Dual Monitors Impact Performance?

Ok this coming September I am going to come in a bit of money, around £2000. I plan to build a gaming PC, I gave myself a budget of no more than £1,300. Here's the plan so far:

i7-4770K 3.5GHz Quad-Core
Corsair Vengeance 16GB (4 x 4GB) DDR3-1600
Samsung 840 EVO 120GB 2.5" SSD
Seagate Barracuda 1TB 3.5" 7200RPM
EVGA GeForce GTX 770 2GB Superclocked ACX
Microsoft Windows 7 Professional SP1

So currently I have just a generic 1080p acer monitor, and I thought I might replace it with a Asus VS247H-P. Then I thought what is the point in chucking my old monitor away when I can have both! So here is my question, if I use the ASUS to play video games on, and use the acer to browse the web, watch a video, play music, skype or maybe streaming software like OBS or xsplit open what ever it may be. I know it will affect performance but by how much?
Obviously you can tell I'm trying to get the best performance for my money, I think this build will come to about £1,100ish. I've never used a good PC system like this, so I'm unsure on how powerful it will be and if a 2nd monitor will have a noticeable impact on performance.
Thanks! <3

  1. Performance may depend on the games you run.

    One thing you may notice when playing a full screen game. things on the second screen will either just stop or show down when gaming. This is the video card dedicating most of it's resources to the screen you are gaming on.

    Now running games in a Window reduces and eliminates this for many games.

    Fake full screen/ boarderless window can give you the full screen effect with faster alt tabbing and performance under some circumstances.

    In a worst case, you can always disable the extra screen in the Nvidia software or even Windows resolution panel before playing a game that has issues with multi monitor.

    I think overall your experience should be good.
  2. If you're buying this PC in september, I would recommend getting the i7-4790k instead of the 4770k (Should be around the same price). Also, make sure you pick up a z87z97 motherboard for the 4790k (or 4770k) and get a good cooling solution for the CPU.

    Also remember not to skimp on the PSU, get something at least Tier 2 class B on this list http://www.tomshardware.co.uk/answers/id-1804779/power-supply-unit-tier-list.html

    Ok thank you for the reply so fast lol!
    Pretty much answered my question.

    To be honest thinking about it, I rather multitask on 2 monitors and get at least 60 fps in game (example: metro last light) then to only use 1 monitor and get like 100 fps. Although I think the EVGA GeForce GTX 770 2GB should be fine, its only 1080p anyway.

    Thanks for the reply!
    Whats the difference between the i7-4790k & the 4770k? Also which z87z97 motherboard would you recommend?
    The current motherboard selected is - Gigabyte GA-Z87-HD3 ATX LGA1150 Motherboard
    CPU Cooler - Cooler Master Hyper 212 EVO
    PSU - Corsair CX 600W 80+ Bronze Certified Semi-Modular

    Hyper 212 EVO is a great air cooler, use it myself :) Basically:

    The i7-4770k is intels Haswell i7 CPU. the 4790k is intels Haswell Refresh CPU. The 4790k has a stock clock of 4.0GHz with a turbo clock of 4.4GHz, compared to the 4770k's 3.5/3.9. the 4790k also has better thermal compound between the heat spreader and die, meaning better temperatures and, therefore, better part longevity or overclocking.

    That gigabyte motherboard should be fine, though I would say have a look at its z97 equivalent for some better features

    Looks good, but you said you have a £1300 budget, you could probably get a 780 over a 770, just be sure to upgrade the psu if you were going to do so

    Well the money is from student finance so I need to save as much as possible, but I also have a part time job so I could probably go over £1300. Its just I don't really want to xD Maybe a 780 or even 780ti for a future upgrade!

    Ahh fair enough, i'm a student myself :P stick with the 770 then, tbh in september the 870 might even be available :P
  10. WAIT! New G-Sync monitors are now out for sale and coming soon are AMD's Free-Synv, and a new VESA standard called Adaptive-Sync, so all this competition will start a price war!!
    You will get much more out of your graphics card with one of those monitors. Also I use a Sapphire R9 290 Tri-x and use 2 monitors and the spare one just switches to a black screen for high end games like Rome II, BF4, Crysis 3, Arma 3 etc. But stuff like Eve online (even maxed out) in window mode lets me use both screens so I can check forums and watch youtube videos etc.
