the calculator showed I needed no more than 300. Of course, it turned out that 600 was way more than enough. great calculator! tons of options.. but obviously better than some of the other PSU calc's i've run into

I wasn't sure if I had a big enough power supply but I found out that I should be good, just no more upgrades

My new core i7 GTX 295 says I need 607 watt. If I don't use the GTX 295 and use the GTX 260 it says I need 484watts. Either way I am good to go with my PC P&C 750.
