I recently bought AC4 and found my GPU reaches heats of around 80 Degrees while playing it on resonably high settings, this seems a little excessive, despite it being a next-gen game, I have a gtx 770 an intel i5 3570K and 8GB of ram and a lot of games dont seem to perform as well as they should, this may be a really dumb question but I'm still relativley new to this kind of thing, will the fact that I have essentially 4 monitors connected all the time damage the performance of my PC?

Resolutions and connections:

Main Display: 1920x1080, HDMI to GTX 770
Second: 1680x1050, VGA to GTX 770
Third: 1024x768, VGA connection to my on board graphics (I dont use it for much and it's a very old monitor)
Final: 1024x768, DVI to GTX 770 (Projector I use for films and such)

Am I dumb for mixing GPU with CPU graphics? Should I unplug ones not used while gaming? Or am I just being silly?

My board is an asrock 7zz extreme4 if it matters, CPU cooling should be fine I have a hyper 212 but the model I bought of my GPU only has one fan, this is a picture of the model I have: http://www.evga.com/products/images/gallery/02G-P4-2770-KR_XL_7.jpg


Also, if these stats are normal and I'm just being paranoid, could I start gaming on all 3 of my monitors at the same time? Will that destroy my computer or not really matter because it's all being rendered anyway? Could I game on 3 monitors with one of them being attached to on board graphics, would the GPU you able to send the render info and run the game and the CPU just display it or does it not work that way?


Can I SLI different GPU's together, do they both need to be GTX 770's or both the same model?


Thanks in advance,
Padrig

I can answer some of your questions... having multiple monitors will reduce your performance because of more demand on your GPU which will also give you higher temps than with only one monitor (even at idle the difference is quite big), so taking into account your 3 monitors and the cooler your GPU has I'd say that's an expected temp to reach.

You could try gaming with only one monitor attached to see if you can get games to run as you expected them to be.

Damage your pc........ not really unless you let temps get really high (100ºC+) on your GPU or 70ºC+ on your CPU.

As for SLI, you have to use two GPUs of the same model (it could be 1xGTX770 from MSi and 1xGTX770 from ASUS).

You should be able to run 3 different games at the same time, but again, having 3 games + 3 monitors loading your GPU you might not get the performance you want.

Thank you so much, I thought I might just be being paranoid, will it be worth unplugging some monitors when I game, will 70-80 degree temps damage it at all? Even if it only takes a month off the lifespan of the GPU, I can go 10 mins without facebook or whatever.

I wasn't clear enough with the game son multiple monitors, I've seen people put one game on all 3 monitors, stretched across, could I do that with one of the monitors connected to on board graphics?

Thanks again

70-80 ºC is well within acceptable levels, try looking how many FPS you get when playing with all monitors connected and then again with only 1 monitor connected, it will be up to you to see if the FPS gained is worth it or not.

Most likely you won't be able to stretch the game above all 3 monitors while having one to the on-board graphics, though you could have 3 monitors on the GPU and play on it and have the 4th for desktop with your on-board chip.

If your gaming across multiple screens then obviousely performance will be impacted, if the other screens are just sitting at desktop then there shouldnt be any significant impact, especially if some are running off the iGPU.

Running a game across the screens wont damage your machine. Though for Surround to work they all need to be plugged into the GPU, and apparently all the displays have to be roughly similar to each other.

You can only Crossfire/SLI the same cards, eg; a 770 and a 770, brand and model doesnt matter.
There are a few exceptions, where their different models but have the same GPU, but that's only on the other side of the fence (AMD, you can crossfire a 7970 and 280X).
