Would a i7 920 at 2.67 ghz (stock) be sufficient to run sli'd 460's? And when I say sufficient I mean, no bottleneck what so ever.

My specs:
Windows Vista 64bit home premium
ASROCK X58 deluxe mobo
Intel core i7 920 at 2.67 ghz quad core
SLI'd EVGA nvidia gtx 260's (216 superclocked model)
OCZGXS 700 watt PSU (soon to be replaced with Antec 1kw)
OCZ Gold 6GB (3 x 2GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800)
10000 rpm raptor hdd

Yeah, but check on the 930, you might be able to get it for the same or cheaper.

Are you making any other changes so that you'd need a 1KW PSU?
GTX 460 actually uses less power than the GTX 260s. Even the factory OC'd GTX 460 models are only a few watts more in some cases than the stock 260s. Your 'superclocked' GTX 260s probably use more power than the 460 replacement's would use.
GTX 260 vs GTX 460 power reqmnts

With no bottleneck? They're not 'magic' video cards so don't expect miracles - they're just a bit more powerful video cards.
You can look over the gaming benchmarks in the rest of that article linked above. Here are some 460 SLI benchmarks.
What screen resolution do you use?

Well at the time when I built the system I thought the 700 watt was pushing it for sli and a core i7. I figured a 1000 watt will cover me more than enough now and down the road.

As for the 460, I originally wanted to replace my sli'd 260's with a single decked out 480. Upon learning that 2 good 460's would do quite a bit better for less $$$ I have opted for them. I didn't follow you with the whole "With no bottleneck? They're not 'magic' video cards so don't expect miracles." What do you mean magic, I am not out to build an 8 grand behemoth of a gamin pc with sextuplet sli, just something that gives me a healthy boost over my current config.

I really do not want to OC, thats why I am asking if the 920 at stock speeds should not be a bottleneck to the sli'd 460's I intend to install.

Thanks alot for the info though, I am just a little confused.

ps, 1680x1050

I have been given some differing answers when it comes to will sli'd 460's bottleneck a i7 920 at stock speeds, can anyone answer this definitively?

Thanks

No they won't be bottlenecked, and yes don't waste money on a 1kw PSU. You will notice a nice fps in games with 2 GTX460's over your current 2 GTX260's.

It will not be bottle necked by the i7 920. And if you got a monstrous graphics configuration like lets say 4x GTX480's then even if the 920 did bottleneck them, which it probably wouldn't, you can easily overclocked it...and I am not kidding, like ridiculously easily overclock it on air to way past 3Ghz+.
