I have decided to switch over to a 1440p so will the second 780 help?
The reason I wanna get two is if I get my summer job I will have enough for two and if I only buy one il spend the money something stupid. frown.gif

I see a ton of users here with single and dual 780's running 3570K's and above and have yet to see one complaining of CPU bottleneck.

One incident was eyefinity Sleeping Dog maxed out with No AA/AF. Seeing 7970s maxed @ ~80% and my 3770k can go as high as mid to low 80C

I was tweaking for the optimal setting for my rig. I need to record that next time.

what was the CPU usage?

you played @ 4.7Ghz?

I seriously doubt that i5 3570k @4.5 wouldnt bottleneck sli 780 in battlefield 3(MP). But yeah, that was just for a comparison.

I have no doubt they are getting bottlenecked in some games, that doesn't exactly mean its going to have a noticeable effect on gameplay though, just means the cpu is holding back the gpus to an extent. Crysis 3 is definitely going to bottleneck, Farcry 3 in some areas will for sure, BF3 will in multiplayer with large player counts, crysis 1 is going to be bottlenecked for generations at the rate cpu ipc is increasing because of its complete and utter lack of mult threading. We could go on for hours going over the badly cpu optimized or just truly demanding games out there.

don't worry too much about monitor response times these days, buy one with 2MS or 5MS, but really that is just fluff on the box and most new monitors are all these speeds. theyre actually a lot more than 5MS response time, its basically a lie, but the lower they are advertising the faster it is, ie 2MS is better than 5MS, and no you wouldn't notice the difference. its just on older monitors or cheap ones that the response time is so slow they suck.

what they measuring is a time to go from white to black to white or something, and then they only measure like part of it, hence the lie. the actual time is like 15MS or something I think, I believe awhile ago when some benchies were done monitors showed at best a 22 MS response time. basically there is something called input lag on monitors which the manufacturer doesn't advertise, and so one 2MS monitor compared to another may be drastically different in terms of TRUE response time, ie time from video signal sent from gcard > your eyeballs absorbing light.

all that said, get a 2MS monitor from a reputable manufacturer and you will get the best performance for your $$. I like Samsung, but asus seems to be popular around here aswell, and ive had very positive experiences with acer monitors aswell. I have one that is.... 8 years old now? 24" 1920x1200, super nice color, the blacks suck (they all did back then) but its 8 years old!!! and its right here with 0 dead pixels!!

from Wikipedia :

Response time is the amount of time a pixel in an LCD monitor takes to go from one value to another and back again. It is measured in milliseconds (ms). Lower numbers mean faster transitions and therefore fewer visible image artifacts.

Older monitors with long response times would create a smear or blur pattern around moving objects, making them unacceptable for moving video. Long response times can be annoying to a viewer depending on the type of data being displayed and how rapidly the image is changing or moving. Current LCD monitor models (such as those with 120Hz or 240Hz refresh rates) have improved to the point that this is only seen with extreme contrasts. For causes of motion blur, see Display motion blur.

For an LCD display, typical response times are 8 to 16 ms for black-white-black, or 2 to 6ms for grey-to-grey. The response time was traditionally recorded at the full black > white transition, which became the ISO standard for this specification on LCDs. Grey transitions are far more common in practice but in terms of pixel latency, they remained significantly behind the ISO transition. In recent years there have been a wide range of Response Time Compensation (RTC) / overdrive technologies[2] introduced which have allowed panel manufacturers to significantly reduce grey transitions. Response times are now commonly quoted in "GTG" (alternately but less commonly "G2G," both meaning "grey-to-grey"[3]) or "GLRT" (meaning "Gray Level Response Time"[4]). There are various names used for RTC technologies, and these vary from one manufacturer to another. Terms such as ClearMotiv (Viewsonic), AMA (BenQ), MagicSpeed (Samsung) and ODC (LG/Philips) are widely used to identify RTC enabled displays.

With a CRT the response times are much faster, and CRTs do not have the same problems with smearing or ghosting. The same is true for plasma displays. However, older CRTs and plasma displays can have problems with flicker at any refresh rate, and even newer ones can at refresh rates less than about 80 Hz.

LCD screens with a slow response time are often unsuitable to play fast paced computer games. A worst-case response time of >16ms is insufficient for video gaming, due to the human eye being able to perceive differences in response times greater than 5ms. The difference between response times once below 10ms at 60Hz begin to become harder to perceive due to limitations of the human eye.[5][6]

The pixel response time is often confused with the LCD input lag which adds another form of latency to pictures displayed by LCD screens. An LCD screen with high response time and significant input lag will not give satisfactory results when playing fast paced computer games or performing fast high accuracy operations on the screen (e.g. CAD). Manufacturers only state the response time of their displays and do not inform customers of the input lag value.

To address input lag, some modern televisions will offer some sort of "gaming mode" where the TV passes the signal through with minimal processing to minimize any potential image lag.
