Default How will the monitor affect performance in games

Dear all,
some time ago we bought a new TV and I tried to connect it with my PC and I gotta say the image quality was godlike compared to my old LG Flatron L1953TR 19". So I decided to get a new LCD for my PC.
Which one would you recommend? I do not need anything huge and with price under 200USD. Or is it worth pay more than that?

But there is one thing that concerns me - will the bigger LCD with better resolution affect performance in games?

My setup:
CPU: i5-2500K + CoolerMaster Hyper 212+
MB: ASUS P8Z68-V PRO - Intel Z68
GPU: EVGA GeForce GTX 970 FTW ACX 2.0 4GB
RAM: Corsair Vengeance Black 8GB (2x4GB) DDR3 1600 CL8
PSU: Corsair Enthusiast Series Modular TX750M 750W
HDD: WD Caviar Black - 1TB
CASE: CoolerMaster HAF-922 (RC-922M-KKN1-GP)

Thank you for your further replies.
Best Regards,
DZImmy

Size doesn't matter, only the resolution affects framerates in games. You could 1080p easily on a GTX 970.

Currently I am using 1280x1024 and I am afraid increasing the resolution will dramatically affect the performance.

If you're at 1280x1024x60 and you're going to 1920x1080x60

1280x1024x60 = 78,643,200
1920x1080x60 = 124,416,000
(124m / 78m) * 100 = 158%
Thats a 58% increase in output trying to maintain 60 fps so you'd have ~50% less performance moving from what you have up to 1080.

A 970 can handle it just fine, though.

iParanormal: WOW! Is that really that huge difference? I didn't expect that, since I did no math. :P

carnageX: But it depends if it can handle it in future games. Or even in recent ones I am having frame drops, I am affraid it will go worse.

You're having frame drops because at such a low resolution the CPU is doing most of the work. Higher resolutions are GPU bound. A 970 handles every game out right now 60fps + @ 1080p.

@PP Mguire: How come? I've never heard of that? iParanormal's post seem to say the opposite. :/

Lowering the resolution of a computer game or software program increases the effect on a CPU. As the resolution decreases, less strain is placed on the graphics card because there are fewer pixels to render, but the strain is then transferred to the CPU. At a lower resolution, the frames per second are limited to the CPU's speed.

CPU sets the frame up + handles all the AI/resource allocation and then passes the parameters to the GPU which then draws the frame. So the CPU does its thing sends the frame along to the GPU. The larger the frame and the more processing required the longer it takes for the GPU to finish. At low resolutions the frames are drawn much much faster therefore the CPU has to do a lot more work setting up more frames.

I have a 970 in my house, and Carnage has a 970 in his rig both machines pushing 1080p screens. They're perfect for that res.

@PP Mguire: That is really interesting.
"At low resolutions the frames are drawn much much faster therefore the CPU has to do a lot more work setting up more frames." - wouldn't it mean lower FPS? I mean in case I have VSync on capped on 60FPS the CPU would have the same amount of work at any resolotion, wouldn't it? So setting a higher resolution will actually hurt the FPS and won't help the CPU in case I have it capped on 60FPS. Theoretically.


I am not saying you are not right (or arguing with you) nor the GTX970 will not handle it, I am just really curious, since this is very interesting.

Btw. could the bigger screen affect the annoying coil whine?



Anyways, what LCD would you guys recommend?
