Hello.
I recently (read: 5 hours ago) added a GTX 670 2GB instead to replace a 560 Ti and I having weird lag. It only lags in games, and it only seems to be in CPU heavy games or something. Everything I do seems to have been slowed down as well. When I played Metro: Last Light I experienced no lag, and parts where I used to lag are completely fine now. I have around 150 FPS in Team Fortress 2 but it feels like 25, and in Garry's Mod the lerp is going crazy, as well as the FPS being unstablwe as hell.
Battlefield 3 is slightly better than the 560 Ti was but Battlefield: Bad Company 2 is like 20 FPS (haven't benchmarked).
Anyone know what this could be and how to fix it?

Oh yeah, and one of the reasons I suspect it being the CPU or something is because I can stream a video in HD on my second 1920x1080 monitor and have no difference in the frame rate.
What do you mean by "lag"?
Is it a constantly low framerate, occasional framerate hitches, or even just a delay between doing something and seeing it happen on the screen?
Also, are you on the latest drivers? And do you still have the 560 installed, or just the 670? Your post is a bit unclear.

I only have the 670 installed. The "lag" is different for different games. In Garry's Mod it lags when I look at different parts of the map (however acceptable cause you know that's how it is sadly)
Team Fortress 2 has a constant 'low framerate' lag yet I have ~150 FPS.
The delay used to happen sometimes with the 560, but I don't recall having that issue here.

The card has been lying in our garage for 1 month or so, is it possible that his damaged the card?
I doubt the card would've taken any damage from just lying around in the garage.
Here are the steps/checks I would do (Might be a bit of an overkill, but use them as a last resort):
1. Make sure you have a good enough power-supply (PSU) for the new graphics card.
You will be able to see how many watts (W) your PSU has by opening up the PC and look at the very bottom back corner (Can be at the top aswell).
The PSU looks like this: [URL="http://images.tweaktown.com/news/1/9/19894_01_ocz_power_up_psu_line_with_new_fatal1ty_and_zx_models_full.jpg"]IMG[/URL]
If you cannot find anything on about watts on the PSU, simply google the product ID which is shown on the PSU itself.
Lastly, do a complete list of your computer specs and google specifications and add up the watts usage and see if your PSU has enough power to supply all the hardware.
2. Make sure everything's plugged in and, most important; make sure the GPU haven't suffered any damage while you plugged it in. One has to be very careful when unplugging and plugging in new hardware.
You will be able to see if any pins or other small objects has been damaged on the GPU itself.
3. Run a stress-test on your GPU and see if it's stable. Simply google graphics card stress test and you will find some general information about it.
If the result graph of the stress test show that the GPU is unstable, there might be dust interacting or it's damaged.
Beware: Make sure you have good cooling as the stress-test [B]will[/B] heat it up quite good. This step is at your own risk.
I expect that you've already checked the drivers and know they're up to date and compatible.
I don't know what CPU you have, but I suspect your CPU bottlenecking it to death, what is your CPU, have you overclocked it ?

I have not, and it's an i5 2500K-.
Well that's odd, the rules says that if you have more FPS than it feels like, the problem is the RAM or CPU
When it's simply low framerate, it's your GPU.
Run Memtest and check if it returns any errors.
What CPU and RAM do you have? If you run on a older Intel CPU or something, it may bottleneck your GPU (bottlenecking is the GPU getting limited performance because the CPU cannot handle it properly)
I have an Intel i5 2500k and 8GB of RAM. DDR3, don't really remember what Mhz it was on, though.
Oh these specs are fine. They won't bottleneck your computer at all. Anyways, try to run Memtest86 from a flash drive or CD and let it run a thorough memory test.
Thorough means all day, not just once.

Woops, another grammar failure, my apologies.
No problem, just making it clear to the OP.
The very latest drivers are not always the best for your computer, I have learned that the hard way. The very same thing happened to be before. I downgraded to some older graphics drivers, and it fixed the problem. Not saying this will work for you, but that's what worked for me.
Yeah I solved it magically by either moving the thing up a slot or restarting. No idea what it was. Thanks for the help guys.
