Wow, you guys and XFX are awesome, though they should have a double lifetime warranty on their PSU's like their graphics cards.
Let's see... a 750 Watt PSU.
I'm pulling 830 Watts from the wall with my i7 950 overclocked to 4.37GHz and two overclocked GTX 460 1GB's in SLI at 960MHz Core Clock while running FurMark AND Prime95 at the same time. Since I know the i7 2600k is more efficient, pulling 100 Watts less on full load at 4.6GHz than an i7 950 at 4.37GHz...CPU
: i7 2600K @4.6 GHz w/HT watercooled with a 120.2 Swiftech Ultima XT and four Noctua NF-P12's in push/pull using a Swiftech MCP 655-B pumpMB
: ASUS P8P67 Deluxe - Revision 3Memory
: Kingston HyperX 2x4GBGraphics
: XFX Dual HD 6970 2GB Crossfired with full cover water blocks (still covered under warranty since I'm residing in North America - yay!). It's a shame XFX never made any GTX 460 1GB's, but I've been eying the XFX HD 6970's (because of their double lifetime warranty).SSD (OS)

: RAID 10 4x1TB Samsung Spinpoint F3PSU
: XFX Pro750 WattCase
: LIAN LI Lancool PC-K62 - Gotta have a clear side panel to show it off.
The power consumption of an overclocked HD 6970 2GB's closely matches that of an overclocked GTX 460 1GB. Now, I'd probably be hitting the limits of the PSU, but I think it can handle it. They should let me win so I can find out.
