Enough power for Gigabyte GeForce GTX 780 WindForce 3x "GHz Edition

Thanks mate, I am guessing 6+2 pin PCIE cables are the same as 8 pin ?

Many thanks Dunlop0078 just have to decide if its worth upgrading form my GTX570 now.

I suggest waiting for the new MAXWELL cards. The GTX880 (4GB?) is estimated to start at $500 and may be available this October.

Rough estimates put it as powerful as a GTX780Ti top-end card. The power is much lower than existing cards at this level. We already know this from looking at the GTX750Ti.

So the GTX880 compared to the GTX780:

a) will have more processing power
b) should use the same or less power
c) should be the same or quieter with a good cooler
d) may have 4GB vs 3GB
e) should do even BETTER slightly once software is optimized more for the Maxwell architecture

I see what your saying but, in this game you can always be waiting for the next component to come along some times you just have to jump in. I've been reading on another http://www.tomshardware.co.uk/answers/id-2190900/650w-psu-gigabyte-nvidia-geforce-gtx-780-ghz-edition.html they are stating that a 650w PSU would not be enough to power the card, I am a little confused now.

Update:
I looked at your link again. The "best answer" guy is totally out to lunch. For easy reference, here's the power breakdown:

Motherboard for graphics: 75Watts max
6-pin: 75Watts max
8-pin: 150Watts max

So, a GTX770 that uses a 6-pin and 8-pin has up to 300 Watts available though it will use less. I have absolutely no idea where that guy came up with 600W for a GTX780 but he's not even close.

*I built my dad an i5-4670K system and it uses about 100Watts with the CPU at 100% (it has no graphics card).

Yes I have waited a while, a couple of months ago I did a full upgrade (apart from GPU & PSU) of my system, so I spent quite a bit of money then. I think I will hang on to see what the GTX880 is like, I also want a new monitor the spending never stops.
Thanks again guys for the sound advice.

I know what your saying, I've tried the PS4/Xbox 1 gaming route but they are not a patch on a well specked PC. Looks like GTX880 hear we come, just have to hide card receipt from the wife. Any ideas on a good monitor around 22 inch to 24 inch, £200 ish not bothered about 4k ?

Thats why id do it gotta have the best of the best. As far as a monitor idk there are too many options in that price range i prefer a 1080p with low response time and i prefer an IPS screen.

What is "the best of the best?"
The short answer, IMO, is the new Asus ROG Swift (G-Sync, 2560x1440, 120Hz+... ).

There are PROS and CONS to every monitor. You actually summed up the main pro and con when picking a monitor. IPS panels on average have better color, but they also have higher response times which produces more ghosting. Response times are how long each pixel takes to change color (it's not instantaneous) and IPS panels are slower.

Not sure why you said "1080p" as 2560p (2560x1440) is a higher resolution. Response times (pixel changing color) aren't related to the screen resolution so the higher the resolution the better You can still send the monitor a 1920x1080 signal if your computer couldn't keep up with 2560x1440 to produce the highest FPS (i.e. 60FPS). My only issue with 3840x2160 is it's barely better than 2560x1440 in resolution, likely to have other issues, costs more, and to my knowledge has no G-Sync option.

Some people avoid high resolution due to the SCALING ISSUES. That's easily solved by adjusting the DPI in Windows (choose between 25% and 40%); for a browser you can use an addon in Firefox like NoSquint to preset (i.e. 180%) and for individual pages just use CTRL+Scroll (browser should store individual page changes). Simply put, higher resolution is better.

It's also a bit more complicated than this because there's more going on than just the type of panel. It's important to note that a really good QUALITY TN PANEL is quite excellent quality, whereas low-quality IPS panels have issues.

*Long story short, the ASUS ROG SWIFT 2560p monitor is the best monitor for gaming you can buy.

I'm not saying to buy it just responding to your statement of getting "the best" and the best gaming monitor is the ASUS ROG SWIFT hands down. I believe it just started shipping.

G-SYNC is not some minor gimmick. It's really, really amazing technology for producing the smoothest game experience whilst minimizing lag and worrying about meeting a particular VSYNC cap (to avoid screen tearing).

(The only thing I'm not certain is the anti-glass technology. Someone said it's NOT a glossy screen calling it a "POS" because of that. Well, glossy is idea if there's almost no light like in basement but you need some sort of anti-glare technology if like most people you have some light that can reflect. So for most people this would be ideal.)

SUMMARY:
I personally would NOT get the SWIFT yet, and definitely not sight unseen. While G-Sync is a game changer for this much money I'd like to see it on IPS with a lower response time (3ms or less), or else increase the TN panel viewing angles to be better. That's assuming everything else is up to snuff. For gaming monitors unfortunately it boils down to a choice between GHOSTING with IPS and Viewing Angles with TN panels and deciding which is the least evil.

There are some very inexpensive 1080p monitors ($125 USD) with good customer reviews which I'd probably recommend for a year or so to see if we can G-Sync in a better gaming screen.
